Introduction:

Are you looking for a new video card for your current setup? Maybe you have been waiting for a decently priced card to come out that has some good features and supports DirectX 11. Heck, maybe you are building a new computer that is going to be used for light gaming but you still want to be able to have some of the higher graphics settings that a majority of the new games support such as DX 11's Tessellation. Well, whatever your reason for wanting to pick up a new graphics card for either a future build or upgrading your current solution, Sapphire has released the HD6750 and HD6770 as well as added a new cooler to the HD6670 as the Ultimate edition. I am curious to see exactly how these three cards are going to be able to perform when they are put up against some of the other cards on the market, so let's get into the testing and see.

 

 

Closer Look:

When you first look at the packaging for the Sapphire HD6750 and HD6770, you are going to see that they have a bunch of similarities, the woman depicted on the front of each package is not the same. However, they are both ready for battle! The Sapphire HD6750's packaging is going to have a greenish background with a redhead woman holding a pistol that is in a sexy warrior outfit while the woman pictured on the Sapphire HD6770 has a red background and has a sword on her back. On both of the packages you will find the Sapphire logo in the upper left hand corner of the package with the 1GB GDDR5 badge in the upper right hand corner. Along the bottom of each package, you will find the name of the card, be it the HD6750 or HD6770. Listed across the bottom of the package you will find a list of badges that let you know the more important highlighted features of each card, which happen to be the same. You will find the Radeon Graphics, AMD Black Vision, AMD Eyefinity, Onboard HDMI and DisplayPort, CrossFireX Ready, and AMD Accelerated Parallel Processing Technology badges listed here. You are also going to see along the bottom under the list of badges Microsoft DirectX 11, PCI Express 2.1 and CrossFireX Ready printed to give you a little more information about the card. When you flip the package over and look at the back, you are going to find a more detailed list of the features that each card has with a nice quick description of each if you are not familiar with them. You are also going to find an introduction paragraph off to the left side of the package that lets you know what to expect from each card.

 

 

 

 

 

 

 

The packaging for the Sapphire HD6670 Ultimate does look quite different than the HD6750 and HD6770 we just looked at. The front of the package does not include the typical image of a woman on the front, however you will find her on the back side of the package. The top left hand corner of the package displays the Sapphire logo with the "Get Radeon in your system" tag in the top right hand corner of the package. In the center of the package you will find the Ultimate logo with Radeon HD6670 printed below. There is a 1GB GDDR5 badge in the upper right hand corner with the Dirt 3 Game Code sticker next to that as well. Towards the bottom of the package, you will find the HDMI extension cable badge. You will also find a picture of a fan with the tag saying "Enjoy the silence No Fan!" next to it, letting you know that there is no active cooling installed on the HD6670 Ultimate. When you take a look at the back of the package, you will find a list of the highlighted features as well as a nice little description of each.

 

 

Once you get the packages opened up to reveal what is inside, you are going to find that they are both packaged almost identically and have the just about the exact same contents with the exception of the cards themselves being different. The Sapphire HD6750 is pictured on top and the HD6770 on the bottom. You are going to find all of the documentation sitting on top of the graphics card with the VESA to DVI dongle and the 4pin molex to 6pin PCI-E dongle resting under the card. In each package, you will find a drivers CD, a Sapphire Select Club invite, and a user manual. In the Sapphire HD6750 package, you are going to find one extra piece of paper, this is a warning that lets you know that there is a protective film on the cooler that you need to remove before you begin to use the card as it will hinder the cooling performance of the card.

 

 

 

Once you get the packaging opened for the Sapphire HD6670 ultimate, you are going to find that the inner brown packaging is separated into two sections, one has the card itself while the other has a section that holds the HDMI cable and the VESA to DVI dongle. Other than the HDMI cable and the dongle, you are going to find the drivers CD, Sapphire Select Club invite, as well as a user manual. The Sapphire HD6670 Ultimate also comes with a free Dirt 3 code.

 

Well now we know exactly how the Sapphire HD6750, HD6770, and HD6670 Ultimate are packaged and what comes with them. Let's take a closer look at the cards themselves.

