> Could we expand this to memory, having some soldered (on-chip?) high-speed memory, and then slots for additional slower, yet faster then the alternatives, DIMMs? Intel's already doing that with Xeon Max, it has both onboard HBM and an outboard DDR5 interface. It can be configured to run entirely from HBM with no DDR5 installed at all, or use the HBM as a huge cache in front of the DDR5, or to map the HBM and DDR5 into different memory regions to let software decide how to use each. I don't think there's been any indication of that approach filtering down to consumer architectures though, Intel is talking about doing RAM-on-package there but without any outboard memory interface alongside it. |
