Isn't that going to limit the single core to being not much higher than the original M1? Maybe with more power and cooling they can crank it up a bit, but it seems like that's the limit.

Not really sure what you're saying. Single core is pretty consistent between M1 to M1 Ultra

Yeah, talking about the pro line. If they're stuck at M1 single core speeds at desktop level it'll suck for certain applications.

Err the single core performance of the M1 chips is very high, I think when they were released they were the most powerful single cores available.

Hm, I don't see it that was at all.

If we look at how Intel chips scale, we see that single core performance actually decreases on the largest chips. That's why historically the Xeon Mac Pro would actually have a lower single core performance than the similar generation i5 or i7.

Of course the Xeon would more than make up for it by having tons of cores, more PCIe lanes, support for ECC RAM, etc.

I think it would be fantastic if the M1 Supermega or whatever they end up calling the Mac Pro chip matches the M1 single core performance.
