> Firestorm Cores use less than 4 watts each.

This is just not true. A mini going from idle to a full single-core load is a power increase of 6W. A heavy multicore load hits over 25W.

> A 16 firestorm core Mx will produce roughly the same multicore performance as your TR

With what fantasy math? 30% faster single core performance would be 16 * 1.3 = ~21 equivalent TR cores. It'd be less than half the performance of a 64 core ThreadRipper.

M1's single-core performance is very strong. But not enough to overcome a ~2x or greater core deficit, either, not at all.



On-die memory is pretty much their one ace in the hole that nobody else will have the guts to match. Intel can't because their fabs are behind, and AMD probably doesn't have the resources to fork their architectures and/or piss off the server integrators.

I can't live without 64GB in my desktop and would love to have more, so the new Macs are not for me.


M1 isn't using on-die memory[1]. It's on-package, and likely little more than just off-the-shelf Micron or Samsung dram modules that are just soldered instead of socketed.

Thanks for the correction, that's a big difference. Still a severe limit but seems more hopeful for larger options in the future.
