Sapphire Radeon HD 6990 4GB Graphics Card

An Even Closer Look
The 6990 from Sapphire features a simple black plastic outer casing that we’ve come to expect. We all at eTeknix can’t wait to see some custom cooler designs on this card, but time will only tell. The middle of the casing includes a fan that looks very familiar, and reminds us of what’s been used on other 6900 cards which can only mean it’s going to be quite noisy. The back also features a similar style design that keeps the components close together.

The 6990 casing comes off fairly easily and displays the thermal pads and copper heatsinks that will keep the two GPU cores and memory as cool as possible.

Once the cooler has been completely removed, it will showcase the two GPU cores in all their glory and will reveal the other main components of the card.

The two GPUs feature the AMD logo on them and are surrounded by mass amounts of memory chips. Something you expect when you have a graphics card with 4GB of GDDR5 memory.

The memory used on this particular graphics card are Hynix GDDR5 memory chips. The code on the chips are H5GQ2H24MFR-T2C. These Hynix chips run at 1250MHz (5000MHz).

Between the two GPU’s is an ATI branded chip which acts by connecting the two GPUs together using the PCI-Express interface.
