I don't know for sure, but these Radeon GPUs are power hungry and hot. It could be just that after multiple days the entire computer is heat soaked and goes through more thermal throttling than even the "steady state" GPU tests that most gamers do (a few hours).
It might also be cruft building up over time with small memory leaks or imperfect memory management.
- nexuist 7y agoThis is what I thought too, the heat simply becomes overwhelming and the unit has to underclock to prevent melting.
- close04 7y agoI think the "towards the end" part is the misleading one. The software has no idea where the end is or it would just jump there. Since the run took 4 days slowing down due to throttling would happen pretty fast as the card reaches a thermal equilibrium. Certainly wouldn't take days to do it. It's more likely the explanation above of something (not heat) accumulating over time and slowing down the processing.
