(Test) Incredible Performance Boost in OpenGL Tessellation With Recent Catalyst Drivers



TessMark - OpenGL tessellation

I took the advantage of the release of the new Catalyst 11.6 to re-bench my SAPPHIRE Radeon HD 6970.

And I was suprised, almost shocked by the boost in OpenGL tessellation performance brought by latest Catalyst 11.5 and 11.6. There’s a huge gap in tessellation perf between 11.4 and 11.5/11.6 and no word from AMD about this incredible performance improvement… maybe not enough newsworthy ;)

To make the story short, gains in performance are just awesome in TessMark 0.3.0: up to 100% (tessellation level of 16). In Unigine Heaven 2.1, gains are around 10% (like mentioned in Cat 11.6 release notes).

For this quick test, I compared Cat 11.4 vs Cat 11.6 (Cat11.5 and Cat11.6 give the same kind of scores). Here are the results:
