Your system RAM is probably 1/20th the VRAM bandwidth of the 5090 (way way less than half) unless you're running a workstation board with quad or 8 channel RAM, then it's only about 1/10th or 1/5th respectively.

I'm saying its less than half of this DGX Spark: dual channel DDR5-6000 vs quad channel LPDDR5-8000.
