WebMay 22, 2012 · It’s not high as a ddr memory. DDR memory latency is always high as there is a lot of overhead to reading a memory line. CPUs have larger caches and lower parallelism to compensate. GPU depends on latency hiding rather than large caches so you need to allow it to work. WebIn general though GPUs are designed as a throughput architecture which means that by creating enough threads the latency to the memories, including the global memory, is …
WebMemory latencyis the time (the latency) between initiating a request for a byteor word in memory until it is retrieved by a processor.

GDRCopy … WebImproves bandwidth but also adds latency. GPU Memory System GPU Memory accesses measured at VE: Sustained fabric bandwidth ~90% of peak GPU cache hit ~150 cycles, cache miss ~300 cycles. TLB miss adds 50-150 cycles GPU cache line read after write to same cache line adds ~30 cycles
WebIn the dynamic latency analysis, we used a GPU perfor-mance simulator and an exemplary workload to determine two key contributors to dynamic memory load latency, queueing and arbitration. Lastly, we showed that latency is performance-critical for this particular workload, even though the architec-ture it is running on is a throughput architecture.
