It appears that Intel has got a new contestant. Applied Micro Circuits, a new upcoming chipmaker, is aiming at the energy saving server market, and, according to Raymond James analyst Hans Mosesmann, it will be a major threat to Intel's business. The company currently has 649 employees and annual sales amount to $195 million, and while this is not much compared to Intel, AMC is optimistic. With a low power, ARM based chip called the X-Gene as it main product, AMC seems to have convinced many analysts that it will be able to compete with Intel. In a recent report from Bernstein Research, analysts have concluded that "[they] see some risks for Intel", and Sergis Mushell from research firm Gartner agrees. A chip expert from the Linley Group, Linley Gwennap, believes that Intel will use whatever they an to ensure that AMC does not gain a foothold.
The X-Gene is a ARM based, 64 bit server processor that has been improved upon to fit AMC's target market. The processor will be running at 3.0 GHz, while using very small amounts of power.The processor is scaleable up to 128 cores with very low latency and quad issue out of order . The chip will also have integrated PCI-Express, storage and network interface controllers.

AMD's APUs have been adopted by many for their good price per performance, especially for builds that forego discrete graphic cards, such as HTPCs. Back in July, two new additions to AMD's APU line up was spotted on MSI's CPU support list. The two APUs, the A8-6500T and the A10-6700T, have a lower TDP of only 45W, which reduces the need for heavy cooling and can therefore lead to more silent computers.
The lower TDP comes at a cost though. The CPU core clock has been set to 2.1 GHz and 2.5 GHz for the A8-6500T and the A10-6700T respectively, with the turbo clocks set to 3.1 GHz and 3.5 GHz. The two iGPUs used, the HD 8550D and the HD 8650D, have both been downclocked to 720 MHz. Other than that, the specifications remain the same. Both have 4 cores, 4 MB L2 cache, and support for AVX and FMA3 instructions. The two APUs will be priced at $112 for the A8-6500T and $142 for the A10-6700T.

Intel has now announced the fourth generation of Core i7 Extreme processors. These new processors are based on the Ivy Bridge-E architecture and uses the LGA 2011 socket found on X79 motherboards. The processors will feature an improved architecture, new extensions to the x86 instrution set, VTx and VT-d technologies, and support for AVX instructions. Furthermore, the processors officially support 3.0 PCI Express, which should remove any bottleneck imposed by any graphics card or other PCI Express card setup currently available on the market, along with a quad-channel memory controller that supports DDR3-1866 memory. The stock speeds on the processors have also been increased by either 100 MHz or 200 MHz depending on the SKU, and this is done while maintaining the same TDP of 130 W found on older Extreme processors.
The prices will range between $310 and $990, and the processors should be launched next week during Intel Development Forum.
|Model||Cores/Threads||Frequency||Turbo frequency||L3 Cache||Memory||TDP|
|Core i7-4820K||4/8||3.7 GHz||3.9 GHz||10 MB||DDR3-1866||130 W|
|Core i7-4930K||6/12||3.4 GHz||3.9 GHz||12 MB||DDR3-1866||130 W|
|Core i7-4960X||6/12||3.6 GHz||4.0 GHz||15 MB||DDR3-1866||130 W|

Since the launch of Haswell, Intel has been retiring older processors to make way for the new generation, and to ensure that consumers buy the latest generation of processors. This time around Intel will been retiring twelve Core i5 processors and three Core i7 processors from the 2nd Generation Core processors. The Core i5 processors going into retirement are: the Core i5 2550K, 2500K, 2500, 2500S, 2500T, 2450K, 2400S, 2380P, 2390T, 2310, and the 2405S. The Core i7 processors going into retirement are: the Core i7 2700K, 2600K, and the 2600S. So if you want an Intel processor that can reach very high clock speeds without needing LN2 cooling, now is the time to buy one before the stores run out.
Two Ivy Bridge processors will also retire to make way for some new Haswell processors. The two Ivy Bridge processors are the Core i5 3450 and the Core i5 3450S. They should make way for the Core i5 4670, 4570S, and 4570, as well as the 4430S.
Despite all these chips getting retired, there is no need to be alarmed. This happens all the time, and it is how Intel makes sure you buy the newest processors. And again, why would you not? The new Haswell processors will have a much better iGPU, improved architecture, support for PCI-Express 3.0, and much more.

