Tahiti graphics chip is not just a successor only. A number of improvement as well as a variety of new features embedded AMD graphics chip upscale.

The first is of course the number of shader processors are far more than ever before, 2048 for HD 7970 and HD 1792 for 7950. Its performance is also increasingly savage with the support of a large-capacity memory and 384-bit memory interface that is wider. This is higher than predecessors and competitors are on average still 256-bit wide. In addition, there are again some improvement as well as features that are present in both series graphics cards. What are they? And what about performance when compared to other upscale graphic card? Check out our soft reviews below.

Eyefinity 2.0
