They're both using Lion Cove P-cores and Skymont E-cores which is what I believe the article is getting at. Overall design and implementation for the CPUs themselves is certainly dramatically different.
Maybe but the article's wording can be a bit misleading. But P and E cores aside, the real architecture is "dramatically" different like you mentioned.
Most importantly, actually there has been some architectural changes as well, since we last learned about the low-power LUNAR LAKE lineup. I have mentioned this before as well here at the forums that this new CPU lineup would be replacing E-cores with the SoC-centric
LPE cores instead.
- 4P+0E+4LPE Core Configuration
But some older INTEL slides still mention 4P+4E config, but that has been changed now, as confirmed by multiple sources.
Lunar Lake is actually a spiritual successor to Lakefield, and would feature the Foveros 3D packaging to stack the DRAM dies on top of the SoC.
Lunar Lake CPUs might also drop the "MX" branding and utilize "V" branding instead, LNL-V. This was sort of confirmed via a recent leak, as well as by a leaker on Chinese forum. But this is not yet finalized.

So based on the above info, it would appear that a single die which will feature 4 P-cores based on the Lion Cove core architecture, and 4 LP-E cores based on the Skymont core architecture.
Assuming there aren't any standard E-Cores for Lunar Lake CPUs, this might imply how Intel would be achieving bigger generational "Performance Per Watt" gains with these thin and light series of laptop chips.
Speaking of Battlemage Xe2-LPG iGPUs, we can expect 8 Xe-cores, so that's up to 64 EUs. Few enablement patches have already begun within Linux, and some references such as "64" and "GT1" were already found in the above leak/tweet, especially in the log file.
So let me break this down for Lunar Lake. Rumored/expected specs:
- 4P+0E+4LPE Core Configurations
- They are designed for thin & light Notebooks, low-power devices.
- Support for Lion Cove P-Cores & Skymont LPE-Cores
- Battlemage "Xe2-LPG" GPU Architecture
- Up to 8 Xe2 GPU Cores
- Max up to 64 Execution Units/EUs
- On-Package 32 GB LPDDR5x Memory, rated at speeds of up to 8533 MT/s
- Up To 3x Faster NPU Performance Versus Meteor Lake
- 17-30W TDP
- Launch volume by early/mid 2025. Some models might come out in q4 2024 as well, but in very limited quantities as per insider industry sources.
