HIS HD6990 Dual CrossfireX Review

Stone Giant is a benchmark tech demo that showcases and measures DirectX 11 performance using the BitSquid Engine. This is a tessellation heavy benchmark that, traditionally, runs very well on nVidia hardware. The jump in measured tessellation performance by the Radeon HD 6990 was so surprisingly high, that we re-ran the test several times to make sure the results were accurate.

CrossfireX performance with Stone Giant is all over the place, we recorded between 240 and 260 fps with this engine. Hard to get a grip on the scaling, but regardless its interesting enough to merit an inclusion – the new AMD optimised driver setting was used with the HD6990 which would account for some of the variances. We have included a video of a run of the Stone Giant benchmark above.
