Intel Lunar Lake CPU Leaks Out: 8 Cores, No Hyper-Threading & 27MB of Cache

Lunar Lake is expected to land alongside Arrow Lake in the second half of 2024

Intel’s upcoming Lunar Lake CPUs have been spotted in the wild. We’re looking at an early sample (A1 stepping) with 8 cores and 8 threads, implying that hyper-threading (like Arrow Lake) is absent. The processor features 12MB of L3, 14MB of L2, and 832KB of L1 cache. The L3 is shared among the P and E cores, while the L2 blocks are exclusive to individual P-cores or a quad-cluster of E-cores. Ergo, this is a 4P+4E configuration consisting of 4 Lion Cove and 4 Skymont cores.

The P-cores are expected to feature 2.5MB of L2 cache per core, leaving the remaining 4MB for the E-core cluster. The CPU has a base clock of 1.80GHz and an operating frequency of 2.78GHz, which is modest for an engineering sample. It is paired with 32GB of LPDDR5/5x memory and features an integrated NPU like Meteor Lake.

Here’s all we know about the Lunar Lake processors

  • Lunar Lake is expected to land alongside Arrow Lake in the second half of 2024.
  • It’ll feature the same core architectures (Lion Cove and Skymont) as Arrow Lake.
  • Unlike Arrow Lake, it’ll be fabbed on TSMC’s N3P process node.
  • Its NPU unit will be 2 to 3 times faster than the one on Meteor Lake.
  • The iGPU tile is also expected to offer a healthy 20-40% uplift over the Xe-LPG unit powering Core Ultra.
  • According to Xino, the Lion Cove core will feature an additional L0 cache layer derived from a (renamed) L1 cache. The L1 cache will be a latency-reduced L2 cache layer with a similar width as traditional L2 buffers. It will be a data cache (output).
