Its not about the bandwidth its about the speed.
Suraj (TL Developer) did mention that PCI-E speed does matter a lot.
VEAI is a random workload (you don’t know whats coming next) so the speed how fast your data is send from the cpu to the gpu does matter a lot.
And most of the time People speak about how PCI-E does matter in Gaming.
I don’t know anyone who did test PCI-E Speed for compute.
“maybe” i will test it today (later), i just need to change link speed in bios, thats easy.
Just to check if i’m wrong.
