AMD's Flagship Fiji XT Card Could Have Two GPUs and 8GB HBM

AMD has yet to fully disclose when and what exactly its upcoming R9/R7 300 series will be like, but there have been some rumors providing various details. Now there's a new rumor, and is it a big one. The flagship product in the R9 300 series, the Fiji XT card, will apparently feature 8GB of HBM and be a dual GPU monster; 4GB of HBM per core. So yes, if this rumor proves true, it seems the flagship card will feature two Fiji XT GPUs on the same PCB, with 4GB of HBM per core. It is been thought the flagship card would be the R9 390X, but maybe that won't be the case here. Maybe we'll have the R9 390X as a high-powered single GPU card using a Fiji non-XT core, or maybe the R9 390X was merely an expected jump and not the true flagship. Perhaps we'll get something else, like an R9 395X or R9 39X2, that is the true flagship, dual GPU beast.

One other element that may lead credence to this new rumor is the recent trend in VR and the Oculus Rift Crescent Bay demo that was supposedly powered by an unknown Radeon flagship. A Liquid VR slide mentioned two GPUs were needed for asynchronous rendering and something called an Affinity Multi GPU. Is that unknown flagship this dual GPU Fiji XT or something AMD is working on for the future? We'll just have to wait and see exactly what AMD has in store for us, hopefully at Computex in June.

Author: Brentt Moore

According to SweClockers, NVIDIA is currently preparing the GeForce GTX 980 Ti, a reduced version of the GM200-powered TITAN X that was released earlier this month. The Ti version of the amazingly efficient and widely popular GeForce GTX 980 is slated to feature 6GB of framebuffer and be around 10 percent faster than the TITAN X. Moreover, the GeForce GTX 980 Ti will be capable of featuring custom PCBs and cooling solutions from various manufacturers, allowing the GM200 card to offer users with even better performance as well as cooler temperatures when compared with the already available GeForce GTX 980.

NVIDIA is expected to release the GeForce GTX 980 Ti during the second half of this year, following the launch of the Radeon R9 390X by AMD.

Thanks to the recently released Catalyst 15.3 beta drivers, DeviceID information is now available for some of the next generation AMD GPUs that are set to hit the market in the somewhat near future. Unfortunately, most of them will be rebrands according to data that is currently available. Sources that compared information within the latest beta drivers with older AMD products found that DeviceIDs for the majority of the Radeon Rx 300 series match already released products. Some of the rebrands include the Radeon R9 370, which is based on Pitcairn; the Radeon R9 360, which is based on Bonaire; and the Radeon R5 310, which is based on Caicos. Mobility graphics cards that fall within the Radeon M300 series will also be based heavily on previously released products.

Author: Nick Harezga

Benchmarks have been leaked that compare the performance of the rumored AMD Radeon 390X and the NVIDIA GeForce GTX Titan X and GTX 980 Ti. The leaks were reported by Chinese site Chiphell and build on previous rumors that AMD would officially announced the card at Computex. The benchmarks were given as a percentage comparison against the Radeon R9 290X. In a 19 game benchmark suite at 4K resolutions the 390X narrowly outperformed the Titan X, while the other NVIDIA cards were beat handily. The Radeon maintained its advantage at lower resolutions as well as in the 3DMark Fire Strike Extreme benchmark. The NVIDIA cards consumed less power than the 390X, but the Radeon still managed to improve on the power consumption of the 290X.

Rumored specifications for the upcoming AMD Radeon R9 300-series graphics cards began to leak early last month, and there are new rumors that hint at when the official announcement of the new cards will be. Sources have indicated that AMD is planning to introduce the new cards during Computex in June. There were some initial plans to release a single new card at CeBIT and a few re-branded cards before Computex, but senior management demanded a "full line up" of cards to be released at the same time. The new cards could be what AMD needs to recover from a year that saw NVIDIA take significant market share in the GPU market with AMD CFO Devinder Kumar stating, "We are confident that as we get into the second half of 2015 with the launch of that [new graphics] product, we will gain back the market share which is low from my standpoint and historically."

