Sapphire HD7990 QuadFireX Review

We decided to crank the image quality within Dirt ShowDown, as all cards produced such smooth frame rates on the last page. The results between AMD and NVIDIA cards on this page are not directly comparable as both companies use different algorithms for these settings. It is interesting however to measure frame rate performance when increasing the anti aliasing settings.
We enabled the 8f16x EQAA setting for the AMD HD7990 Malta and 16 X QCSAA for the GTX 690 and Titan.

Crossfire scaling is excellent, averaging 144 frames per second with two HD7990’s in QuadFire.
