Intel "Panther Lake" Frequencies Leak, 16-Core SKU Hits 5.1 GHz
Early last month, Intel introduced its "Panther Lake" series of mobile processors, featuring up to 16 CPU cores distributed as four P-Cores, eight E-Cores, and an additional four-core LPE cluster. Thanks to reliable Intel leaker @jaykihn0, details on the clock speeds of these mobile CPUs have emerged.
The top-tier Core Ultra X9 388H processor is expected to reach a CPU turbo boost of up to 5.1 GHz. This is notable considering these SoCs include 16 CPU cores alongside 12 Xe3 GPU cores, though the GPU frequency remains undisclosed.
Higher-end SKUs may be configured with a TDP of up to 80 W or 65 W, depending on OEM preference. At stock settings, the PTH-H and PTL-U variants are anticipated to operate within a 25 W TDP.
Core Ultra "Panther Lake" SKU Configurations
- Core Ultra X9 388H: 4 P-Cores, 8 E-Cores, 4 LPE-Cores, up to 5.1 GHz
- Core Ultra 386H: 4 P-Cores, 8 E-Cores, 4 LPE-Cores, up to 4.9 GHz
- Core Ultra X7 368H: 4 P-Cores, 8 E-Cores, 4 LPE-Cores, up to 5.0 GHz
- Core Ultra 366H: 4 P-Cores, 8 E-Cores, 4 LPE-Cores, up to 4.0 GHz
“The top SKUs can be pushed up to 65 W or up to 80 W TDP, depending on OEM's choice; stock models fit within 25 W TDP.”
Class labels such as X9, X7, X5, and regular Core Ultra 9, 7, 5 reflect the known SKU naming conventions.
Overall, Intel's "Panther Lake" platform balances high core counts with efficient power envelopes, positioning it strongly in the mobile processor market.
