A slide that appears to be a part of press pack for the HD 7900 series has leaked online. The slide looks pretty legit and gives a detailed specs that were rumoured earlier.
As noted, the new HD 7970 is based on GCN architecture, features 32 CUs and 2048 ALUs. The card works at 925MHz for the GPU and features 3GB of GDDR5 memory clocked at 5.5GHz and paired up with a 384-bit memory interface. According to the slide, it packs 32 ROPs and 128 texture units. The most surprising detail from the slide is the idle board power that is set at below 3W. The max board power is at below 300W thus the card need 8-pin and 6-pin PCI-E power connectors. The card will pack one DVI, two mini DisplayPort and HDMI outputs.
The slide might be fake but for now all the details seem pretty correct considering what we have heard from our sources and various rumours. The NDA date is set at January 9th 2012.
Credits go to OBR-hardware site for leaking this one.
