Introduction:

Are you looking for a new graphics card to install in your system? Maybe you are building a new setup that is not going to be used for heavy gaming, but would still like to have all the bells and whistles that are available, such as DirectX 11 support, AMD Eyefinity, and AMD Accelerated Parallel Processing Technology. Whatever your reason for looking into a new graphics card for your current setup, or maybe a future setup that does not require a lot of graphics processing power and needs to operate silently, you may just want to check out the Sapphire HD6670. Sapphire's HD6670 is going to offer you a graphics card with the latest features, as well as the ability to have a single monitor resolution up to 2560x1600, while not breaking your wallet. I am excited to see how well the HD6670 is going to compare to the other cards that are in its class.

 

 

Closer Look:

Taking a look at the packaging for the Sapphire Radeon HD6670, the first thing that pops out to me is an image of a woman that is in a modern warrior outfit. This image gives me the impression that the Sapphire HD6670 is not only going to produce some very attractive images, but also is ready for battle against some of the other cards in its class. The top left corner of the package contains the Sapphire logo with the 1GB GDDR5 badge printed in the top right corner. Under the 1GB GDDR5 badge is a sticker that lets you know that Sapphire is using a cooler that was designed by Arctic Cooling with the tag "Cool and Silent" printed below it. This lets you know that Sapphire was thinking what this card is going to primarily be used for and decided to place a cooler on it that is not only going to hopefully give us some good temperatures, but also operate silently. The Radeon HD6670 logo is printed toward the bottom of the package to let you know exactly what is packaged inside. Along the bottom edge of the package, you will find the Radeon Graphics, DirectX 11 Support, AMD Eyefinity, AMD HD3D, DisplayPort version 1.2, AMD, and Gaming Evolved badges. When you take a look at the back side of the packaging for the Sapphire HD6670, you'll find a list of the highlighted features with a brief description of each. Sapphire lists 3D Stereoscopic Support, Digital Power Management, AMD Eyefinity Multi-Display, Microsoft DirectX 11, Advanced Memory, AMD Accelerated Parallel Processing Technology, HDMI and Audio support, and AMD CrossFireX.

 

 

 

 

 

 

 

 

Opening up the packaging for the Sapphire HD6670, you will find a cardboard package inside that houses not only the HD6670 card itself, but all the accessories that are included with the card. There is not very much included, but you will find an invitation to the Sapphire Select Club, an installation manual, a drivers CD, and a dongle to convert from a DVI display to a VESA display. Sapphire put the HD6670 in an anti-static bag to help prevent any static electricity related damages during the un-boxing or during the shipping process.

 

 

Now that we have taken a look at how the Sapphire HD6670 is packaged and what comes inside, it's time to take a closer look at the HD6670 itself.

Closer Look:

Looking at the Sapphire HD6670 for the first time, you will notice that Sapphire is using a bright blue PCB like it has been for all its more recent cards. However, unlike a majority of its other cards, there is a smaller cooler covering the the Turks GPU. Sapphire has decided to help keep the overall acoustics of the card as low as possible by installing a cooler from Arctic Cooling that is going to be able to give the best performance while still operating quietly. Sapphire's HD6670 supports the latest Microsoft DirectX 11, as well as Shader Model 5.0 and OpenGL 4.1 for the highest picture quality possible. With the Sapphire HD6670, you are also going to get AMD's Advanced Parallel Processing technology to accelerate the most demanding application by offloading parallel data computing tasks from the CPU to the GPU to help improve the system's performance. When you take a look at the back of the graphics card, you'll see that the standard four-screw mounting system has been used on the HD6670, allowing you to easily remove the cooling solution and put on a different custom cooler if you wish.

 

 

 

 

 

 

 

 

 

 

 

 

 

When it comes down to connectivity to a display device, there are three different options — DVI, HDMI, and DisplayPort 1.2. Right above the display connections on the IO bracket, you will find the "second" bracket has slits in it to help with the cooling of the HD6670, allowing the air to move out of the chassis, in turn helping to create lower ambient air temperatures inside of your chassis. On the back end of the card, there is more room where the HSF has the ability to move the heat that is generated by the GPU out into the chassis to cool the card. On most cards, this is where you would find an external PCI-E power adapter, however the HD6670 does not require any extra power and will be able to get all needed power from the PCI-E 2.0 slot on your motherboard.

