Intel Lunar Lake appears without hyperthreading as A1 sample leaks confirming key specifications

Intel’s Lunar Lake MX CPUs are said to debut in Q4 2024. While we know a lot already about Lunar Lake, such as efficiency improvements over Meteor Lake and a Battlemage-based Xe2-LPG iGPU, we now have even more information to digest as a Lunar Lake engineering sample running Windows 11 has appeared revealing a ton of details.

Per a screenshot of Windows Task Manager posted on Zihu (via HXL), an A1 LNL sample was running at the base and boost clocks of 1.8 GHz and 2.78 GHz respectively. Additionally, the chip seemingly had 8 cores and 8 threads which aligns with a big leak that dropped in November. The mention of only 8 threads is quite important since multiple rumors have alleged that Intel is ditching Hyperthreading.

Moving on, we can also see from the screenshot that the LNL chip has 832 KB of L1, 14 MB of L2, and 12 MB of L3 cache. Explaining the cache situation of Lunar Lake, Bionic_Squash on X explained that, in addition to 48 KB of L0 and an 8 MB SLC, LNL contains:

• 256 KB and 96 KB of L1 cache for every P and E core, respectively.
• 2.5 MB of L2 per P-core and 4 MB of L2 for the E-core cluster.
• No L3 cache for the E cores while the P cores get 3 MB each.

Long story short, Intel’s Lunar Lake CPUs appear to be under active testing judging from the A1 sample on display indicating that the development is coming along and we could see the launch happen this year. However, we can’t say anything regarding specifications like clock frequencies since the LNL CPU under discussion is clearly an early-stage sample. So, take the information present here as non-final.