AMD announced a new powerhouse some time ago, the 8-core FX-9590, which is the world's first commercially available 5 GHz processor; however, the processor, along with its little brother, the 8-core FX-9370, was not available at that time. They are now though, as they have been seen at TigerDirect, selling for $829 for the FX-9590 and $329 for the FX-9370. The FX-9370 is also available in iBUYPOWER's gaming rigs, though at a slightly higher price of $353.34.
The FX-9590 has a base clock frequency of 4.7 GHz and a max turbo frequency of 5.0 GHz, while FX-9370 has a base clock frequency of 4.4 GHz and a max turbo frequency of 4.7 GHz, and both feature eight Piledriver cores.

If you are starting to feel that your Sandy Bridge-E processor just does not cut it anymore, then fret not for Intel will have you covered soon. New details have been revealed about the upcoming Ivy Bridge-E that is set to be launched in Q3 2013.
|Model||Cores||Threads||Base Clock||Turbo Clock||L3 Cache||Memory||TDP|
|Core i7-4960X||6||12||3.6 GHz||4.0 GHz||15 MB||DDR3-1866||130 W|
|Core i7-4930K||6||12||3.4 GHz||3.9 GHz||12 MB||DDR3-1866||130 W|
|Core i7-4820K||4||8||3.7 Ghz||3.9 GHz||10 MB||DDR3-1866||130 W|
Other than more cores and higher speeds, the Ivy Bridge-E will also feature 30 PCI-Express lanes (third generation); along with various internal changes and better graphics, which can be found in regular Ivy Bridge CPUs as well.
According to a leaked roadmap, we can also expect a Haswell refresh in Q2 2014. This refresh appears to include two new chipsets, Z97 and H97, that support SATA Express, which is said to provide device interface speeds from 8 Gb/s to 16 Gb/s by utilizing PCI-Express lanes. The chipsets will also include Intel device protection, which will protect PCs against malware, and new Intel Smart response and Rapid start technologies with Dynamic Cache Sharing.

I do not know how much you are into supercomputers, but often they use some quite different processors than what is found in consumer PCs. Some of Intel's supercomputer processors are called the Xeon Phi. At the International Supercomputing Conference in Leipzig, Germany, Intel announced some new additions to the Xeon Phi family. Last November, Intel announced 5100 series, which is meant for dense servers. The 5100 series has now been expanded upon with new one called the 5120D. The 5100 series differs from the 7100 and the 3100 by being produced in a different form factor. The 5100 series is shipped as a PCB with the co-processor installed and with 8 GB of on-board GDDR5 memory. The 60 cores inside the co-processor are clocked at 1.05 GHz, and have 30 MB of L2 cache. The PCB uses a 230-pin edge connector, which fits in a x24 PCIe slot. The PCB does not come with a thermal solution, and it is therefore up to the buyer to provide sufficient cooling for the 245 W TDP. The co-processor has a peak performance of 1,011 GFLOPS.
The 7100 series, Intel's high performance co-processors, will be implemented as PCIe cards that house the co-processor and the on-board GDDR 5 memory. The cards have 61 cores that operates at 1.283 GHz. The clock frequency can be brought up to 1.33 GHz via the Turbo Boost feature. The cards have 30.5 MB of L2 cache and 16 GB of GDDR 5 memory. The co-processors' peak performance comes in at over 1.2 TFLOPS. The difference between the two cards is the cooling solution used to manage the 300 W TDP. The 7120P uses passive cooling, while the 7120X uses active cooling.
Intel’s answer to "value" supercomputer co-processors is the 3100 series. The 3100 series are much like the 7100 series; the differences are in the specifications. The 3100 series has only 57 cores as opposed to the 7100 series' 61 cores, and the clock speed has been reduced to 1.1 GHz along with the Turbo Boost feature being disabled. The amount of L2 cache has also been reduced to 28.5 MB, and the on-board memory has been reduced to 6 GB. The co-processors' peak performance is 1,003 GFLOPS. The difference between the two models is the cooling solution. Like the 7100 series, the 3120P uses passive cooling, while the 3120A uses active cooling.
|Model||Cores||Threads||Frequency||Turbo frequency||L2 cache||On-board memory||TDP||Price|
|3120A||57||228||1.1 GHz||N/A||28.5 MB||6 GB||300 Watt||$1695|
|3120P||57||228||1.1 GHz||N/A||28.5 MB||6GB||300 Watt||$1695|
|5120D||60||240||1.05 GHz||N/A||30 MB||8 GB||245 Watt||$2759|
|7120P||61||244||1.23 GHz||1.33 GHz||30.5 MB||16 GB||300 Watt||$4129|
|7120X||61||244||1.23 GHz||1.33 GHz||30.5 MB||16 GB||300 Watt||$4129|

