As the successor to Lunar Lake, details about the Core Ultra 300 series Panther Lake laptop processors have recently emerged.

According to leaked information, the Panther Lake series processors will utilize Intel's cutting-edge 18A process, featuring Cougar Cove P-Cores, Skymont E-Cores, and Xe3 core graphics.

This hybrid core design enhances performance and efficiency for mobile devices, with some models combining P-Cores, E-Cores, and LP E-Cores in a five-layer package, totaling up to 18 CPU cores.

The revealed SKUs include:

• PTL-H 4+8+4+4Xe 25W
• PTL-H 4+8+4+12Xe 25W
• PTL-H 4+0+4+4Xe 25W
• PTL-H 6+8+4+4Xe 45W
• PTL-H 6+8+4+12Xe 28W

Notably, some models will feature powerful integrated graphics, with up to 12 Xe3 GPU cores, even in the relatively low-power 25W and 28W configurations.

These processors are expected to be officially unveiled in the second half of 2025, with more details likely to follow.
