We’ll be evaluating the new Radeon HD 6990 with our X58 testbed which has the following specifications:
The Radeon HD 6990 will be pitted against the current crop of high-end graphics card. We wanted to see just how much faster it will be compared to the AMD’s previous dual-GPU card, the Radeon HD 5970. We also wanted to know how it’ll match up against two Radeon HD 6970 cards in CrossFireX configuration, but unfortunately, our cards refused to CrossFire properly (quite likely due to difference in video BIOS) as it would crash whenever we tried running any benchmarks. So the results for this configuration were based on an older set of cards and drivers where we managed to run this configuration successfully.
Against NVIDIA, we have included results of their two fastest and most powerful cards, the 512 CUDA cores GeForce GTX 580 and the less powerful GeForce GTX 570, and also that of two GeForce GTX 570 cards in SLI. The GeForce GTX 580 in SLI mode is missing from our comparison due to limited availability of test cards.
