I test two borrowed nvidia CMP 90HX GA102-100 Ampere mining graphics cards, very similar in configuration to an RTX 3080 10GB. Unfortunately the memory wont unlock beyond some offsets, meaning the card really is only suitable for memory hard mining algorithms like ETChash and Autolykos.

65 sols - 174W FLUX
648 MH/s - 198W KAS
30 MH/s - 184W KawPow
90MH - 200W ETChash