Author: bp9801


Earlier today Epic Games revealed it would be holding a keynote address at GDC 2015 that would cover the state of the Unreal Engine and what the future holds. Evidently the future is quite large, as Epic Games is partnering up with Weta Digital, Oculus, and NVIDIA to push virtual reality to a whole new level. Showcasing this new VR possibility is a demo featuring the "Thief in the Shadows" scene from The Hobbit: The Desolation of Smaug. In it we see the great serpent Smaug in his gold pile, talking to the person wearing the Oculus Crescent Bay prototype headset as if the person is actually there with Smaug under the mountain. It is an impressive experience that is made possible with a brand new toy from NVIDIA: the GeForce GTX TITAN X.

The TITAN X is the latest iteration of the company's powerhouse card, with a Maxwell GPU, eight billion transistors, and a 12GB framebuffer. Full details of the TITAN X are still under wraps until NVIDIA's GPU Technology Conference later this month, but CEO Jen-Hsun Huang sounds positively excited about what it can do.

NVIDIA's new card enables the "Thief in the Shadows" demo to run at 90 frames per second on the Crescent Bay headset. Smaug is brought to life before your very eyes thanks to Unreal Engine 4, and sounds like he's right in front of you, too, thanks to the Oculus Audio SDK. Coins clink and fall as Smaug shifts around, his breathing fills your ears, and his massive 500-foot frame dominates your vision when he reveals himself.

Attendees of GDC 2015 can check out the "Thief in the Shadows" demo at the Epic Games, NVIDIA, and Oculus booths. The GTX TITAN X may make an appearance, too, but remember, the full details of that massive card will be revealed in two weeks.

According to a report from Jon Peddie Research, NVIDIA has expanded its lead over AMD in GPU market share over the past year. From the fourth quarter of 2013 to the fourth quarter of 2014 NVIDIA went from 64.9% to 76% while AMD dropped from 35% to 24%. The increase in market share is a bright spot for NVIDIA and its Maxwell GPUs, which have recently been hit with some bad press related to memory issues on the GTX 970 cards. It will be interesting to see if AMD is able to turn it around or if NVIDIA will further increase its market dominance in the coming year.

NVIDIA Hit With Class Action Lawsuit Over GTX 970 Memory Issue

Author: bp9801

It seems things are not quite their best right now, as NVIDIA has been hit with a class action lawsuit concerning the GeForce GTX 970 and its memory. Specifically the lawsuit alleges NVIDIA misled its customers over the performance of the GTX 970 and the extent of the video memory. The video card shows to have 4GB of GDDR5 RAM, yet only 3.5GB is usable with the stated performance. That final 0.5GB lacks an L2 cache, which can cause a slight performance drop when all 4GB is used. The lawsuit says that final 0.5GB runs 80% slower than the rest of the VRAM and negatively affects frame rate and gameplay. NVIDIA did recently announce the exact specifications of the GTX 970, but says the performance drop of the 0.5GB is neglible. The company also said a PR mishap was to blame for the inaccurate specs when the card launched late last year.

Both NVIDIA and Gigabyte are named as defendants in the class-action, which was filed with the U.S. District Court of Northern California. The lawsuit, filed for anyone who purchased a GTX 970, wants a jury trial and payment of whatever damages are necessary under California law. Details on who can claim and when should be forthcoming, if the lawsuit goes through.

Author: Brentt Moore

Due to the latest NVIDIA drivers released just over a week ago, users of the GTX 900M series have been unable to overclock their mobile graphics cards. After many complaints to the company, NVIDIA has decided to reintroduce overclocking capabilities for the GTX 900M series. Although NVIDIA originally stated that overclocking a GeForce card found within a notebook simply carried too much risk, due to thermal limitations of laptops, the outcry of users seems to have brought back the feature. Overclocking capabilities will be included in the next version of NVIDIA drivers, which are slated to be released sometime next month. For users requiring overclocking to make certain games playable before the next driver release, NVIDIA is recommending that users downgrade to version 344.75 of the GeForce drivers.

