> M1 Ultra features an extraordinarily powerful 20-core CPU with 16 high-performance cores and four high-efficiency cores. It delivers 90 percent higher multi-threaded performance than the fastest available 16-core PC desktop chip in the same power envelope.
Maybe not a huge caveat, as 16-core chips in the same power envelope probably covers most of what an average PC user is going to have, but there are 64-core Threadrippers out there available for a PC (putting aside that it's entirely possible to put a server motherboard and thus a server chip in a desktop PC case).
- hoistbypetard 5y agoIs that Threadripper in anything like the "same power envelope"?
- ollien 5y agoIf I'm reading the graph in the press release right, M1 Ultra will have a TDP of 60W, right? A 3990X has a TDP of 280W. I know TDP != power draw, and that everyone calculates TDP differently, but looking purely at orders of magnitude, no, it's not even close.

- eloff 5y ago"in the same power envelope" is a pretty big caveat. Desktop chips aren't very optimized for power consumption. I'd like to see the actual performance comparison.
- adfgadfgaery 5y agoThat line is blatantly dishonest, but not for the reasons you pointed out. While the i9-12900K is a 16-core processor, it uses Intel's version of big.LITTLE. Eight of its 16 cores are relatively low performance 'E' cores. This means it has only half the performance cores of the M1 Ultra, yet it achieves 3/4 of the performance by Apple's own graphic. Alder Lake has been repeatedly shown to outperform M1 core-per-core. The M1 Ultra is just way bigger. (And way more power efficient, which is a tremendous achievement for laptops but irrelevant for desktops.)
