Intel leak hints Panther Lake underwhelms
Unverified benchmark results suggest Intel’s upcoming Panther Lake processors may deliver multi-threaded performance close to that of current Arrow Lake-H chips. The Core Ultra X7 358H scored about 20,000 points in Cinebench R23 Multi-Thread at 65 watts, slightly below the 21,826 points from the Arrow Lake-based Core Ultra 7 255H. The Core Ultra 5 338H reached 16,000 points at 60 watts, compared with 17,988 for the Core Ultra 5 225H at 65 watts.
Both Panther Lake models are early samples. The X7 358H features four performance cores and 12 efficiency cores, with a top boost clock of 4.8 gigahertz. In contrast, the Ultra 5 338H has four performance cores and eight efficiency cores, capable of boosting up to 4.7 gigahertz. Intel has indicated final Panther Lake chips could use 30 percent less power than Arrow Lake-H parts while matching their multi-threaded performance.
Updated graphics benchmarks also show the Panther Lake 12-core Xe3 integrated GPU scoring 6,830 points in 3DMark Time Spy, an 8.5 percent gain over earlier results and roughly 55 percent faster than Lunar Lake’s 8-core Xe2 GPU.