Closer Look:

After you get the Sapphire HD6670 Ultimate out of the packaging, you are going to see that the card looks very different from other typical cards you are going to find. This is because of the cooling solution that is installed on Sapphire's Ultimate edition of the HD6670. Sapphire wanted the HD6670 Ultimate to be silent. The best way to do this would be to install a passive cooling soluiton on the card. There are little heat sinks installed on the voltage regulators on the board to help keep their temperatures low to ensure that they are not going to fail due to excessive amounts of heat. The HD6670 is going to come packed with features such as DirectX 11 support, Shader Model 5.0, OpenCL 1.1 and DirectCompute 11. All of these features are going to help you accelerate any of your applications that can use them to reduce your rendering times.

 

 

 

 

 

 

 

 

 

 

 

 

Looking at the type of connections you are going to get with the Sapphire HD6670 Ultimate, you are going to see that just about every type of display adapter is supported right out of the box. You have a DisplayPort, DVI, and HDMI output. With the included HDMI cable you could easily connect your PC to your TV and with the DVI to VESA dongle you can connect to an older monitor. The Sapphire HD6670 Ultimate does not support CrossFireX so there is no CrossFire connection at the top of the card. The HD6670 Ultimate also does not require any extra power from the PSU so there is no PCI-E power adapter at the back of the card. The card does however have a larger heat sink cooler installed on it as a passive cooling solution to ensure it is silent during operation. To keep the temperatures low, the heat sink wraps on to the other side of the card and there are little heat sinks installed on the voltage regulators.

 

 

Once you get the cooler taken off of the Sapphire HD6670 Ultimate, you are going to be able to see the entire layout of the card. The Turks GPU is going to come clocked in at 800 MHz and was manufactured on a 40nm process. The Hynix H5GQ2H24MRA T2C 110A memory modules installed on the card are rated to operate at 1.5V for both the VDD and VDDQ with a 32ms refresh rate. The modules are lead and halogen free, giving them the ROHS3 compliant certification. These chips are the first generation die.

 

 

The cooler that is installed on the Sapphire HD6670 Ultimate does not feature any active cooling solution, meaning it is completely silent. To achieve this, the heat sink needed to be much larger than what you would find on your typical graphics card. The base of the cooler has two heat pipes that have direct contact with the GPU Core and then travel up to the large fin array that is positioned above the graphics card. The bottom section of the heat sink is a large heat sink to help draw the heat off of the GPU.

 

Closer Look:

Once you get the Sapphire HD6750 out of the package and the antistatic bubble wrap, you are going to see that it looks like your typical mid-range card with a simple air cooler installed for the cooling solution. You are going to see a nice bright blue PCB with a glossy black cooler installed on the GPU that is also going to give some cooling to the memory chips and voltage regulators. The cooler that Sapphire chose to use on the HD6750 has no logos or printing on it with the exception of the sticker that is in the middle of the fan that has the Sapphire logo printed on it that happens to be a hologram type sticker. Looking at the back side of the card, you are going to see that the typical four screws hold the cooler down and in place, meaning you could easily upgrade the cooling if you needed to do so for any reason. You are going to find DirectX 11 support on the Sapphire HD6750 as well as Shader Model 5.0, OpenCL 1.1, and DirectCompute 11 all to help accelerate your graphics intensive applications for better rendering time.

 

 

 

 

 

 

 

 

 

 

 

 

On the rear IO shield you are going to see that there are a total of three connections that you can possibly make with a display device. You have DVI, HDMI and DisplayPort. With the included DVI to VESA dongle, you are going to be able to connect to just about any monitor that you possibly need to. There is one single 6 PCI-E power adapter that is located at the back of the card and is right under the back end of the cooler installed on the card. There are two CrossFireX ports located at the top of the card that will allow you to expand your graphics processing power by adding another HD6750 to your system. The cooling solution will bring cool air into the cooler by sucking it down though the fan that will then cool the fins on the cooler and be expelled out the front of the card through the I/O shield and out the back of the card.