Last year AMD announced it would begin building licensed 64-bit ARM processors as part of the new Cortex-A50 series for its server line. Earlier today the first details of that new series, as it unveiled the Seattle SoCs based on the ARM Cortex-A57. This new line is 64-bit, just like AMD's x86 server chips, and come with either eight or sixteen cores. Each one supports up to 128GB of RAM, features integrated ten gigabit Ethernet (10 GbE), and AMD "Freedom Fabric" technology, which allows for low-power CPU cores to be grouped together into clusters in order to be fed data more efficiently. AMD is planning on both the eight and sixteen-core SoCs to run at 2GHz, with the company saying the ARM chips offer two to four times the performance of the newly announced x86 low-power Opterons.
The Seattle SoCs are expected to begin sampling in the first half of 2014, with shipments set for the latter half. A pair of more tradtional server processors were also unveiled today, with the Berlin CPUs being available in the first half of 2014 and the Warsaw CPUs in the first quarter of next year. The Berlin parts are quad-core chips available in an APU or standalone CPU format, are based on the Steamroller architecture (the second major revision of Bulldozer), and includes support for heterogenous Uniform Memory Access. As for Warsaw, those are twelve or sixteen-core Piledriver CPUs for server motherboard with two or four sockets. AMD claims the Warsaw parts will offer "significantly improved performance-per-watt" than the Opteron 6300 line.

Information on more Haswell chips has been leaked. The Pentiums do not bring much excitement to the table, since they all have fairly low specifications, and there are not any great improvements. The i3 chips do bring some new changes to the table with Haswell's new graphic chips named GT1 (HD4400) and GT2 (HD4600), which should improve the graphical processing power by a fair margin compared to Ivy Bridge and Sandy Bridge. The i5 chips have also seen some improvements with the new GT2 iGPU and slightly higher clock speed than their predecessors. What stands out the most regarding the i7 chips is the large amount of cache for the i7-4960X, which is a massive 15 MB. Other than that it is just a slight improvement compared to last generation, when you look at the figures below.
|Name||Clock Speed||Core count||Cache||Memory||Graphics||TDP|
|G3220||3 GHz||2 / 2||3 MB||DDR3-1600||HD||54W|

During the processor wars from several years ago, speed was the name of the game. Then suddenly it became a battle for cores. Now, however, AMD is combining both of them as it just unveiled the first-ever processors running at 5GHz: the FX-9590. These new FX processors pack eight cores and are based on Piledriver, but the pure speed of the FX-9590 is something special. It's the first commercially available 5GHz processor, but from a company that broke the 1GHz mark in 2000, it's just another record in a long line of them. Initially, the AMD FX 9000 series will be available from system integrators (like MAINGEAR, iBuyPower, and the like) this summer, so you'll have to buy a PC already equipped with the FX-9590. Eventually it'll be available as a separate component later on, just AMD isn't ready to say when.
AMD is also launching the FX-9370, another eight-core model, but it comes in at a slightly more modest 4.7GHz. Both CPUs support Turbo Core 3.0 technology to improve and maximize performance for demanding tasks.

