SiSoftware have release Sandra 2010 benchmark suite with OpenCL support (adding to the CUDA and Stream/CTM support found in Sandra 2009).  SiSoftware have also added DirectX11 Compute Shader support to be the first benchmark utility that allows you to compare basic computational and bandwidth performance across a wide range of programming interfaces and also now across multiple vendor platforms.

The development was undertaken in collaboration with AMD who have the first CPU + GPU OpenCL implementation and provides an interesting chance to compare and contrast performance of CPUs and GPUs on the same workloads.