 

 

 

Sapphire's HD6750 graphics card with the cooler taken off does allow you to see exactly what the card looks like. You are going to see the GPU in the center of the card with four memory modules positioned around it. The GPU core comes clocked in at 700 MHz at stock and was built using a 40nm process. The Hynix H5GQ2H24MRA T2C 110A memory modules installed on the card are rated to operate at 1.5V for both the VDD and VDDQ with a 32ms refresh rate. The modules are lead and halogen free, giving them the ROHS3 compliant certification. These chips are the first generation die.

 

 

Looking at the cooler with it taken off, you are going to see that it looks very similar to a stock Intel CPU cooler wrapped around a plastic shell to direct the airflow. There is a circular heat sink that has a fan installed on the top of it to bring fresh cool air down to the heat sink and dissipate the heat that is being pulled off of the GPU.

 

 

Closer Look:

After pulling the Sapphire HD6770 out of the packge, you are going to see that there is an upgraded cooling solution compared to the HD6750. The cooler that Sapphire put on the card is much larger and covers just about the entire card and hangs off the back end. You are going to see that the Sapphire logo and Radeon HD6770 are printed on the left hand side of the fan and on the right hand side you will find the AMD Radeon badge printed. In the center of the fan you will once again find a Sapphire logo, however this one is not holographic. The PCB of the card is still a bright blue color and looking at the back, the cooler is installed the same way with four screws to keep it in pace. You are still going to find DirectX 11 support on the Sapphire HD6770 as well as Shader Model 5.0, OpenCL 1.1, and DirectCompute 11 all to help accelerate your graphics intensive applications for better rendering time.

 

 

 

 

 

 

 

 

 

 

 

 

The Sapphire HD6770 comes with support for three different display adapter connections. You have support for HDMI, DisplayPort, as well as DVI. You are also going to be able to get a VESA monitor to connect to the card with the DVI to VESA dongle that was included in the package. The cooler works the same way as the one on the HD6750, fresh air is going to be sucked in through the fan and spread out though the innards of the cooler and expelled through the front and back of the card out the openings. You do get CrossFireX support on the HD6770 and there are two connections at the top of the card that will allow you to expand your graphics power by adding another HD6770 to your system. There is a single PCI-E 6pin power adapter that is located at the back of the card under the back end of the cooler. However, this adapter is somewhat hard to get to because of how far the cooler hangs over the back end of the card.

 

 

 

The Sapphire HD6770 graphics card has the GPU positioned in the center of the PCB with the four memory modules positioned around it; two at the top and two to the right hand side of it. The Hynix H5GQ2H24MRA T2C 110A memory modules installed on the card are rated to operate at 1.5V for both the VDD and VDDQ with a 32ms refresh rate. The modules are made lead and halogen free, giving them the ROHS3 compliant certification. These chips are the first generation die. The GPU comes clocked in at 850 MHz at stock speeds and was put together using a 40nm, manufacturing process.

 

 

The cooler that is installed on the Sapphire HD6770 is what you are going to typically find on your reference cards and your more mid-range performing cards. The cooler takes advantage of not only a large heat sink but putting heat pipe technology to its advantage. The base of the cooler is a copper base that sits directly on top of the GPU core. There are two copper heat pipes that come off of the base and into two different directions into the fin array to help dissipate the heat and keep it away from the core, allowing for the heatsink to pull more heat off of the GPU. The fan is installed in the center of the heat sink and has the outer plastic shell to help direct the airflow to make sure the cooler air being pulled in is used properly.

Testing:

Testing of the Sapphire HD6670 Ultimate, HD6750, and HD6770 will consist of running them 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, with the exception of the 3DMark Vantage testing, where PhysX will be disabled in the NVIDIA 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. The drivers used are the 11.5 Catalyst drivers for the AMD based cards and the 275.27 for NVIDIA based cards

 

Comparison Video Cards:

 

Overclocking:

When it comes down to the overclocking of the cards, it was as always quite straight forward. The methodology behind the overclocking of all three of the graphics cards is to slightly increase the GPU core clock by 20 MHz and then run a few loops of Unigine 2.5 and Crysis Warhead until it becomes unstable. Once the card was unstable, the clock needed to be brought down by 10MHz until it became stable again during the testing. After the GPU core clock has been found, it was then time to overclock the Memory clock using the same method as overclocking the GPU Core.