The technology landscape is rapidly changing, with computers being available pretty much anywhere and OSes being composed of more than just one or two big names. AMD has supported Microsoft Windows for the longest time, but now it's opening its doors to other operating systems, namely Google's Android and Chrome OS. AMD is still committed to Windows 8, but sees a huge market with Android and Chrome that it doesn't want to miss. Chips will be designed based on x86 and ARM for the two Google OSes, and will work in both laptops and tablets. Lisa Su, senior vice president and general manager of global business units at AMD, did not say when we can expect AMD-powered Android tablets and Chrome laptops, but that the company is working with Android developers to get apps running on AMD parts.
Windows 8 tablets aren't exactly flying off the shelves, so AMD's move to support Android should open up a larger market to help drive sales. Its previous tablet chips, Z-01 and Z-60, didn't sell well in the Windows devices it was used in, but AMD hopes its new Temash chips will change that. Those chips offer as little as 3.9W of power consumption and up to eight hours of battery life while browsing the Web. Temash is a 64-bit part and designed with Windows 8 in mind , and also are meant to deliver PC-like performance on tablets thanks to its support of DirectX 11. Hopefully those parts can be reworked to take advantage of Android tablets and Chrome laptops, especially since Temash is expected to arrive later this year. It's good to see AMD branching out, and with any luck the move to Google's OSes is a beneficial one.

The NDA has recently been lifted on Intel's upcoming Haswell lineup. The Haswell chips will use a new socket, LGA 1150, instead of the current LGA 1155 package, and will feature a wide range of processors aimed at enthusiasts and the budget market alike. They will follow Intel's familiar naming pattern, being the Intel Core i3/i5/i7 4XXX series, with the higher numbers indicating higher end models. You can read our review on the Intel Core i7 4770K, which features a stock clock speed of 3.5GHz and a turbo clock speed of 3.9GHz. The full specs of a number of the chips can be found in the table below,
|Cores||Threads||TDP (W)||Clock Speed|
|Core i7 4770||Y||4||8||84||3.5GHz - 3.9GHz|
|Core i7 4770S||N||4||4||65||3.5GHz - 3.9GHz|
|Core i7 4770T||N||4||4||45||3.1GHz - 3.7GHz|
|Core i7 4765T||N||4||4||35||2.6GHz - 3.0GHz|
|Core i5 4670||Y||4||4||84||3.6GHz - 3.8GHz|
|Core i5 4670S||N||4||4||65||3.4GHz - 3.8GHz|
|Core i5 4670T||N||4||4||45||2.9GHz - 3.3GHz|
|Core i5 4570||N||4||4||84||3.4GHz - 3.6GHz|
|Core i5 4570S||N||4||4||65||3.2GHz - 3.6GHz|
|Core i5 4570T||N||2||4||35||3.3GHz - 3.6GHz|
|Core i5 4430||N||4||4||84||3.0GHz - 3.2GHz|
|Core i5 4430S||N||4||4||65||2.8GHz - 3.2GHz|
As you can see from the table, most of the mid-high end Intel processors feature four cores and a clock speed of around 3GHz+, which is fairly similar to the current Ivy Bridge chips. All of these chips, however, integrate a 16-lane PCIe 3.0 controller, and support for dual-channel DDR3 memory. There will also be some other low-end Core i3 models that will be introduced later in the year, as well as a BGA package, which is to support Intel's hugely anticipated GT3 graphics package.
In CPU benchmarks, the Core i7 4770K beats the current 3770K by a reasonable amount, some tests with the 4770K run at almost twice the speed of the 3770K which is fairly impressive. On the GPU side, the performance increase from Haswell is somewhat disappointing, despite a performance gain over Ivy Bridge - most games must be running on the 'Low' graphics preset for any chance of a reasonable frame rate at a 1366x768 resolution.
When compared to the Sandy Bridge E series of processors, the Haswell chip begins to show signs of weakness, with the performance gains from the 4770K still falling behind its Sandy Bridge counterpart, now two generations old. Haswell still manages a 7-13% performance increase over Ivy Bridge in its current state, which is unlikely to give any particularly noticeable performance boost in real-life applications. With the release of the i7 4770K this weekend, we expect to see more Haswell processors to be released in the near future.

Intel might finally be making its way into tablets and possibly smartphones soon. It appears Intel has made a deal with Samsung, which means that Samsung's Galaxy Tab 3 will feature a Clover Trail chip with clocks ranging between 800 MHz and 1.6 GHz. The Galaxy Tab 3 will be using Android 4.2.2. and has a 1280x800 pixel display. This comes as a small surprise, since Intel said, when Clover Trail was introduced, that the processor line was intended for low-powered Windows 8 devices.
The deal might bring a little hope to Intel, since the company has been struggling to get into the mobile market, where ARM-based chips are dominating. ARM's architecture is used in most of Apple's, Samsung's, and HTC's mobile products. But with the new Clover Trail line, Intel should be able to gain some market share. The new chips' power requirement has been reduced drastically while maintaining or improving the performance.
Intel also faces ARM on the server market, but Intel has the upper hand in that situation: it has the largest market share. Many companies still chooses to use its products due to the x86 architecture, making them compatible with most applications used in servers today.
It will be interesting to see how the mobile processor market looks in a few years, since both Intel and AMD are trying to enter the it.

