There are six tests in 3DMark 11. The four graphics tests use advanced rendering techniques to compile the scene including tessellation, volumetric lighting, depth of field and post processing effects. The physics test uses rigid body simulation to stress the CPU while the combined test features CPU and GPU workloads. The CPU handles rigid-body physics while the GPU is tasked with volumetric lighting, tessellation, post processing as well as simulating soft-body physics using DirectCompute.

Here we have our first role reversal. The switch isn't by a huge margin so could be drivers or memory bandwidth. For instance in 3DMark 11 scores are improved with core speed whereas Firestire responds better to memory adjustments.