 

 

The Sapphire HD6670 has the Turks GPU installed and is clocked in at 800MHz for the stock GPU core and 1000MHz for the stock memory clock, all done on a 40nm manufacturing process to help allow for less power to be used to operate the card, resulting in less heat being generated. There are four Hynix H5GQ2H24MFR T2C 103A memory modules installed on the HD6670 totaling in at 1024 MB of GDDR5 memory, meaning each module has a capacity of 256 MB. Taking a look at Hynix's website, the memory modules installed on the HD6670 are rated to operate at 3.6Gbps and at 1.5V — other than that, there is not that much information available about these modules.

 

 

Sapphire decided to go with a different approach to the cooling solution offered on the HD6670, as it was created by Arctic Cooling. The cooler installed is a very simplistic cooler, but sometimes simplicity works quite well. There is a large base with fins coming off of it, while a fan is placed directly on top of the fin array blowing fresh air on it to dissipate the heat. The base of the cooler is quite smooth and should provide good contact with the GPU, allowing for maximum heat transfer.

 

 

Now that we have taken a nice close look at the Sapphire HD6670, it is time to take a look at the specifications and features.

Testing:

Testing of the Sapphire HD6670 will consist of running it and comparison cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors. Comparisons will be made to cards of equal and greater capabilities to show where they fall on the performance ladder. The games used are some of today's newest and most popular titles to give you an idea of how the cards perform relative to each other.

The system specifications will remain the same throughout the testing. No adjustment will be made to the respective control panels during the testing, other than applying the AA and AF settings manually in the control panel. I will test the cards at stock speeds, then overclocked in order to see the effects of any increases in clock speed. The cards are placed in order from highest to lowest performing in the graphs to show where the cards fall by comparison.

Overclocking:

Overclocking the Sapphire HD6670 was quite easy and routine, as is all graphics card overclocking, especially when you are unable to fine tune your overclock with voltage adjustments. To properly overclock and ensure I was able to get the highest stable clocks, I started off by adjusting the GPU by 20MHz at a time, testing the stability of the card by running a few loops of Crysis Warhead followed by a few loops of 3DMark11. If the tests passed, I would increase by 20MHz more until it was unstable then lowered by 10MHz until it was stable again. The final GPU core clock I was able to get to was 890MHz, which ends up being about an 11% increase. The memory overclocking was done using the exact same procedures. I was able to arrive at about an 18% increase, which was 1180MHz. To make all of these adjustments, I was using the Sapphire TriXX overclocking utility.

 

Maximum Clock Speeds:

In the past, I had used MSI's Kombuster utility to check for stability coupled with the ability to run through the entire test suite. I have found that some game tests would still fail with this utility, so I have moved to testing with several games at maximum settings through several resolutions to verify the clock speeds that are listed below. Why the change? I have found some cards will play fine at a 4xAA setting, but fail when using 8xAA due to the increased graphics load. If it fails, then the clock speeds and tests are rerun until they pass.

Aliens vs. Predator, developed by Rebellion Developments, is a science fiction first-person shooter and is a remake of its 1999 game. The game is based off the two popular sci fi franchises. In this game, you have the option of playing through the single player campaigns as one of three species, the Alien, the Predator, and the Human Colonial Marine. The Game uses Rebellion's Asura game engine that supports Dynamic Lighting, Shader Model 3.0, Soft Particle systems, and Physics. To test this game I will be using the Aliens vs. Predator benchmark tool with the settings listed below. All DirectX 11 features are enabled.

Testing:

Part first-person shooter, part survival horror, Metro 2033 is based on the novel of the same name, written by Russian author Dmitry Glukhovsky. You play as Artyom in a post-apocalyptic Moscow, where you'll spend most of your time traversing the metro system, with occasional trips to the surface. Despite the dark atmosphere and bleak future for mankind, the visuals are anything but bleak. Powered by the 4A Engine, with support for DirectX 11, NVIDIA PhysX and NVIDIA 3D Vision, the tunnels are extremely varied — in your travels, you'll come across human outposts, bandit settlements, and even half-eaten corpses. Ensuring you feel all the tension, there is no map and no health meter. Get lost without enough gas mask filters and adrenaline shots and you may soon wind up as one of those half-eaten corpses — chewed up by some horrifying manner of irradiated beast that hides in the shadows just waiting for some hapless soul to wander by.

Once again, the Sapphire HD6670 was unable to keep up with the competition when it came down to the Metro 2033 testing.

