Intel's upcoming Panther Lake laptop CPU configurations previously leaked , revealing a line-up ranging from the modest Core Ultra 3 320U, with 2 P-Cores and 4 LPE-Cores to the notably higher-end Core Ultra X9 388H, featuring 4 P-Cores, 8 E-Cores, and 4 LPE-Cores. Now, performance figures for the more mid-range Intel Core Ultra X7 358H and Core Ultra 5 338H have both been leaked, thanks to Laptopreview Club . According to the site, the Core Ultra X7 in question managed a Cinebench R23 score of around 20,000, while the Core Ultra 5 338H came in at around 16,000 points or 20% slower than the X7 variant—the site doesn't provide exact scores, only rounded figures, but it's some idea of what to expect in terms of CPU performance for the next-gen Intel CPU platform.

As previously discussed, Panther Lake appears to be focusing more on iGPU performance, with leaked benchmarks revealing RTX 3050-tier performance from the 12-core Xe3 iGPU solution, but this is the first indication of CPU performance for the new CPU generation. The leaker claims that the 358H will be around 10% slower than the 255H at the same power consumption, in this case 60-65 W, with Cinebench R23 scores for the 255H ranging from the low 17,000s to upwards of 22,000. It appears, thus, that Panther Lake may sacrifice some CPU performance in order to improve iGPU performance, although these are still early rumors, and things are subject to change ahead of launch. The idea that Intel would launch a new CPU that underperforms its old platform by such a margin seems unlikely. It's possible that these tests were on the lower side of average or a worst-case scenario, either of which would actually make the performance of the new CPUs reasonably impressive.
