Radeon VII on a mining-like bench

Viliam Furik · 2021-01-12, 20:35

A few minutes ago, I have successfully installed Radeon VII on a handmade cardboard bench (see the picture in the next post). It is running nicely, only a tad slower than directly in the motherboard, with good temps because it's now on open air.

AliExpress can do wonders

I was told I should post numbers, so here they are:

Exponent = 106M

In motherboard in case:
960 us/it
GEC 0.45 s
95 °C

On bench:
985 us/it
GEC 0.51 s
80 °C

Time to install Linux. Your goal should be in the neighborhood of 700us

Install Linux for a gain of 260 microseconds? Unless a person cut their OS teeth on Linux, there is not much to gain.

If it's possible to run it through a VM, I might give it a try someday.

260/960 = 27% faster. I call that pretty significant.

I'm curious - does the same applies to PRP? Namely, are there any notable performance gains from using mprime instead of prime95 on LL/PRP tests?

I have never noticed much speed difference when using GWNUM programs under different operating systems.

There is a few percent to gain in throughput by running two instances of gpuOwl.

Thanks for letting us know.

960/700 = 1.37 which means 37% faster (more thruput).
