Panther Lake CPUs leak with 4.6GHz boost and 12MB cache

Two new Intel Panther Lake processors just popped up on Geekbench, the Core Ultra 5 335 and 325. These are the regular non-H series chips aimed at thinner laptops, sitting in a higher power range than the current Lunar Lake parts. Both are eight-core chips using a mix of four performance cores and four low-power efficiency cores, lacking the standard E-cores entirely. They look like the direct follow-ups to the Ultra 200V lineup.

The benchmark listings, spotted in a Dynabook laptop, show similar performance between the two models. The Ultra 5 335 hit around 1991 in single-core and 9527 in multi-core tests on Geekbench 5.5.1, while the 325 scored roughly 1923 and 9397. These numbers are basically meaningless for comparison, though, because everyone tests newer chips on Geekbench 6. We need those scores to see how they stack up against older processors.

Specs from the leak confirm a boost clock up to 4.6 GHz for the 335 and 4.5 GHz for the 325, along with 12 MB of L3 cache. That's a decent cache bump over the previous generation. A full preliminary lineup chart shows these chips alongside more powerful H-series models, all featuring Intel's next-gen core architectures and Xe3 graphics. We're still waiting on meaningful benchmarks from the newer Geekbench version to actually judge performance.
