Why does the GPGPU benchmark show Memory Read/Write results so much lower than the x64 CPU?

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.

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.