Testing:

Crysis Warhead is a standalone expansion pack situated in time with the story line of the original Crysis. As Sergeant "Psycho" Sykes, you have a secret mission to accomplish on the far side of the island. Along the way there are EMP blasts and aliens to contend with, as you hunt down the KPA chief. This game uses an enhanced version of the CryEngine 2.

In the Crysis Warhead testing, the Sapphire HD6670 was sitting right around half the performance the HD6790 was able to produce.

Testing:

Call of Duty: Modern Warfare 2 is an iteration of the venerable first person shooter series, Call of Duty. Despite its long, successful pedigree, the game is not without substantial criticism and controversy, especially on the PC. Aside from the extremely short campaign and lack of innovation, the PC version's reception was also marred by its lack of support for user-run dedicated servers, which means no user-created maps, no mods, and no customized game modes. You're also limited to 18-player matches instead of the 64-player matches that were possible in Call of Duty 4: Modern Warfare. Despite all this, the game has been well received and the in-house IW 4.0 engine renders the maps in gorgeous detail, making it a perfect candidate for OCC benchmarking. You start off the single player missions playing as Private Allen and jump right into a serious firefight. This is the point where testing will begin. Testing will be done using actual game play with FPS measured by Fraps.

The Call of Duty: Modern Warfare 2 benchmark is showing the same results as the previous benchmarks — the HD6670 was unable to keep up with its counterparts.

Testing:

Just Cause 2 is a third-person shooter that takes place on the fictional island of Panau in Southeast Asia. In this sequel to 2006's Just Cause, you return as Agent Rico Rodriguez to overthrow an evil dictator and confront your former boss. When you don't feel like following the main story line, you're free to roam the island, pulling off crazy stunts and causing massive destruction in your wake, all beautifully rendered by the Avalanche Engine 2.0. In the end, that's what the game basically boils down to — crazy stunts and blowing things up. In fact, blowing things up and wreaking havoc is actually necessary to unlock new missions and items.

In the Just Cause 2 testing, you can see that once again, the Sapphire HD6790 at stock testing had around a 9-16 FPS advantage on the HD6670.

Testing:

Unigine Heaven Benchmark 2.1 is a DirectX 11 GPU benchmark based on the Unigine engine. What sets the Heaven Benchmark apart is the addition of hardware tessellation, available in three modes — Moderate, Normal and Extreme. Although tessellation requires a video card with DirectX 11 support and Windows Vista/7, the Heaven Benchmark also supports DirectX 9, DirectX 10 and OpenGL. Visually, it features beautiful floating islands that contain a tiny village and extremely detailed architecture.

The Unigine 2.1 benchmark shows that the Sapphire HD6670 is able to run DirectX 11 benchmarks, however it is unable to produce high FPS. The Sapphire HD5830 Xtreme was the closest card by 9 FPS in the 2560x1600 overclocked test.

Testing:

Battlefield: Bad Company 2 is a first-person shooter developed by EA Digital Illusions CE (DICE) and published by Electronic Arts for Windows, PS3 and XBox. This game is part of the Battlefield franchise and uses the Frostbite 1.5 Engine, allowing for destructible environments. You can play the single player campaign or multiplayer with five different game modes. Released in March 2010, it has sold in excess of six million copies so far.

The Sapphire HD6670 got pretty close to the performance that the HD5830 Xtreme was able to produce in the Battlefield: Bad Company 2 testing, coming around 4 FPS away from it at the 2560x1600 stock test.

Testing:

3DMark 11 is the next installment for Futuremark in the 3DMark series with Vantage as its predecessor. The name implies that this benchmark is for Microsoft DirectX 11 and with an unintended coincidence, the name matches the upcoming date in number (which was the naming scheme to some prior versions of 3DMark nonetheless). 3DMark 11 is designed solely for DirectX 11 so Windows Vista or 7 are required along with a DirectX 11 graphics card in order to run this test. The Basic Edition has unlimited free tests on performance mode whereas Vantage only allowed for a single test run. The advanced edition costs $19.95 and unlocks nearly all of the features of the benchmark and the professional edition runs $995.00 and is mainly suited for corporate use. The new benchmark contains six tests, four of which are aimed only at graphical testing, one to test for physics handling and one to combine graphics and physics testing together. The open source Bullet Physics library is used for physics simulations and although not as mainstream as Havok or PhysX, it still seems to be a popular choice.

