18:32:49 Ryzen 7950X running at 0.85V, 4.3 GHz all core: 18143 h/s, 140 watts at the wall = 129.6 h/J 18:33:01 and I could shave off another 10 watts if I removed GPU 18:33:31 so 140 h/J is possible for headless systems 18:36:48 and maybe up to 150 h/J with curve optimizer 18:52:14 Definitely needed, since the breakeven efficiency is around 100 H/J these days
