A brand new Intel Lunar Lake CPU sample has leaked out which has revealed more info on the upcoming Core Ultra platform for thin & light notebooks.

Intel Lunar Lake Launches Later This Year & The First CPU Samples Are Already Leaking Out With 8 Cores & 8 Threads

The leak comes from XZiar at Zhihu who has reportedly obtained a screenshot of the task manager on an alleged Intel Lunar Lake CPU-powered notebook. According to the user, this sample is an "A1" stepping and if true, it looks like Intel's Lunar Lake might just be on time for its release later this year.

Diving into the details, the Intel Lunar Lake CPU is an early sample that is listed as "Genuine Intel (R) 0000 1.00 GHz" in the task manager. The chip has a base clock of 1.80 GHz and a boost clock of 2.80 GHz but that's only with a 33% utilization. Intel Lunar Lake CPUs are expected to be fabricated on Intel's 20A process node and will feature a major boost to clock speeds compared with existing Meteor Lake CPUs which saw a clock speed regression when moving from Intel 7 to 4.

Powering the Intel Lunar Lake CPUs will be two major core architectures, the Lion Cove P-Cores and the Skymont E-Cores. The CPU sample comes with 8 cores and 8 threads but while the core config is not known for sure, it might be 4 P-Cores and 4 E-Cores. The exclusion of SMT for the P-Cores is also something that we have previously seen listed for early Arrow Lake samples. As for the cache, the CPU is configured with 832 KB of L1, 14 MB of L2, and 12 MB of L3 cache. This is a very unique cache number and we can use these numbers to compare it with existing Meteor Lake and Raptor Lake CPUs.

As per Bionic_Squash, the Lion Cove P-Cores on the Lunar Lake CPUs incorporate 48 KB of L0D, 192 KB of L1D (alleged), 64 KB of L1i, 2.5 MB of L2, and 3 MB of L3 cache while the Skymont E-Cores will have 64 KB of L1i, 32 KB of L1D, 4 MB of L2 and no L3 cache for the Lunar Lake chips. The L3 cache will be present on the rest of the chips that feature the Skymont E-Cores. The SLC will be 8 MB. The following is a breakdown of the different cache counts:
