Why weren't crypto gpus running at 100%?
replyMost crypto mining on GPUs would use 100% of memory bandwidth, but only a fraction of the compute available. This is a consequence of ASIC resistance of their mining algorithms -- custom silicon can only offer a modest benefit over GPUs if the hard part is memory bandwidth.
replyI bought a RTX 3070 off a miner when Eth went to proof of stake.
replyIt was clean, cheap, and is still going strong for daily gaming.
In its working life it was undervolted and probably cooled better than in my rig.
