OpenCL vs. CUDA/STREAM Benchmarks

AMD has focused on the open standard, cross-platform OpenCL standard for GPU-Compute functionality with support for acceleration on both GPUs and CPUs (including embedded and hand-held devices).  OpenCL allows the GPU to help the CPU do the computing or data crunching, to enable faster and more efficient processing.

SiSoftware has posted OpenCL benchmarks for GPU based acceleration and compared it to both CUDA and ATI Stream. 

Using the latest OpenCL 1.0 Beta 4, the benchmarks show great results: performance parity with CUDA (in some cases OpenCL is faster) and 50% faster than native CAL/STREAM.

The take away conclusion: There is no reason not to port CUDA code to OpenCL now!