With the new benchmark comes two new demos that can be watched, both based on the tests but unlike the tests, these contain basic audio. The first demo is titled "Deep Sea" and have a few vessels exploring what looks to be a sunken U-Boat. The second demo is titled "High Temple" and is similar to South American tribal ruins with statues and the occasional vehicle around. The demos are simple in that they have no story, they are really just a demonstration of what the testing will be like. The vehicles have the logos of the sponsors MSI and Antec on their sides with the sponsorships helping to make the basic edition free. The four graphics tests are slight variants of the demos. I will use the three benchmark test preset levels to test the performance of each card. The presets are used as they are comparable to what can be run with the free version so that results can be compared across more than just a custom set of test parameters.

In the 3DMark 11 benchmark, you are able to see that the HD6670 was getting about half the score the closest card was able to produce, which was the HD6790.

Testing:

Featuring all-new game tests, this benchmark is for use with Vista-based systems. "There are two all-new CPU tests that have been designed around a new 'Physics and Artificial Intelligence-related computation.' CPU test two offers support for physics related hardware." There are four preset levels that correspond to specific resolutions. "Entry" is 1024 x 768 progressing to "Extreme" at 1920 x 1200. Of course, each preset can be modified to arrange any number of user designed testing. For our testing, I will use the four presets at all default settings.

The Sapphire HD6670 was still unable to beat any of the other cards it was compared against.

Testing:

Temperature testing will be accomplished by loading the video card to 100% using MSI Kombuster, which is paired with MSI's Afterburner overclocking utility for temperature monitoring. I will be using the stability test set to a resolution of 1920 x 1200 using 8xAA. I will use a 15 minute time frame to run the test, ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card's BIOS for the stock load test, with the fan moved to 100% to see the best possible cooling scenario for the overclocked load test. The idle test will be a 20 minute cool down with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running the overclocked idle and load testing. For load testing the GTX 500 series, I will use Crysis Warhead running at 2560 x 1600 using the Gamer setting with 8xAA looping the Avalanche benchmark scenario, as I have found this to put a load close to that of Kombuster on a video card. This is needed as a way around the current limiting ability of the GTX 500 series when it detects programs that put an unrealistic load on the GPU, which Kombuster does.

Lower = Better

 

The temperatures that the Sapphire HD6670 was able to give was about middle of the pack at the idle testing. However, it was one of the coolest cards during load testing.

Testing:

Power Consumption of the system will be measured in both idle states and loaded states and will take into account the peak voltage of the system with each video card installed. I will use MSI Kombuster to load the GPU for a 15 minute test and use the peak load of the system as my result for the maximum load. The idle results will be measured after 15 minutes of inactivity on the system. For load testing the GTX 500 series, I will once again use Crysis Warhead run at 2560 x 1600 using the Gamer setting with 8xAA looping the Avalanche benchmark scenario.

Lower = Better

 

During the idle testing, the Sapphire HD6670 was once again right in the middle of the other cards, while during the overclocked testing, it fell down toward the end of the pack, meaning it was using the least amount of power out of the other cards — the only card that was lower in power was the HD6790.

Conclusion:

Going back to the first question that I asked at the beginning of the review — are you looking for a new graphics card for your system? Well if you answered yes to this question and you are not looking to break any world records or play video games with maxed out settings, you may just have the right card in mind. If you are looking to build an HTPC or a system that is going to need a few monitors connected to it, the Sapphire HD6670 may be just what you are looking for. Sapphire's HD6670 graphics card is going to give you DirectX 11 support, as well as the ability to run AMD's Eyefinity for right under $100, but you are not going to be able to run the latest games at maximum resolution and have all your DX 11 graphics options enabled and turned up to the maximum settings. Nevertheless, you should still be able to play some of your favorite older games at pretty decent frame rates. In addition, you are going to get a graphics card that will provide you the option to connect a display device using either an HDMI cable, DVI, or DisplayPort 1.2 port, which is just about perfect if you were looking to build a new HTPC and not spend a whole lot on a graphics card.

The overclocking of Sapphire's HD6670 was not the greatest that I have seen, but this graphics card was not designed to be the highest clocker, nor was it designed with high 3DMark scores in mind. Where this card does shine is in the temperature and power consumption testing. The Sapphire HD6670 was one of the coolest running graphics cards during both the stock and overclocked load testing, and was also pulling the least amount of power during both of those tests. I would suggest this card to anyone who is looking to build a new computer on a budget and is not a heavy gamer. I would also suggest this card to anyone who is building an HTPC that wants a quiet running card that is also going to give them multiple connectivity options while not jacking up their power bill.
