While Jen Hsun is almost done rehearsing his speech for GTC about Maxwell GM200, we are looking for clues about Big Maxwell’s performance.
With no surprise we found TITAN X in CompuBench database. It will probably be removed by the time most of you will see this post, so we took few screengrabs, and posted the full opencl info dump, just in case.
According to new information from CompuBench, TITAN X has 24 compute units, which basically means it has 3072 CUDA cores. The software also reports on maximum clock, in other words boost clock, of 1076 MHz.
TITAN X outperforms the competition in every benchmark. Just remember that CompuBench top list is using median value from all entries, so some cards can actually perform better (for instance, if someone is using overclocking).
I’m leaving the interpretation to you, OpenCL benchmark has no value for gamers, but some of you might still find it interesting.
