Rumor mill: Intel's upcoming Lunar Lake processors could offer a massive multithreaded performance gain over Meteor Lake, according to a new rumor. Chipzilla is expected to launch Lunar Lake later this year as the third lineup under its Core Ultra brand, with the U-series chips meant for ultra-portable laptops and convertibles.

The latest report comes from tipster extraordinaire @SquashBionic, who claims that the 17W Lunar Lake U-series chips will offer a 50 percent improvement in multi-threaded performance over the current-gen 15W Meteor Lake processors. The next-gen chips were earlier rumored to offer higher performance per watt and faster AI NPU performance, and the latest report now suggests that those claims were fairly accurate.

In another tweet, the tipster wrote that the 17W TDP was the original PL1 spec for single-fan configurations, but Intel has decided to extend the cTDP to 30W due to popular demand from OEMs. There's no word on specific SKUs, so we don't know how many of them will still ship with the original 17W TDP and how many will get the enhanced 30W spec for improved performance. However, if the 17W SKUs can offer a 50 percent higher performance than Meteor Lake, it is anybody's guess as to how much faster the 30W chips will be.

According to prior rumors, the Lunar Lake processors will feature Lion Cove Performance Cores, Skymont Efficient Cores, and a fast Neural Processing Engine (NPU) that is said to offer thrice the performance of the NPU found in the Meteor Lake chips. The next-gen processors are also expected to get a brand new iGPU based on the Battlemage Xe2-LPG architecture.

For all its improved specs, Lunar Lake will reportedly ditch hyper-threading support on its P-cores, which could theoretically affect their multi-threaded performance. If the rumors hold up, the 17W Lunar Lake CPUs will ship with up to 4 P-Cores and 4 E-Cores, totaling up to 8 cores and 8 threads, while the 15W Meteor Lake chips cited in the post offer 2 P-cores, 8 E-Cores, and 2 LP-E cores for a total of 12 cores and 14 threads.
