With the year being almost over, it appears that AMD is wasting no time in showing off their new 28nm PCI-E 3.0 video cards. They have already revealed the Radeon HD 7970, the flagship single GPU of the 7000 series. The specifications for this card are very impressive, and AMD even plans for a January 2012 release.
Details
The 7970 should be the first 28nm desktop GPU available, allowing for large heat and power consumption decreases clock for clock compared to the old 40nm process. This card supports many modern technologies such as DirectX 11, PCI Express 3.0 interface (backwards compatible of course), AMD Eyefinity, and 4k video with 3 GHz HDMI 1.4a and a DisplayPort 1.2 HBR2.
The 7970 will come with 3GB GDDR5 which is great for those with large resolution monitors and/or multi-monitor setups. Combined with a 384-bit memory interface and 5.5 GHz effective memory clock, the memory bandwidth for the 7970 reaches 264 GB/s. There are 32 compute units/2048 stream processors, 128 texture units, 128 Z/stencil ROPs, 32 color ROPs, and a 925 MHz core clock. Dual geometry engines and asynchronous engines are present, and the single precision compute power is a whopping 3.79 TFLOPs. Double precision compute power reaches 947 GFLOPs.
Of course the 7970 also supports CrossFire and Eyefinity - with up to six monitors in Eyefinity mode. OpenGL 4.2 is supported, as well as impressive AA options such as 24x multisample or supersample, adaptive AA, and MLAA. Unfortunately a TDP is not given. System requirements include a 500W PSU with one 8-pin PCI-E and one 6-pin PCI-E power connector, therefore power consumption is over 225W. As mentioned before, the release is scheduled for January 2012 and the release price is expected to be $549. Keep in touch for updates on more news and reviews regarding this product!