Intel has announced its new Silvermont architecture, which is going to improve the Atom line significantly. The new architecture will be based on Intel's 22 nm 3D Tri-Gate SoC, which is faster while using less power than the current generation. Intel claims that Silvermont will deliver up to three times more peak performance or about the same performance as the current generation using only 20% of the power. The new architecture allows for a new out-of-order execution engine, a multi-core and system fabric architecture that is scalable up to eight cores, new IA instructions, and improved power management capabilities, such as low power C states.
Intel foresees that these chips will be used in various applications, such as smartphones, microservers, tablets, entry level laptops, and network infrastructure. Release dates of some of the CPUs based on Silvermont have been announced:
- Baytrail: Quad-core processor for tablets - holiday 2013
- Merrifield: Smartphone processor - by the end of 2013
- Avoton: Microserver chip - second half of 2013
- Rangeley: Routers and other networking gear - second half of 2013
The success of these chips are crucial for how well Intel will do in the growing mobile market. ARM has been dominating the market for quite a while, and other competitors are trying to get their market share as well. Intel needs to get some results soon, if it wants to have a say in the future of mobile computing.

AMD has launched a new division which aims allow companies to design their own processors for specific applications using the basis of AMD's existing APU technology, while incorporating the company's own intellectual property. This has already been applied in the upcoming Playstation 4, which utilises a heavily modified APU based on the Jaguar core, but until now, there has not been a dedicated division for custom chips. It is hoped that the advent of this new division will help generate the profit that AMD so greatly needs.
One example of the application of this new initiative would be use in Smart TVs, where the APU could contain hardware-accelerated decoders for specific video file types. Interestingly, the new division could enable AMD to incorporate ARM cores into its existing APUs, which may eventually open doors for AMD to enter the ARM SoC market. This could then lead to more powerful graphical rendering capabilities on smaller ARM-based devices such as smartphones and tablets.

Intel's Haswell processors are on the way, but it appears some power supplies may have some issues getting things started. A new report shows that Haswell's C6/C7 states require 0.05 amps on the 12V2 rail, which could be a problem as some PSUs can't supply that low level power. If that's the case then it opens up a lot of stability problems or the simple fact of having a PSU shut off entirely. Intel's Reseller Center website includes a handy list of power supplies, and when you sort by a minimum 12V2 load of zero amps, there's a grand total of 23 units that meet the requirement: 19 Corsair, three InWin, and one Seasonic. There could be more that support it that aren't included on Intel's list, but chances are it won't be too many more.
However, despite all of this there is still some good news. Corsair's Robert Pearce believes motherboard manufacturers could disable the C6/C7 states in the BIOS to ensure compatibility with more PSUs. Users can always enable those states later on once their power supply supports them. Corsair is working to make sure all of its PSUs support the C6/C7 states, and hopefully other companies do too.

AMD has today announced two new desktop processors based on its current Piledriver processor architecture. The FX-4350 and FX-6350 follow the current naming convention for AMD processors, the former being a 4-core variant, and the latter featuring 6 cores, but offer improved clock speeds and L3 cache.
The FX-4350 boasts a 4.2GHz clock speed, coupled with 8MB of L3 cache. This makes the FX-4350 400MHz faster than the current FX-4300, and also doubles up on the L3 cache. The FX-6350 on the other hand boasts a 3.9GHz clock speed, and also offers 8MB of L3 cache, similar to the FX-4350. The FX-4350 has a 95W TDP, and ships for $122, whereas the FX-6350 pushes the TDP up to 125W, 30W higher than its FX-6300 counterpart, and is priced at $132.

