3DMark 11 is the latest version of the world's most popular benchmark. Designed to measure your PC's gaming performance 3DMark 11 makes extensive use of all the new features in DirectX 11 including tessellation, compute shaders and multi-threading. Trusted by gamers worldwide to give accurate and unbiased results, 3DMark 11 is the best way to consistently and reliably test DirectX 11 under game-like loads.
Starting off with 3DMark 11 we can see that performance between the new GTX 660 and the older GTX 580 is near identical.
Against the AMD side of things you can see we're sitting around HD 7950 level performance. Of course 3DMark 11 isn't always the best to gauge a whole model off, but it helps create a good benchmark of what we're expecting to see.
Let's see if we continue to sit around GTX 580 numbers as we continue on with our benchmarks.
