Intel “Lunar Lake” spotted running Windows 11

Intel’s next-generation low-power architecture called Lunar Lake has witnessed a large leak today.

The upcoming Lunar Lake architecture is on track to expand Intel’s plans for ultra-low mobile power systems, succeeding the just-deployed Core Ultra 100U “Meteor Lake-U”. Scheduled to hit the market alongside the more potent Arrow Lake CPUs later this year, both Lunar Lake and Arrow Lake are currently undergoing testing and evaluation, with Intel partners already in possession of the latest silicon.

The latest leak has unveiled the alleged Lunar Lake processor in its A1 stepping. Confirming the presence of 8 cores and 8 threads (without hyper-threading, as also expected from the Arrow Lake series). This leak also spills the beans on CPU core cache sizes. The Lunar Lake die will feature four Lion Cove cores and a cluster of four Skymont cores. Notably, these same types of cores are slated for use in the Arrow Lake series.

Intel Lunar Lake Cache & Clocks:

• L1 Cache : 836KB (112KB per P-Core, 96KB per E-Core)
• L2 Cache: 14MB (2.5MB per P-Core, 4MB per four E-Cores)
• L3 Cache: 12MB
• Base Clock : 1.8 GHz (A1)
• Boost Clock: ~2.8GHz (A1)

According to Tom’s Hardware , it would appear that L2 cache for Lunar Lake (14MB) will actually be larger than L3 cache (12MB). The L2 cache combines 2.5MB per each Performance cores and 4MB combined for a cluster of Efficient Cores. The screenshot posted by XZiar on a Chinese social platform does not show hyper threading either.

Additionally, the leaked information discloses a base clock of 1.8 GHz for the Intel Lunar Lake processor, with a boost clock reaching 2.78 GHz, as seen with 33% CPU utilization when the screenshot was captured. This may not represent the full clock speed, especially considering it is an early A1 silicon.

There was a significant leak surrounding Intel Lunar Lake just a few months ago. It shared crucial details such as power rating options of 8W and 30W or support for LPDDR5X-8533 memory.  The most important detail for GPU enthusiasts is the upgraded graphics subsystem to 8 Xe2-Cores, a low-power derivative of the discrete Battlemage architecture.
