Thats relieving!

I'm starting to believe in Qualcomm! The Snapdragon X2 Elite Extreme is alas only available in a single system, with it's tri-channel on-package (!) memory good for 228 GB/s. But it's a beast. The core is just good, even in the mainstream form in other systems: some of the best single core performance you can get, shy of Apple.

And they are upstreaming their stuff much better! They hired a bunch of really good known FOSS developers and it seems to be working!

Now they are talking up High Bandwidth Compute as their next big thing. And I want to believe, even if it makes me nervous that they too intend to leave consumer computing completely in the dust. https://www.qualcomm.com/news/onq/2026/11/qualcomm-hbc-valid...

This is, as commented, at M4 Max levels of GB/s. It is not impressive. It has some uses! But if this was their modern opening salvo I would not be impressed.

Why is on-package memory impressive/better in this case? It's one channel more than your typical consumer x86 system (192-bit bus vs 128-bit) which is something but you could technically have quad channel with two LPCAMM2 sockets?
