Intel Lunar Lake iGPU to Pack 64 Battlemage Xe2 Execution Units

Hardware leaker Bionic_Squash has leaked the specifications of Intel’s yet-to-launch Lunar Lake mobile platform. Lunar Lake should arrive for the mobile segment sometime after Arrow Lake. Apparently, these CPUs will make use of the Battlemage ‘Xe2‘ architecture for their iGPU.

It has been claimed that Lunar Lake should ship with 64 EUs based on Xe2. This is significantly smaller than Meteor Lake’s 128 EU offering.

Lunar Lake iGPU to Feature 64 EUs

Lunar Lake is a mobile-only series planned for 2024 or 2025. It should be built on the 18A process node. MLID claims Lunar Lake will feature the Lion Cove+ architecture for the P-cores and resort to Skymont for the E-cores.

Lunar Lake will utilize the Alchemist-next architecture codenamed ‘Battlemage‘ for its iGPU. We should see a maximum of 64 Xe2 Execution Units. This translates to 4 Xe-Cores, however, Battlemage will move to SIMD16 much like Ponte Vecchio, so the Xe-Core count remains at 8. This is because now each Xe-Core will contain 8 Vector Engines (EUs), instead of 16 which we saw with Alchemist Arc.

An Xe-Core is the building block of Arc and contains 8 EUs (16 on Alchemist). EUs or Execution Units are more formally referred to as Vector Engines. As per the same leaker, this configuration should equate to 1024 FP32 Units. In reality, since the architecture is different, we cannot compare performance that easily.

If this leak is true, Battlemage may see the light of day before 2025. There have been rumors about Arc being canceled, as such this rumor serves as a ray of hope.

Release Date

We currently do not have any information about the release date of Lunar Lake. It should launch with Lion Cove+, a modified variant of Lion Cove used on Arrow Lake. The release date should be somewhere in 2025.

Since this platform primarily plans to establish Intel’s lead in low-power and efficient laptops, MLID claims that Lunar Lake CPUs will have a maximum of just 8 cores. We will not comment on the thread count as Intel plans to disable SMT with Arrow Lake.