The Sapphire HD6670 Ultimate was able to give me a maximum clock of 870 MHz on the GPU core and 1140 MHz on the memory core, the Sapphire HD6750 was able to hit a maximum of 840 MHz on the GPU clock and the memory clock was a maximum of 1340 MHz. Finally the HD6770 had a maximum GPU Core clock of 960 MHz and 1320 MHz on the memory clock.

 

 

Maximum Clock Speeds:

Testing for the maximum clock speed consists of looping Crysis Warhead and Unigine 2.5 for 30 minutes each to see where the clock speeds will fail when pushed. If the clock speed adjustment fails, then the clock speeds and tests are rerun until they pass the full one hour of testing.

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.

The Sapphire HD6770 was able to perform at both stock and overclocked speeds the same as the ASUS GTX 550 was able to. The HD6750 was slightly behind that with the HD6670 Ultimate trailing in at the end of the cards being compared.

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.

In the Metro 2033 testing, the HD6770 was sitting right below the HD6790, as it should be. The HD6750 and the HD6670 Ultimate were right behind the HD6770 with the HD6670 trailing behind the HD6750 by about 4 FPS during the 1920 x 1200 stock testing.

Testing:

Civilization V is a turn based strategy game. The premise is to play as one of 18 civilizations and lead the civilization from the "dawn of man" up to the space age. This latest iteration of the Civilization series uses a new game engine and massive changes to the way the AI is used throughout the game. Civilization V is developed by Firaxis Games and is published by 2K games and was released for Windows in September of 2010. Testing will be done using actual game play with FPS measured by Fraps through a series of five turns,150 turns into the game.

Published by Capcom, Lost Planet 2 is the sequel to Lost Planet: Extreme Condition and uses the MT Framework 2.0 engine. The storyline takes place on the fictional planet E.D.N. III some 10 years after the events of the first game. This time, the snow cover is gone and has been replaced by a tropical landscape. With this new rendition of the game comes the ability to run it using either DirectX 9 or 11. Along with this ability comes the chance to use that new DX 11 hardware to effect. DX11 features in this game include tessellation, displacement mapping on water, bosses and player characters, soft body compute shaders on “Boss” characters, and wave simulation by way of DirectCompute. This gives you smoke that is lifelike and reacts to inputs, water that looks and reacts how you would expect it to in a "real life" situation, and "Boss" characters rendered with more depth and detail. If the latest graphics quality settings are not enough, NVIDIA has included support behind this game for both 3D Vision and 3D Vision Surround, which gives you 3D effects over multiple screens. There is no better way to see how a game will perform than to test it out. Capcom has made this easy with a downloadable benchmark that we will be using to test out a cross section of today's currently available performance video cards.

Once again, here in the Lost Planet 2 benchmark, you are able to see that the HD6770 is sitting right around the middle of the pack (right under the HD6790) with the other cards following right behind it. The two HD6670s were able to give the same scores.

Testing:

Unigine Heaven Benchmark 2.5 is a DirectX 11 GPU benchmark based on the Unigine engine. This was the first DX 11 benchmark out to allow testing of DX 11 features. 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, DirectX 11 and OpenGL 4.0. Visually, it features beautiful floating islands that contain a tiny village and extremely detailed architecture.

Sapphire's HD6770 was able to sit right around the middle once again in the Unigine 2.5 benchmark, the HD6750 was trailing close to it with the two HD6670s at the bottom of the chart.

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.

The Sapphire HD6770 and the ASUS GTX 550 Ti were running neck and neck during all of the resolutions in the Just Cause 2 benchmark. The HD6750 was running fairly close to the HD6770 in the overclocked testing, only being a few frames away from it. The HD6670 Ultimate trailed the end once again.

