Don’t know what LLM lens is. I had an ATI card. Miserable. Fglrx awful. I’ve tried various AMDs over the last 15 years. All total garbage compared to nvidia. Throughout this period was consistently informed of new OSS drivers blah blah. Linus says “fuck nvidia”. AMD still rubbish.
Finally, now I have 6x4090 on one machine. Just works. 1x5090 on other. Just works. And everyone I know prefers N to A. Drivers proprietary. Result great. GPU responds well.
