AMD’s behemoth takes the crown, yet again.
Since the end of 2010 AMD has successfully launched their 2nd generation DX11 cards from the highest-end HD 6970 to the entry-level HD 6850. AMD’s top-end HD 6970 may have been enough to beat Nvidia’s 2nd tiered GTX 570, but it was still no match for the GTX 580. Ironically the claim to the world’s fastest single card solution was still held by AMD’s very own HD 5970. Last week AMD launched their newest flagship graphics card, the HD 6990.
A follow up to their wildly successful and incredibly expensive HD 5970, the HD 6990 carries two HD 6970 cores and 4GB of ram on a single PCB. And much like the HD 5970, the HD 6990 measures a cool 12″, so make sure your PC case can handle it.
Unlike the HD 5970 which had the fan located on the far end of the PCB, the HD 6990 keeps things cool with the fan smack in the middle of the two GPUs. Speaking of pairs, the HD 6990 comes with a Dual BIOS switch which allows end-users to fiddle around with the settings of the HD 6990 and customize performance to their liking. That would be set to switch 1, at switch 2 the HD 6990 runs at factory default settings and these cannot be changed. Of course, one can still use software (such as MSI Afterburner) to increase factory speeds and overclock the card.
The HD 6990 is obviously designed with big resolutions in mind, as such, AMD’s Eyefinity display setup was at the core of the HD 6990′s design. It’s no surprise to see that the card has four mini-DisplayPorts 1.2 outputs along with a dual DVI port at the back. DisplayPort 1.2 not only allows for higher bandwidth and thus higher resolutions, but also stereoscopic 3D for those who have 120Hz monitors.
