First Intel Panther Lake CPU benchmarks leak

While the graphics performance of Intel's upcoming “Panther Lake” mobile CPUs has been the subject of much speculation, we now have our first look at the platform's CPU capabilities.

Laptopreview (via VideoCardz) has shared a set of Cinebench R23 multi-core benchmarks for two of the new Core Ultra 300 series chips. According to the new data, the top-tier Core Ultra X7 358H scored approximately 20,000 points in the Cinebench R23 multi-core test, about 10% less than the Core Ultra 7 255H. A second chip, the Core Ultra 5 338H, reportedly scored around 16,000 points in the same benchmark. Both of these tests were allegedly conducted at a TDP of 60/65W.

The specs for these chips were also detailed, aligning with previous rumours. The Core Ultra X7 358H is reportedly a 16-core processor, comprising four P-cores, eight E-cores, and four LP-cores, and will feature a 12-core Xe3 integrated GPU. The Core Ultra 5 338H is a step-down 12-core model, which achieves its lower core count by reducing the number of E-cores to four.

While the CPU performance numbers are new, the leak also provided an updated graphics score. The Time Spy score for the Core Ultra X7 358H is now listed at 6,830 points, compared to the initial reports of around 6,200 points. If these latest numbers are accurate, that's over 70% faster than the Core Ultra 7 255H's integrated GPU.

KitGuru says: It's a bit disappointing to see a lower CPU performance in the multi-core test, but the massive uplift in the graphics capabilities of this chip makes up for it.
