Rumored Intel Core Ultra X7 & X5 “Panther Lake” Chips Boast Multi-Thread Power Rivaling Arrow Lake-H CPUs

Intel’s newest CPUs, the Panther Lake Core Ultra X7 358H and Ultra X5 338H, have reportedly surfaced in Cinebench R23 MT performance leaks, suggesting competitive results against Arrow Lake. These CPUs could potentially match or surpass the performance of their predecessors in multi-threaded tests.

The Rise of Intel Panther Lake

Recently, new benchmarks for Intel’s anticipated Core Ultra X7 358H and Core Ultra X5 338H CPUs have been shared by LaptopReview, comparing them to existing Arrow Lake-H CPUs. The Panther Lake processors, believed to be engineering samples, feature different configurations: the X7 358H with 4 P-Cores and 12 E-Cores and the X5 338H with 4 P-Cores and 8 E-Cores, both with preliminary boost clocks.

The performance comparisons highlight that the Ultra X7 358H scores approximately 20,000 points in Cinebench R23 MT, close to the Arrow Lake Ultra 7 255H at around 21,826 points. Similarly, the Ultra X5 338H achieves 16,000 points, compared to the Ultra 5 225H’s 17,988 points. These figures indicate that Panther Lake CPUs might deliver similar performance levels to Arrow Lake-H models.

Enhanced Graphics and Upcoming Launches

Beyond CPU benchmarks, the Panther Lake 12Xe iGPU shows promising results with an 8.5% performance increase in 3DMark Time Spy, scoring up to 6830 points. This improvement suggests the Xe3 iGPU could be up to 55% faster than the Lunar Lake’s 8Xe2 iGPU.

Intel’s Panther Lake CPUs continue to generate excitement as they are expected to offer significant power savings, with reported 30% savings at equal performance levels to Arrow Lake-H in multi-threading tasks. The first Panther Lake SKUs are anticipated to debut this quarter, with a full launch planned for CES 2026 in January.