Prices for Intel’s next generation of processors, Haswell, have been released. The information comes from a Chinese source that was able to get access to information about the MSRP of Haswell. Please keep in mind that the prices below are lower than the actual prices consumers will see; however, they can serve to give an idea of the prices for the new CPUs. For reference, the Core i7-3770k has a MSRP of $332.
It's in the lower part of the table that it gets interesting, because that is where the new generation is slightly cheaper than Ivy Bridge. The i5-4570 is only $189 compared to its predecessor, i5-3570, which costs $213. An interesting detail is that Intel is introducing more chips in the low- to mid-range segment. This could be a sign that Intel intends to win the market for laptops and tablets, since manufacturers of those will be able to choose the best suited chip for the job. The old x6xx chip is back as well, which was left out in Ivy Bridge. So it should now be possible to choose a CPU that suits ones needs and budget exactly.
A reminder as to why you should be excited for Haswell. It is expected to be up to 10-15% faster than Ivy Bridge, the iGPU is said to be twice as fast as HD 4000 iGPU and to top it off it is going to require less power to operate.

According to a report on PC fan site Guru3D, Intel's next generation Haswell chips will be easier to overclock than any previous generation. Haswell chips will reportedly allow overclocking using both the multiplier and modifying the base clock of the chip, which should allow even those using chips with a locked clock multiplier to gain a modest overclock.
As well as this, Haswell chips are said to feature an integrated VRM controller which should allow enthusiasts and overclockers to squeeze the last bit of performance out of their chips. With these features, next generation Intel chips should be able to hit 8GHz using LN2 cooling, which should be enough to rival AMD's FX series which currently dominate the record frequencies.

Intel has announced that its upcoming Haswell series of processors will feature two new DirectX extensions, PixelSync and InstantAccess. The former, PixelSync, enables Order Independent Transparency (OIT), which speeds up the sorting of transparent graphical elements, for example windows, by ensuring they are rendered in the correct order. OIT is a common feature found in DirectX 11 games, however it is not a feature of the API.
Current methods of OIT involve using large amounts of VRAM and bandwidth, neither of which most integrated graphics solutions, including Haswell, excel at. For this reason, Intel has developed its own implementation of the technology which relies less on the bandwidth and VRAM of the processor.
The other extension, InstantAccess, enables the CPU part of the processor to access a location in the GPU memory (even though the CPU and GPU parts of the chip share the same memory, they each have their own allocated sections). This alleviates the requirement to 'copy' the data to the CPU memory, which is very costly in terms of performance.

AMD has today announced the release of its long awaited 'Richland' Accelerated Processing Units (APUs), now called the AMD Elite A-Series APUs. These chips boast up to four traditional CPU cores as well as an integrated GPU based on AMD's upcoming HD8000 series of graphics chips. The chips are designed for use in mid to high-end notebooks, and will begin appearing in stores soon. Low-voltage versions of these APUs are expected to become available later this year.
The improved Richland APU is claimed to outperform mobile Intel Core i7 chips in both straight-out performance and graphical rendering. If this claim transfers into real-world applications, Intel may need to rapidly rethink their mobile CPU line, which is often much more expensive than its AMD counterparts. The AMD A4-5150M and A6-6350M are both dual-core chips, while the A8-5550M and A10-5750M are quad-core chips with improved graphics processors. The chips were first shipped to vendors in December, however no products boasting the chips have yet been released.

AMD has released some additional details on its upcoming Richland desktop APU lineup, which is geared to replace the current Trinity architecture. Trinity was introduced late last year, but lacked the power many users were hoping for. Although Richland remains on the same 32nm Piledriver core as Trinity, it adds support for DDR3-2133MHz RAM, increases CPU clock speeds, and integrates a HD8XXX GPU into the chip. The flagship APU in the Richland series will be the AMD A10-6800K boasting four cores, an unlocked clock multiplier, and an integrated Radeon HD8670 GPU.
The unlocked quad-core Richland APUs all have a 100W TDP, while the other locked chips and dual-core variants will feature a more modest 65W TDP. The Richland series will remain compatible with the current A55/75/85X chipsets, but will also be compatible with new A68/78/88X series chipsets.

