AMD is about to take the market by storm and with NVIDIA’s GTX 690 rocking the premium dual card market for some time now there has been a big demand for an alternative, mostly of course from AMD. The HD 7990 is a powerful card and it's going to be exciting to see if its anywhere near as popular as the GTX 690, although I'm fairly certain it will be.
Gigabyte are the latest in a line of AMD partners who will be releasing an HD 7990 and they'll be kicking off this party with the launch of a dual-GPU Radeon HD 7990, the GV-R799D5-6GD-B which will take its place as Gigabytes flagship model. Based on two 28nm Tahiti GPU cores, with 4096 stream processors it certainly packs quite a performance punch.
The only downside to this card at this time however is that AMD's reference design has to be adhered to an that means the only difference between this card from Gigabyte and any other manufacturer is just going to be the sticker on the side and while there will be custom solution in the future (we hope), we don't know exactly when that will be.
With features like 4096 stream processors, a 950MHz / 1000 MHz GPU Clock / Boost Clock, 6GB of GDDR5 @ 6000 MHz and a dual 384bit memory interface on the reference card, we can only imagine what this card could be pushed to with a non-reference design in the future, but for now, it's still an incredible piece of hardware with an incredible price tag to match, with only a couple of week till its release you haven't got long to save up the £££ required for a purchase.
