I was quite curious about the OpenCL performance of these latest cards.  AMD has really been pushing OpenCL as of late, especially in advance of the release of the Kaveri APUs.  They have a pretty solid OpenCL 1.2 implementation for their GCN based chips.  NVIDIA of course has been blowing the GPGPU horn as loudly as possible over the years and focused on CUDA.  Oddly enough, Kepler made compute performance take a back seat to enable better performance and efficiency in graphics applications.  I used the 64 bit version of Luxmark 2.0 with the Sala test.

In this particular GPGPU benchmark the latest Kepler cores fare pretty poorly as compared to AMD’s GCN architecture.  The 270X is about 50% faster while the 280X is easily double that of the GTX 760.
