WebApr 2, 2024 · we can estimate L2 bandwidth as: 2*64*2MB/123us = 2.08TB/s Both of these are rough measurements (I'm not doing careful benchmarking here), but bandwidthTest on this V100 GPU reports a device memory bandwidth of ~700GB/s, so I believe the 600GB/s number is "in the ballpark". WebOct 25, 2011 · You do ~32GB of global memory accesses where the bandwidth will be given by the current threads running (reading) in the SMs and the size of the data read. All accesses in global memory are cached in L1 and L2 unless you specify un-cached data to the compiler. I think so. Achieved bandwidth is related to global memory.