The latest driver from NVIDIA, GeForce R347, has removed the ability to overclock some GTX 900M series mobile graphics cards. Some users took to the NVIDIA forums to express their concerns, and are unlikely to be happy with the answer they received. Manuel Guzman of NVIDIA addressed the issue stating, "Unfortunately GeForce Notebooks were not designed to support overclocking. Overclocking is by no means a trivial feature, and depends on thoughtful design of thermal, electrical, and other considerations. By overclocking a notebook, a user risks serious damage to the system that could result in non-functional systems, reduced notebook life, or many other effects." Guzman also pointed out that overclocking mobile cards wasn't supposed to be enabled and the company considered the move a bug fix rather than a feature removal.

Author: bp9801


The AMD R9 300 series still isn't technically announced, but that doesn't mean the rumors and unofficial confirmations aren't going to stop showing up. We have something new concerning the new flagship video card, the R9 390X, and it seems to confirm it will be featuring a liquid cooling system built right in. According to the latest leak, the AMD R9 390X features a liquid cooler from Cooler Master to keep the Fiji XT core from being overwhelmed. The liquid cooler is an Asetek model that Cooler Master is licensing, and features a closed loop design and a 120mm fan. Now, the fan and radiator may be right on the 390X, or the rad may be a separate attachment like it is with the R9 295X2. We'll just have to wait and see in that regard. AMD's partners may opt to go with an air cooler on their version of the R9 390X, but those air coolers will have to be fairly robust to compete with the reference card's liquid cooler.

If you're wondering when you can get your hands on an R9 390X, you may not have too long to wait. We may still get the official announcement this month about the R9 300 series, with a launch coming later in March or April. A demonstration of the new cards could also come during March 2 through 6 at GDC 2015, with a soft or hard launch right after. Hopefully we get some confirmation one way or the other, as well as how much we need to drop to get an R9 390X.

AMD's R9 300 Series Nearing Release; Early Details Leaked?

Category: Video Cards
Posted: February 8, 2015 11:10PM
Author: bp9801

It looks like AMD isn't going to sit idly by in the video card world, as apparently it is planning to release the R9 300 series shortly. We may get the new cards this month even, or at the very least around the start of Spring. The flagship card will more than likely be the R9 390X running a Fiji XT core, with an R9 390 on a Fiji Pro core. Considering the R9 290X debuted as the flagship nearly 16 months ago, it is definitely time for AMD to get something new available. These R9 390X cards should be exceptionally fast, as they're expected to make use of SK Hynix's 3D stacked High Bandwidth Memory (HBM) to deliver up to four and a half times the bandwidth of GDDR5. This would mean 640GB/s of bandwidth on a 4096-bit bus and 1.25GT/s transfer rate, with a 1024-bit input/output interface. The R9 390X could have 4GB of HBM, along with 4096 GCN cores and maybe even a water cooler instead of an air cooler.

There is also rumor of a dual-GPU R9 395X2 planned for the end of the year, with a water cooler and $1499 price tag. First things first will be the R9 390X, 390, 380X, 380, 370X, 370, and R7 360 sometime in the next few months. We'll have to see exactly what these cards will be like and if they'll truly have that HBM memory on the 390X, but if so, they may be the new cards to consider. The other cards in the lineup will make use of GDDR5, with the R9 380X having 4GB on a 512-bit interface, the 370X running 3GB on a 384-bit interface, and the R7 360 featuring 2GB on a 256-bit interface.

It was reported yesterday that NVIDIA publically acknowledged a problem that involves how the 4GB of VRAM featured on the GeForce GTX 970 is divided, which causes performance drops when 3.5GB of VRAM is utilized. AMD has decided to take advantage of this news by not only releasing a media document that states “4GB means 4GB,” but also by slashing the price of the Radeon R9 290X. AMD has told its add-in board partners to lower the price of the R9 290X to as low as $299, making the graphics card highly competitive against the NVIDIA GeForce GTX 970. AMD is also emphasizing to consumers that along with the 4GB of onboard VRAM that the R9 290X boasts, the card offers a 512-bit wide memory interface.

With the recent launch of the GeForce GTX 970, users were reporting a drop in performance with their cards. NVIDIA has come out and acknowledged that the problem is related to the way the 4GB of VRAM is divided, causing a performance drop when reaching 3.5GB of VRAM used. NVIDIA employee PeterS took to the NVIDIA forums to tell users that a driver update is in the works that will address the performance issues, stating that the driver will "tune what's allocated where in memory to further improve performance." He went on to add that users who no longer want their cards should "return it and get a refund or exchange. If you have any problems getting that done, let me know and I'll do my best to help." The driver won't be able to give users access to the full 4GB of VRAM, but should increase performance when using large amounts of memory.

