"Adamantine" L4 Cache Confirmed on Intel "Meteor Lake," Acts as a Passive Interposer
We've known from a recent report that "Meteor Lake" introduces an L4 cache, and now we are learning that it is codenamed "Adamantine," and serves functions resembling that of a passive interposer. Intel's upcoming "Meteor Lake" microarchitecture will power the company's first disaggregated processor for the client segment.
A disaggregated processor is different from an MCM (such as "Clarkdale"), since finer components that make up the processor that otherwise can't exist on their own packages without extreme latency, are made to share a single package via a high-speed interconnect. This disaggregation is purely for economic reasons, so the company needn't use the latest (and most expensive) foundry node for the entire processor, but ration it to the specific components that benefit the most from it. Unlike AMD client processors that disaggregate the CPU cores and the remaining processor I/O into two kinds of chiplets, Intel "Meteor Lake" will see the breaking up of not just CPU cores (compute tile), but also the iGPU on its own tile, besides the platform I/O on separate tiles still.
