I'm not going to do that again. The 204GB/s number thrown around by ms is completely bogus (and probably corresponds to creative accounting for some rmw cycles inside the gpu caches). At this time, I stick with a maximum achievable bandwidth of approx. 150 GB/s (for some peculair access patterns). Until a REAL ms engineer comes forth and explains the REAL functions of the gpu crossbar, we should take the numbers forwarded by ms pr speak as rumours (or extremely creative accounting). |