NVIDIA Fully Details the Memory Configuration of the GeForce GTX 970

Category: Video Cards
Posted: January 27, 2015 10:49PM
Author: bp9801

Recently some concerns have appeared over the NVIDIA GeForce GTX 970 and its 4GB of memory, namely that it wasn't using all of it. If a game needed to use all 4GB of memory, some people were not seeing the level of performance expected with the GTX 970. According to the specifications released when the GTX 970 launched, it has the same number of ROPs and L2 cache as the GTX 980. Unfortunately, that was never the case, as NVIDIA has now stated the GTX 970 has one fewer ROP and thus one fewer L2 cache to access. So the GTX 970 actually has seven ROPs and 1.75MB of L2 cache to play with, but still the same 1664 CUDA cores and 104 texture units.

So, NVIDIA has now established the ROPs and L2 cache is a little less than initially thought, and attributes that to a snafu between the engineering and PR teams. But what does that mean for the performance and total memory space? Well the GTX 970 may only have seven ROPs, but that 32-bit memory controller segment remains. In a way to counter that, NVIDIA made 3.5GB of memory available to seven memory controllers and their L2 cache, with 0.5GB to that final memory controller without its L2 cache. Many games would only need to access 3.5GB of memory, so there would not be an issue. However, if all 4GB needs to be accessed, then that final 0.5GB segment works at 1/7th the speed of the rest (yet still four times faster than system memory and PCI Express bus can handle). It may sound alarming, but that is only a 4-6% drop in real-world performance, according to NVIDIA's tests. The 224GB/s memory bandwidth, however, is no longer entirely accurate, as it is only met when all 4GB is used and not when it's just the 3.5GB section.

The miscommunication at launch between engineering, PR, and reviewers did result in places labeling the GTX 970 with an incorrect ROP/L2 count is unfortunate, and yes it did take four months for clarification from NVIDIA. However, the GTX 970 still can't technically be called a 3.5GB card, because it does actually have 4GB on it. Just maybe it should be broken down to 3.5GB with a 0.5GB cache. There are still eight memory controllers after all, and the GTX 970 runs on a 256-bit bus. If NVIDIA was still on Kepler and not Maxwell, we'd have a card with a 192-bit bus and only 3GB of memory. As it is, we get a card that didn't need to be hampered in that way, just one that wasn't entirely accurate in what it could do.

All in all, what we have with the GTX 970 is exactly what we should have. When games are accessing 3.5GB of memory or less, the performance is precisely how it should be in any review you can find on OCC or its affiliates. When all 4GB needs to be accessed, there is a small drop in performance, but it should not cause you or anyone else to abandon their GTX 970s for a 980 or equivalent card. NVIDIA made a mistake, has addressed the issue, and is making the consumer aware of what exactly they are getting. Should it have happened sooner? Yes, but we still have an incredibly powerful card that does exactly what it was always meant to. Just not always with accurate specifications. What that means to consumers on the whole remains to be seen, but I imagine any potential backlash (if any) won't be severe.

NVIDIA is introducing a new member of its Maxwell family of video cards today with the GeForce GTX 960. It is aimed at what could be the ideal price/performance ratio, and considering it comes in right around $200, NVIDIA may have a winner on its hands. The GM206 cards feature DirectX 12 support, 128 CUDA cores, 2GB of GDDR5 memory, a 128-bit bus, and a core clock speed of 1126MHz. NVIDIA is letting its board partners release non-reference models today too, so you can find not only the stock NVIDIA version but overclocked ones right away. We have plenty of reviews covering both editions, so hit them all up below to see just what the GeForce GTX 960 is capable of!

Leaked screenshots give us the first look at the upcoming NVIDIA GM200 GPU, the newest based on the Maxwell architecture. The card is built on the PG600 board and uses 24 Hynix H5GQ4H24MFR memory modules, giving the card a 12GB frame buffer clocked at 7GHz. It is expected to use the GM200-400 variant with 3072 CUDA cores, and it is believed that the card will be formally introduced next month.
