Status of RX5700XT tests #67

Closed valeriob01 closed 4 years ago

valeriob01 commented 5 years ago

Now that the firmware files are in place, finally the GPU is working. The Radeon RX5700XT does not work with gpuOwl for doing PRP, but works with Mfakto for doing Trial Factoring. GpuOwl doing PRP always gives error (EE lines) and after 3 consecutive errors it quits.

I have seen that someone is asking for RX5700 benchmarks on the forum. For Trial Factoring 191M-193M from 73 to 74, it takes 20 minutes. The Vega64 performs better.

Thank you, you could post the benchmark results on the forum, I assume they would be easier to find there.

I don't know the cause of the always-error on RX5700, that is not expected; OTOH I have no way of testing and no plan to aquire this generation of GPUs (because they seem weak on FP64, compared to R7); closing because no action.

for some obscure reason I can't write in the forum as my account has disappeared. Can you do it please?

I could send you my gpu for testing.

Ok, I know the newer generation of AMD gpus is called Arcturus, it is probably a Vega-based professional gpu, and faster than a Radeon Instinct MI60, that is the board to wait for.

if not willing to wait, right now one can buy the Titan V, expensive, but worth.
