TDP is completely irrelevant in geekbench though. The whole test is designed not to termal-throttle, so an iPad cpu with 7W TDP can beat a workstation with 150W TDP (single core). On top of that, the single core performance of mobile ryzen is expected to greatly improve with zen3 (just like it did on desktop), and that's still 7nm, compared to apple 5.
Compared to Intel, M1 is truly impressive. I just ran R23 on my 1068NG7 and got 4231 multi core (at almost 30W TDP). If Intel was the only player in town, this would be well worth the hassle of migrating to different instruction set (for people like me, very significant). But it's not. Right now, for the workload that matters for me (sustained multicore performance), it seems to be at best on par with AMD. I really hope that changes with M1X.
