MAA Posted July 7, 2023 Share Posted July 7, 2023 Hello, Why does the GPGPU benchmark show Memory Read/Write results so much lower than the x64 CPU? The iGPU is located on the same chip as the Memory Controller and CPU, and should show the same read/write speed. Quote Link to comment Share on other sites More sharing options...

Probably it's because there's a bottleneck between the iGPU compute units and CPU cores in terms of how fast it can transfer data back and forth.

MAA Posted July 7, 2023 Author Share Posted July 7, 2023 This is a speed test between iGPU cores and memory. How are the x64 CPU cores involved? And what do you mean by "bottleneck" in terms of hardware architecture? Quote Link to comment Share on other sites More sharing options...
