Last month, Intel revealed its "Panther Lake" mobile processor series, featuring up to 16 CPU cores divided into four P-Cores, eight E-Cores, and a four-core LPE cluster. Thanks to reliable Intel leaker @jaykihn0, clock speed details for these CPUs have emerged.

Top-Tier Processor Details

The flagship Core Ultra X9 388H is expected to reach a turbo boost of 5.1 GHz. This is notable given the 16 CPU cores and 12 Xe3 GPU cores on these SoCs, although the GPU frequency remains undisclosed.

TDP and Configurations

The highest-end SKUs can be configured with TDPs up to 65 W or 80 W depending on OEM preferences. Stock PTH-H and PTL-U models are designed to fit within a 25 W TDP.

SKU List for 4+8+4 Core Configuration
