HD 7790 and 650 Ti BOOST Roundup: Asus, MSI, and Galaxy
Results: Luxmark 2.0
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.
I used this test on just the 3770K and not just the video cards. Some really, really interesting results here. The 7790s had outstanding performance in this benchmark. The 650 Ti BOOST? Not so much. In fact, we can almost categorize this as the ViRGE 3D of OpenCL software. It acts as a decelerator when used with a high end CPU for this particular workload.
