Just Cause 2

We like this game a lot. Keeping things comparable, NVIDIA-specific features such as the Bokeh filter and GPU water rendering are turned off.

Percentage faster/slower
than HD 6790
HD 5770 GTX 550 Ti GTX 460 1GB HD 6850
-8.6% -2.4% 26.3% 34.2%

And the ROP reduction and associated performance penalties are all too evident in Just Cause 2.

By the way, if you're wondering why the Sapphire card is consistently slower than the reference it seems as if AMD is using either tighter timings or a different timing crystal - the frequencies are the same.

A constricted architecture leads to GTX 550 Ti-matching performance, then.
