A leaked Intel Meteor Lake mobile platform diagram gives us an overview of what we may expect from the 14th Gen Core processors. Out of everything mentioned in this diagram, the most interesting is the introduction of low-power E-cores and Xe-LPG iGPUs with up to 128EUs.
The information in the diagram shared by Igor'sLAB matches many of the rumours we've been reading about Meteor Lake. Besides confirmation of Meteor Lake-H, -P, and -U series chips, the diagram also shows the new processors will support DDR5-5600 (up to 96GB) and LPDDR5/5x-7467 memory (up to 64GB), PCIe 5.0 (8x lanes exclusive to Meteor Lake-H), USB4, and Thunderbolt 4. Moreover, Meteor Lake-H and -P should feature up to 14 cores (6x E-cores and 8x P-cores), while the Meteor Lake-U may be limited to 12 cores (likely 6+6).
The leak also shows a new Intel Xe-LPG graphics architecture based on Xe 2, featuring up to 128 EUs, and the addition of (up to?) two low-power E-cores. As per Raichu (via VideoCardz), these cores are on the SoC tile, contrary to the P- and E-cores found on the compute tile. The specifications don't count the LP E-cores in the total core count.
Lastly, the leaked slides claim the Meteor Lake mobile chips will be coming out in the second half of next year, so we're still a long way off from Intel confirming any of these details.
KitGuru says: Intel looks to be placing an increased focus on efficiency improvements with Meteor Lake. Still, we're a long way from an official launch.
