Igor’s Lab has published an overview diagram of Intel’s 14th Core generation Meteor Lake mobile CPU architecture. This shows a third type of core, LPE cores, which could be low-power cores. There is also talk of a new Xe-LPG graphics architecture based on Xe².
New information on Intel’s Meteor Lake mobile CPU lineup, succeeding Raptor Lake, has been compiled into a platform chart by Igor’s Lab. Accordingly, there are mobile Meteor Lake processors in the categories U, P and H, which are each intended for different performance segments.
Meteor Lake with LPE cores and new graphics architecture
Interestingly, there is a change to the core architecture, because in addition to the usual P and E cores, LPE cores are also called. This could be the abbreviation for Low Power Efficient Core, as there had been rumors about small cores with low power consumption beforehand. The Twitter user “Raichu” meanwhile claims that the LPE cores are housed in the SoC die and not in the compute die, where P and E cores are implemented. There are also said to be only two ULP cores (Ultra Low Power), which would explain , why they are not included in the total number of CPU cores.
In terms of total core count, Meteor Lake-H and Meteor Lake-P each have 14 cores (6 P +8 E cores), and Meteor Lake-U has 12 cores. The RAM architecture should support DDR5-5600 or LPDDR5/LPDDR5X-7467. At DDR5 level it goes up to 96 GiByte and at LPDDR5 up to 64 GiByte. The platform overview also shows a new Xe-LPG graphics architecture from Intel based on the Xe². This is integrated in all three product lines and should have up to 128 execution units. It is not clear which GPU architecture Xe² includes here. It could be next-gen Battlemage or a new low-power version of Alchemist.

In addition, Meteor Lake should provide up to eight lanes for the PCI Express 5.0 interface for dedicated graphics, but exclusively for mobile H-CPUs. Support for M.2 PCI-E 5.0 is not mentioned. Finally, the platform overview from Igor’s Lab reveals a release period for the mobile Meteor Lake CPUs. Those should be planned for the second half of 2023.
