Benchmarks Real world tests of GeForce GTX 770M vs 670

Passmark Industry standard benchmark for overall graphics card performance

I thought it might also be interesting to run the new 3DMark on these GPUs and the results show a similar story to the gaming tests on the previous page.

3DMark 11 Graphics Industry standard benchmark that tests DirectX 11 GPU performance

3DMark11 puts the GTX 770 slightly ahead of both the GTX 680 and the Radeon HD 7970 - an edge of 11% over the AMD offering.

3DMark Vantage Graphics Industry standard benchmark that tests DirectX 10 GPU performance

Besides the above slide, NVIDIA provided some performance estimates using results from the 3DMark 11 Performance benchmark, and the results are even more heavily in favor of NVIDIA.

BioShock Infinite 1920 x 1080 - Ultra preset + DX11 (DDOF)

GeForce GTX 770M
29.43 fps
GeForce GTX 670
83.7 fps
Being able to play top titles like Metro Last Light, Bioshock Infinite and Sleeping Dogs at these quality settings and at 1920x1080 resolution was impressive.

Crysis 3 1920 x 1080 - Very High preset + 16xAF + 2xSMAA

GeForce GTX 770M
19.55 fps
GeForce GTX 670
59.9 fps
As of eight days ago the Radeon HD 7970 GHz Edition will come with four games: Crysis 3, Bioshock Infinite, Tomb Raider and Far Cry 3: Blood Dragon.
