Le Comptoir du Hardware scored a die-shot of a 2P+8E core variant of the "Meteor Lake" compute tile, and Locuza annotated it. "Meteor Lake" will be Intel’s first processor to implement the company’s IDM 2.0 strategy to the fullest. The processor is a multi-chip module of various tiles (chiplets), each with a certain function, sitting on die made on a silicon fabrication node most suitable to that function. Under this strategy, for example, if Intel’s chip-designers calculate that the iGPU will be the most power-hungry component on the processor, followed by the CPU cores, the graphics tile will be built on a more advanced process than the compute tile. Intel’s "Meteor Lake" and "Arrow Lake" processors will implement chiplets built on the Intel 4, TSMC N3, and Intel 20A fabrication nodes, each with unique power and transistor-density characteristics. Learn more about the "Meteor Lake" MCM in our older article.

The 2P+8E (2 performance cores + 8 efficiency cores) compute tile is one among many variants of compute tiles Intel will develop for the various SKUs making up the next-generation Core mobile processor series. The die is annotated with the two large "Redwood Cove" P-cores and their cache slices taking up about 35% of the die area; and the two "Crestmount" E-core clusters (each with 4 E-cores), and their cache slices, taking up the rest. The two P-cores and two E-core clusters are interconnected by a Ring Bus, and share an L3 cache. The size of each L3 cache slice is either 2.5 MB or 3 MB. At 2.5 MB, the total L3 cache will be 10 MB, and at 3 MB, it will be 12 MB. As with all past generations, the L3 cache is fully accessible by all CPU cores in the compute tile.