Testing:

Mafia II is a third-person shooter that puts you into the shoes of a poor, Sicilian immigrant, Vito Scarletta. Vito has just returned home from serving overseas in the liberation of fascist Italy — to avoid serving his jail sentence — to find his family in debt. The debt must be repaid by the end of the week, and his childhood friend, Joe Barbaro, conveniently happens to have questionable connections that he assures will help Vito clear the debt by that time. As such, Vito is sucked into a world of quick cash. Released in North America for PC in August of 2010, the game was developed by 2K Czech published by 2K and uses the Illusion 1.3 game engine.

Once again you are going to find the HD6770 in the exact middle of the pack during the BFBC2 testing, the HD6670 Ultimate is at the end of the pack like it has been thoughout the testing.

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 testing, the Sapphire HD6770 and the ASUS GTX 550 Ti were once again playing a cat and mouse game being within just a few marks away from each other. The HD6750 was sitting below the HD6770 with the HD6670s at the end of the group.

Testing:

Temperature testing will be accomplished by loading the video card to 100% using Crysis Warhead with MSI's Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920 x 1200 using 8xAA. I will use a 10-run sequence 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.

During the Stock Load testing, the HD6770 was the coolest running card with the HD6670 Ultimate (passive cooling) behing the hottest card. This was similar during the Overclocked Load testing, the ASUS GTX 550 Ti however was the coolest, beating the HD6770 by 3°C. The HD6670 Ultimate was the hottest running card during the Overclocked 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.

The Load testing at both stock and overclocked speeds shows the HD6770 in the middle of the pack with the HD6750 using less power, followed by the HD6670s using the least amount of power.

Conclusion:

What is there to say about the new Sapphire line up? Well if you are looking for a new mid-range card, you are going to be able to find one in this lineup, no matter what your needs are. If you are looking for a card that is going to give you some good performance in the $120 range, the Sapphire HD6770 is going to be right there for you. All three of the cards that I took a look at in this review were able to overclock quite nicely. The HD6670 Ultimate got 9% on the GPU and 14% increase on the Memory. The HD6750 was able to get 20% and 17% on the GPU and Memory while the HD6770 was able to get 13% and 10% on the GPU and Memory as well. All three of the cards were within the top four for the Load testing (at both stock and overclocked) in the Power Consumption testing. This is going to help you reduce the total power consumption of your setup if you are looking to upgrade your current graphics card to a newer and more efficient GPU core.

The overall performance of the HD6770 throughout the testing was in the dead middle when compared to the other cards and was giving performance in just about all of the tests similar to the GTX 550 Ti, which according to Newegg at the time of this review is priced about $20 higher than the HD6770. During the 3DMark 11 benchmark; in the Extreme section of the testing, the HD6770 was able to actually outperform the GTX 550 Ti by about 30 3DMarks at stock speeds. When it comes down to the HD6670 Ultimate's performance, it was able to hang in with the HD6670, as it should due to the fact that they are the same card. However, these two cards were at the bottom end of the charts in every single graphics performance test performed. Looking at the temperatures that these cards were able to yield, the HD6770 was one of the two coolest running cards at both stock and overclocked load testing, with the HD6670 Ultimate was the hottest running graphics cards tested. I was expecting the HD6670 Ultimate to be the hottest card due to the fact that it does not have any active cooling solution installed on the card to ensure that the card would run silent, which would make it a great solution for someone who is looking to build an HTPC that does not need a low profile card.

No matter what you are looking for in a graphics card, Sapphire has a solution for you with the release of the HD6770, HD6750 and HD6670 Ultimate. The HD6770 or HD6750 would make a great solution for someone who is building a mid-range gaming PC that does not need to run the latest games at the highest possible settings that the games offer. While the HD6670 Ultimate would make a great choice for a PC that is aimed at being silent in operation and needs the extra graphics power to give HD video playback. For the prices of the cards, I would suggest anyone looking to upgrade their current graphics solution to check out one of the new Sapphire cards.
