Intel is already there at the ultra-high-end, the Xeon Max is a hybrid with 64GB of HBM2 on-package and an external DDR5 bus supporting up to 4TB of socketed RAM. The HBM2 can be configured to work as L4 cache for the DDR5, or it can boot without any DDR5 at all and run entirely from the HBM2.

- bryanlarsen 3y agoMI300X also has on-package RAM, but that's even further from a laptop chip than Xeon Max. :)
- jauntywundrkind 3y agoIntel's Lakefield also comes to mind, pretty underrated chip imo. The first x86 big/small heterogenous chip, using Intel's Foveros to stack memory, CPU, and platform chip into one package. It made for a very simple design that just needed power. LPDDR4X-4266 doesn't crazy fast but in 2020 it was pretty swift. https://www.anandtech.com/show/15877/intel-hybrid-cpu-lakefield-all-you-need-to-know/3 https://www.anandtech.com/show/15877/intel-hybrid-cpu-lakefi... Alas the 1+4 Skylake+atom were all pretty meh chips & Intel hasn't tried again. Conceptually I really.liked it, and it was doing great against the Qualcomm 8cx competitor for the tablets/2-in-1s it was in, but people wanted more.
- bastard_op 3y agoI remember seeing this from STH as well, and my first thought was "I want one of these in my laptop!" It'd be perfect then to max ram in a laptop with 2 sodimm slots, or one of these 64gb lpcamm's. Ideally with a thinner laptop in mind, but probably not with the heatsink for THAT massive xeon. I really hope the hbm memory on-die trickles down into pro-sumer processor chips eventually too.
