The results of our tests are hardly surprising. The GeForce GTX 570 SLI tandem has colossal hardware resources and can cope with almost any existing game at any resolution. The only exceptions are the notorious Crysis Warhead at 2560x1600 and Metro 2033 with its wide fluctuations of speed with enabled tessellation. The Radeon HD 5970 has no chance, of course, but it is going to be soon succeeded by the Radeon HD 6990. Besides, premium-class multi-GPU solutions are often overkill for today’s multiplatform projects. Costly and less easy to manage, they do not bring any tangible improvements over top-end single-GPU cards.
Thus, Nvidia’s refusal to release a dual-GF100 or dual-GF104 product makes sense. Developing and producing such a graphics card would not be an easy matter. It would have a high manufacturing cost and price, so its popularity wouldn't be high. Such luxurious graphics cards account for but a negligible share of the total sales just because demanding gamers can be perfectly satisfied by a single GeForce GTX 580. However, Nvidia may want to respond to AMD’s upcoming Radeon HD 6990, so we may see another fight of dual-processor monsters yet.
3DMark11 was the only test where we had problems with our GeForce GTX 570 SLI tandem. Its performance is best illustrated by the summary diagrams:
It is at resolutions of 1920x1080 and higher that such solutions are expected to show their best. The most popular resolution is 2560x1600 although some large-screen modern monitors with an aspect rate of 16:9 have a native resolution of 2560x1440 (WQHD) or 2048x1152 (QWXGA) pixels. In the highest display mode the GeForce GTX 570 SLI is an average 42-43% ahead of the single GeForce GTX 580 and Radeon HD 5970. The performance scalability relative to the single GTX 570 card is 69% on average, but the overall number if spoiled by Fallout: New Vegas and 3DMark11. In some games the SLI scalability is actually as high as 90 to 100%. The notorious Crysis Warhead is the only game the GeForce GTX 570 SLI tandem could not make playable at 2560x1600. So, this SLI configuration is indeed extremely fast but we don't know if the hypothetic dual-chip GeForce GTX 590 is going to have the same specs and if it will be competitive to a Radeon HD 6970 CrossFire tandem or to the upcoming Radeon HD 6990.
