Radeon HD 7970 is a High-End Graphics Card based on the Graphics Core Next (GCN) Architecture.
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.
It equips a GPU Codenamed Tahiti XT which has 32 Compute Units activated and thus offers 2048 Shader Processing Units, 128 TMUs and 32 ROPs. The Central Unit is clocked at 925MHz.
The GPU accesses a 3GB frame buffer of fast GDDR5, through a 384-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 1375MHz.
With a rated board TDP of 275W, it requires at least a 600W PSU with one available 6-pin and one available 8-pin connectors.
Radeon HD 7950 used to compete with GeForce GTX 680 but its performance was even behind the lower positioned GeForce GTX 670 and was later replaced by a faster Radeon HD 7970 GHz Edition.
Radeon HD 7970 is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor (Intel Core i5 Quad Core/AMD FX Six Core) and 8GB of RAM for Optimal Performance.
i have an OCed 7950, at 1025/1375MHz(the OC that i use for gaming) it matches stock 7970(even surpass) on most benchmarks and games, i wonder what a OCed 7970 can do…
my gpu 7% better
bought 2 xfx r7970 for 150 euro's is this a good deal ? and will these cards still perform good in 2016 ?
Definitely getting this gpu, kills the gtx 780, isnt as good as a 980 but still performs amazingly today.
i cancelled my plan to buy gtx 590
i am going to buy hd 7970
Hi guys, would this bottleneck with i3 4170?
Is anyone heve problem with overheating main jump to 75-80 when playing. Is this normal for this card?
My PSU is http://www.game-debate.com/psu/index.php?ps_id=266&psu=Inter-Tech%20SL-700%20700W
Will my CPU bottle neck this card?
Would I be able to run this on a 620W PSU (Seasonic S1211)?
