AMD Radeon HD 6990 – More details released

[FONT=Tahoma]The AMD Radeon HD 6990, likely to be one of the most powerful GPU’s released in the first Quarter of 2011, will have 2 Cayman GPU’s. The card also features 3072 stream processors and a nice 4GB of memory. They also use a dual 256-bit memory interface, allowing huge bandwidth.[/FONT]

The card has a dual-slot cooler with a centrally-placed blower fan. There are of course two GPU’s and so the fan is placed in-between these processors linked by vapour-chamber based heatsinks for powerful cooling. It is likely the card will have two 8-pin power connectors but one of these may be a 6-pin.

]I hear you ask, what about Crossfire. Well, lets be honest, it does already have two GPU’s with the combined power of two high-end single GPU’s, so why would you need the CrossFire set-up? Well, just in case you do have a good reason and want some quad-GPU fun then it does feature a single CrossfireX connector.

The more intriguing part of this design, is that the backplate only features one DVI port, it does also contain four mini DisplayPort outputs. This is slightly annoying as you are likely to need adaptors to use your current monitors; however rumour has it that this could provide support for up to 12 monitors.

We must also point out that this card is really quite long, roughly 300mm long in fact (A4 paper size is 297mm). Currently we are only guessing at prices but it is likely to go over the US $500 (Over £300). Of course this is the only rival to NVIDIA’s GTX 580 flagship, so it will be interesting to see if its priced just under and how well it does perform.
