Just a few more hours are left until AMD makes official the Radeon HD 7970, but for those of you not wanting to wait for the first reviews of the card to arrive you can now check out AMD’s own benchmarks for this GPU, which were just recently leaked on the Web.
The results are taken straight out of AMD’s “Benchmarking Guide” for the HD 7970 that is provided to receivers together with their test sample, and cover the performance of the card both in single and in CrossFireX setups.
This is then compared with the results achieved by the previous generation HD 6970 as well as to those of Nvidia’s GTX 580.
Needless to say, the Radeon HD 7970 comes out on top in all of these tests and even manages to provide palyable frame rates in the HD3D mode at 1080p resolution.
We have included some of these results in this article, but more at available here, where they have been uploaded by a user from the XtremeSystmes forum.
Even more impressive than the single-GPU performance of the HD 7970 is the CrossFireX scaling that AMD says its card can achieve, many titles showing a dual-GPU setup as being nearly two times faster than a single HD 7970.
AMD’s Radeon HD 7970 is based on the Tahiti XT core which is built using the company’s new Graphics Core Next (GCN) architecture designed specifically to improve the compute performance of its cards.
This GPU includes 32 Compute Units, for a total of 2048 streaming cores, 128 texture units, 32 ROPs and a 384-bit wide memory bus which is linked to 3GB of video buffer working at 1.37GHz (5.5GHz effective). The GPU is clocked at 925MHz.
AMD is expected to make official the graphics card on December 22, with availability being scheduled for January 2012.
