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.
