NVIDIA GeForce GTX 770 Review - GK104 Speed Bump
3DMark, 3DMark11, Unigine Heaven - SLI
For 3DMark11 adding in a second GTX 770 results in a 93% scale rate and a win over both the GTX 680 SLI and HD 7970 GHz Edition CrossFire scores.
Despite an 88% scaling rate on the standard and extreme presets by adding in a second GTX 770 card, the AMD CrossFire solution still produces a better score in latest version of 3DMark.
On Unigine Heaven, the GTX 770 cards in SLI do run a bit faster than the HD 7970s in CrossFire, 9.7% at the Extreme tessellation levels.
