A little googling shows the S80 has (had?) really bad drivers that caused it to be outmatched by much weaker GPUs, so the 120% number isn’t as crazy as you might first expect.

Hopefully we get more competitive GPUs in the future. On paper that’s already a pretty decent card (16 GB too!)

Can someone tell me about these cards? I’ve literally never heard of them before now. Obviously they’re not big performers, but what are they like?
