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.
