The Nvidia’s GTX 980 Ti<\/a> specs position it as the saviour single-GPU for common mortals. After all, affordability and performance in balance are key factors for any upcoming graphics card gaining ground in the battle for our wallets.<\/p>\n

If AMD cannot match NVIDIA, they will fall short, and they’ve positioned their Hawaii XT as well as Hawaii Pro cards to do just that.<\/p>\n

That said, sometimes they like to go a little bonkers with their GPUs.<\/p>\n

Recently, new details regarding the AMD’s R9 390X or Fiji XT, as it more popularly known as, have surfaced. Let’s get down and dirty with these leaked details and rumours.<\/p>\n

According to\u00a0Johan Andersson<\/a>, technical director for Frostbite at EA, they have been actively testing out AMD’s new absurdly fast card. It appears the Fiji XT is using a closed-loop hybrid liquid cooling solution, keeping the card’s performance up and noise to a minimum.<\/p>\n

The card will not feature any DVI connectors, and will only have HDMI as well as DisplayPort outputs. The Fiji XT will also be a much shorter card in length than any current generation graphic cards, comparable to something from a decade ago.<\/p>\n

The Fiji XT is reported to be\u00a0based on the revamped GCN 1.3 architecture. It will integrate 4096 stream processors (64 compute units), 256 texture units and a new\u00a0memory controller.<\/p>\n

This new memory controller support vertically stacked high bandwidth memory (HBM) chips<\/a>. To sweeten the deal, the memory controller will have a 1024-bit I\/O\u00a0interface.<\/p>\n

The HBM\u00a0chips, when compared to GDDR5, are firstly stacked, and as result will have a higher bus width, bandwidth per stack and a lower voltage requirement.\u00a0The picture below, helps give more perspective on the differences:<\/p>\n
