In just a few days from now, AMD is expected to unveil its next-generation graphics cards in the Radeon HD 7900 series and recently a company slide that compares the performance of this GPU with Nvidia’s GTX 580 was just leaked online.
The slide details the performance of the Radeon HD 7970 in 11 popular titles including Crysis 2, Metro 2033 and Civilization 5 and in all of these games, the AMD card gets past its counterpart without any difficulty.
In fact, the performance gain of the HD 7970 in comparison with the GTX 580 can be as high as 60% in games such as BattleForge, Civilization and Shogun 2, while the smallest difference is recorded in AvP where the AMD GPU surpasses its competitor by a little less than 30%.
All the tests published in the AMD slide and published on the Tweakers.net forums were run at 2560x1600 with various levels of Anti-Aliasing and Anisotropic-Filtering thrown in.
For those of you in need of a quick refresher you should know that the Radeon HD 7970 is based on the Tahiti XT core and a recent leak revealed that it would feature 32 Compute Units, for a total of 2048 streaming cores, 128 texture units, 32 ROPs and a 384-bit wide memory bus.
This will be connected to 3GB of GDDR VRAM working at 1.37GHz (5.5GHz effective), while the GPU will be clocked at 925MHz.
The AMD graphics card will get its power through a 6-pin and an 8-pin connector and the load TDP of the Radeon HD 7970 is rated at 300W while the idle board power is rated at an incredibly low 3W thanks to AMD’s ZeroCore technology.
AMD’s Radeon HD 7970 is expected to be announced on December 22, so we don’t have that much time to wait until we can see if the figures included in this leaked slide are actually true.
