Except it didn't. The 9900K was in a completely different performance category from the M1 in these dolphin tests. To compare efficiency you need to control for performance. What Dolphin did here would be like trying to compare CPU coolers without controlling for power consumption. What makes the M1 impressive is its performance relative to other CPUs in its power category (eg, the M1 vs. the i7-1185G7 in this chart: https://images.anandtech.com/graphs/graph16680/117493.png https://images.anandtech.com/graphs/graph16680/117493.png ), or when it manages to be both faster and use less power. That's impressive. But using less power while also being significantly slower (which is what Dolphin's comparison is saying)? That's... not impressive or interesting. That's some "no shit sherlock" level stuff - just compare literally any mobile CPU from Intel or AMD vs. the desktop equivalent in the same generation. You'll see a chart that looks basically the same, with the mobile CPU many times more power efficient while also being a lot slower. Especially when you're taking the top-end desktop CPU for the comparison, the CPU where power efficiency isn't even remotely a design goal.
