Results: Luxmark 2.0
I was quite curious about the OpenCL performance of these latest cards. AMD has really been pushing the compute API as of late, especially in advance of their Kaveri APU release. 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, although they are focused on their CUDA API. 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.
Well hello there, Maxwell! For quite some time the NVIDIA cards did not compare well to what AMD brought to the table with regards to Luxmark and OpenCL. I did not include the MSI 970 results as they were identical to the Zotac. We see nearly a two-fold increase in performance over the GTX 780 of the generation before, and it even overshadows the R9 290X. NVIDIA made some big improvements here with hardware and software support, and it was sorely needed!
