Linux OpenCL Performance: ATI vs NVIDIA

Recently we provided the first Linux-based review of the NVIDIA GeForce GTX 460 graphics card. Overall, this Fermi-based graphics card was a great performer for selling around $200 USD and is complemented by great video playback capabilities with VDPAU acceleration and great proprietary driver support. In that review we primarily looked at the OpenGL performance under Linux, but with NVIDIA's Fermi architecture bringing great GPGPU advancements for CUDA and OpenCL users too, in this article we are looking more closely at the Open Computing
Language performance of this GF104 graphics card as well as other NVIDIA and ATI graphics cards.

Found in Phoronix Test Suite 2.8 "Torsken" is an OpenCL test suite with a number of new OpenCL test profiles. These initial Open Computing Language benchmarks include Julia GPU, Mandel GPU, SmallPT GPU, Mandelbulb GPU, and Gluxmark, which follows a Python OpenCL benchmark previously integrated into our advanced software-testing platform. For those now running these benchmarks and looking for numbers to compare for reference to see how your system stacks up with regard to its OpenCL capabilities or you are interested in seeing how the ATI and NVIDIA OpenCL performance under Linux compares, these results are for you...
