Details have emerged about Intel's upcoming "Panther Lake" processors, set to be the third generation of Core Ultra mobile chips. Called the Core Ultra 300 series, these CPUs are expected to succeed "Lunar Lake". According to recent leaks, Panther Lake-H will be manufactured using Intel's cutting-edge 18A process node. The chips are said to feature a combination of Cougar Cove P-Cores, Skymont E-Cores, and Xe3 (Celestial) integrated graphics. This architecture builds upon Intel's hybrid core design, refining it for even better performance on mobile devices. The leaked information suggests a range of configurations for Panther Lake-H, the high-perfomance variant of the lineup. These include models with varying core counts and power envelopes, from efficient 25 W parts to more interesting 45 W options. Notably, some SKUs reportedly feature up to 18 cores in total, combining P-cores, E-cores, and LP E-cores in a five-tile package. This is an increase from previously believed 16 cores.
Here are the leaked SKUs:
PTL-H 4+8+4+4Xe 25 W
PTL-H 4+8+4+12Xe 25 W
PTL-H 4+0+4+4Xe 25 W
PTL-H 6+8+4+4Xe 45 W
PTL-H 6+8+4+12Xe 28 W
One of the most intriguing aspects of the leak is the inclusion of powerful integrated graphics in some models. Certain SKUs are said to boast 12 Xe3 GPU cores, even in relatively low-power 25 W and 28 W configurations. This could significantly boost graphics performance in thin and light laptops. Some high-wattage SKUs, like the 45 W model, should be configured with higher clocks. While these specifications are still subject to change before the official release, they provide an exciting glimpse into Intel's future mobile offerings. The Panther Lake series is expected to debut in the second half of 2025 if everything goes according to plan at Intel HQ.
