- smoldesu 3y agoIt fully depends on the workload. The 4090 itself draws around 450w at load, and the M2 Ultra peaks around 300w. If your workload is >1.5x faster on Nvidia hardware, then it's per-prompt efficiency probably beats out the M2 Ultra.
- frontierkodiak 3y agoNot to mention that you can trivially set a 300w power cap on the 4090 and still get 75-80% of peak FLOPS.
- datameta 3y agoAll valid points, I think I looked at it too trivially and fired an opinion from the hip.
