Taking the first look at the Sapphire HD6790, you are going to see a large cooler that does cover the entire card, it is black with a large sticker at the back end of the card with the Sapphire Radeon HD6790 logos. There is a large fan located in the center of the cooler that is going to suck in fresh air from inside your chassis and blow it directly down onto the heatsink. The PCB of the card is the signature blueish teal color that Sapphire tends to use on their cards that they bring out. You are going to be getting 800 steam processors on the Sapphire HD6790 graphics card with 40 texture units for your Advance Parallel Processing. The stock core clock speed is 840MHz and the 1GB of GDDR5 memory on a 256-bit bus comes clocked in at 1050MHz. You are going to be getting all of the connectivity functions on the HD6790 that you would the higher-end cards such as AMD HD3D and AMD Eyefinity.
The rear IO panel of the Sapphire HD6790 is where you are going to find all of the ways that you can connect a display device to the card. The HD6790 has two DVI outputs, an HDMI and a DisplayPort version 1.2 adapter on it. Above the HDMI and DisplayPort outputs there is a vent that is going to allow some of the hot air that the card is producing to be blown out of the case to help keep the ambient air inside your chassis a bit cooler. The rest of the hot air is going to be exhausted out of the rear of the card where there is nothing hindering the air flow.
At the top of the card you will find a single CrossfireX connector, this is where you are going to be able to install a Crossfire bridge to allow data to be off loaded to a secondary card to help increase the graphics power that your computer is going to be able to output. The rear of the card is where you will find the additional PCI-E power adapters. The Sapphire HD6790 requires two 6 pin PCI-E power adapters, whereas some of the other HD6790s only require one.
After taking a look at the Sapphire HD6790 itself, the next step would be to check out the specifications and features then jump right on into the testing of the card.