According to a DigiTimes report, Intel is planning to host a conference ahead of Computex 2013, held in June where it will announce its upcoming Haswell series of processors. The new processors will be made available from June 2nd, with vendors showcasing their Haswell-based products at Computex. These processors are expected to account for 14-16% of Intel's processor shipments during Q3.
Haswell is the successor to the Ivy Bridge architecture currently applied in Intel Core 3XXX processors, and will make up all Core 4XXX processors, except high-end Ivy Bridge i7 Extreme processors. The launch of Haswell is anticipated by much of the PC market, and will feature a new microarchitecture which allows new chips to be introduced, such as the low power Haswell Y series.

Earlier, during this year's CES, Intel revealed its new Ivy Bridge Y series of processors rated at 7W designed for use in low power laptops and tablets. One of the most surprising details of the new chips were the TDP (Thermal Design Power). This is particularly surprising considering the current-generation 17W Ivy Bridge chips, with the new chips representing a decrease of 10W. It has since been established, however, that the 7W quoted value is not as it may seem on the surface.
Intel has since, however, released a statement that reveals the rated TDP of its new Ivy Bridge chips is, in fact, 13W. This is because Intel's 7W rating is based on the chips' SDP (Scenario Design Point) rating, which is a designed to represent the processor under the stress of mainstream use. SDP is not comparable to the industry standard TDP, and is unlikely to be adopted in the near future.

Intel has recently announced its plans to add a quad-core variant to its Atom series of mobile processors during a press conference at CES. The project, code-named Bay Trail, remains on the existing 22nm process used in most current Intel processors, and will be clocked at 1.2GHz. These Bay Trail processors are to be be ready in time for the 2013 holiday shopping season. Intel also demonstrated a number of tablets with the new Atom chip running the Windows 8 Operating System.
The quad-core chip is targeted at the smartphone and tablet market currently dominated by the likes of Qualcomm, Samsung, and Apple. The reference design phone Intel produced features a 3.5 inch screen and is relatively thin. Intel must make significant improvements over its current series of Atom chips before it can take on much of the smartphone and tablet market.

AMD's eight-core FX-8300 is now available for enthusiasts to play with, after weeks of informed speculation on whether the company would be releasing another cost-effective chip. The big news here is FX-8300's 95W TDP, which is considerably less when compared to the rest of AMD's eight-core Vishera lineup. Running at a default clock speed of 3.30 GHz with 3.60 GHz of TurboCore speed, the AMD FX-8300's four modules packs in eight cores, along with 8MB total L2 cache and 8 MB shared L3 cache. Priced somewhere between the FX-8350 and FX-8320, the FX-8300 retails for an estimated $190. Despite the chip being slower than its siblings (and priced so closely), the drop in TDP is thought of as its main selling point.

According to a recent report, Intel is to release its high-end Haswell i7 mobile processors in April 2013. These high-end processors will all be quad-core, and will have Hyper-Threading technology enabled, allowing two threads to run on each physical core. The chips will have a base clock of between 2.7 and 3.0GHz, and will have turbo frequencies between 3.5 and 3.7GHz. The chips will have 47-57W TDPs and are likely to be used in high-end gaming laptops as well as all-in-one desktops where low power consumption is of paramount importance.
The Haswell series of mobile processors will also come in a variety of variants, including a new H series that will all be quad-core chips with TDPs between 37 and 57W. The report also states the H series chips will use the BGA (ball-grid-array) package in which the processor is soldered directly onto the motherboard itself. The information has not yet been confirmed by Intel, however it would appear that the firm will be introducing BGA processors as an alternative to the mainstream socketed processors. It will be interesting to see the price difference, if any, between the two types of processor.

A supposed Intel powerpoint slide got leaked with some details on the company's upcoming low-powered Ivy Bridge processors, designated as "Y" variants scheduled for a Q1 2013 release. Similar to Intel's next-generation Haswell processors, some of the new Ivy Bridge chips consume lesser power than current models, boasting a TDP of only 10W. The Core i7-3689Y will be the most powerful CPU of the lineup with only two cores at 1.5GHz, but takes only 13W of power. Hyper Threading is enabled with up to four threads, along with 4MB L3 cache and a maximum of 2.6GHz at Turbo Boost. The 1GHz P-2129Y Pentium is among the least power-hungry of the bunch at 10W, but as expected is hindered with no other extras apart from being a dual core with embedded graphics support. The Ivy Bridge "Y" chips are speculated to be targeted primarily for the ultrabook market, and are considered to be the stopgap until the 22nm Haswell architecture makes its way to consumers.
