Performance Review of AMD Radeon HD 6990 and Radeon HD 6970 Tandem
17 May 2011
Summary: Each of us at least once in our lives thought while driving a car or even operating a kitchen appliance: imagine how good it could be if it had more power. Now let’s move to the world of computer electronics: are you happy with your Radeon HD 6970? This is a truly respectful product, but is it powerful enough to deliver you the performance you need? And what if we added a Radeon HD 6990 to that? Read our review to find out!
Pros: One of the fastest stand-alone graphics cards in the market;, Wide range of supported FSAA modes;, Best quality of anisotropic filtering in the industry;, Supports up to 6 monitors;, Fully-fledged hardware HD video decoding, including DivX and 3D;, High-quality HD video post-processing with scalability;, Integrated sound core with HD support;, Sound over HDMI;, HDMI 1.4a;, DisplayPort 1.2;, Acrive DisplayPort 1.2 adapter.
Cons: High price;, Large size;, Noticeable noise in 3D mode;, Low energy-efficiency;, Very driver-dependent performance;, Supports less GPGPU-accelerated software than the competitors.
Summary: After further testing the Radeon HD 6990 we are happy to see such a large difference in performance compared to the GeForce GTX 580. The reason being is due to price, a GeForce GTX 580 is still
online. The Radeon HD 6990 is over $200 more, at
currently. However, that $200 really is buying you a lot more performance. Sure, you can put in another GTX 580, but that combo is going to cost you $1000!
Summary: We further examine the performance of the AMD Radeon HD 6990 video card. This time comparing it to a GeForce GTX 580 and Radeon HD 6970 and Radeon HD 6970 CrossFireX on a single display. We will also look at the performance advantages of the overclock BIOS option and examine overclocking in both modes.

AMD Radeon HD 6990 Review: Sumptuous Dual-GPU Power
10 March 2011
Summary: In terms of performance, we had a rough idea of what to expect based on the specifications AMD had sent to us with weeks of anticipation. What we have here is a pair of slightly diluted Radeon HD 6970 GPUs squeezed onto a single PCB. With core clock speeds reduced by 6% and the memory frequency lowered by 9%, on average the Radeon HD 6990 was 6% slower than two Radeon HD 6970 Crossfire graphics cards.
