Sorry, when I say "version of CUDA" I meant "whatever the hell they have on AMD" :) Last I heard CUDA will outperform OpenCL on nVidia vs AMD at the same price

Last I heard CUDA will outperform OpenCL on nVidia vs AMD at the same price point generally as a result of CUDA being in house and closer to hardware. As a result if you just care about compute performance you would go nVidia. If AMD offered their own Mantle based compute offering it would probably shift the other way.
- wmobit 12y agoThere isn't really anything fundamentally that would make CUDA faster that OpenCL. There aren't any huge semantic differences between them.
- liuliu 12y agoThe computing model, no, not really anything fundamentally different. It comes to tooling and profiling under Linux. Also, NVidia has slightly beefer cores and fewer ones, where as AMD has more cores (as I heard). Thus, for me, CUDA is a more complete tool-chain with proper compiler (nvcc), profiler (nvprof, nvvp) and libraries (cublas, cudnn, cufft).
- wmobit 12y agoThere is an OpenCL profiler for AMD, and library equivalents for those in clBLAS / clFFT
- seanmcdirmid 12y agoIs there a a comparable of cuBLAS for OpenCL?
