P40's + MI50's + RPC on 550B Nemotron Ultra Q3_S

Reddit r/LocalLLaMA News

Summary

User shares benchmark results running the 550B Nemotron Ultra model across two machines using RPC, achieving impressive throughput on older AMD MI50 and Nvidia P40 GPUs.

Hey guys, I went ahead and installed a 100Gbe NIC card on both my MI50 machine and my P40 machine and loaded Nemotron Ultra IQ3_S across both machines. I was pretty surprised on the throughput for such old hardware. Given the results - I now have my sights on purchasing the Chinese 22GB RTX 2080 Ti's to append more VRAM to the build and continue comparing/contrasting/experimenting.
