Intel "Meteor Lake-P" SoC with 6P+8E Compute Tile Pictured
Intel's next-generation "Meteor Lake-P" mobile processor with a 6P+8E Compute Tile was shown off at the 2022 IEEE VLSI Symposium on Tech and Circuits (6 performance cores and 8 efficiency cores). We now have annotations for all four tiles, as well as a close-up die-shot of the Compute Tile. Intel also confirmed that the Compute Tile will be built on its homebrew Intel 4 silicon fabrication process, which offers over 20% iso-power performance increase versus the Intel 7 node, through extensive use of EUV lithography.
We had earlier seen a 2P+8E version of the "Meteor Lake" Compute Tile, probably from the "Meteor Lake-U" package. The larger 6P+8E Compute tile features six "Redwood Cove" performance cores, and two "Crestmont" efficiency core clusters, each with four E-cores. Assuming the L3 cache slice per P-core or E-core cluster is 2.5 MB, there has to be 20 MB of L3 cache on the compute tile. Each P-core has 2 MB of dedicated L2 cache, while each of the two E-core clusters shares 4 MB of L2 cache among four E-cores.
