Intel "Panther Lake" Frequencies Leak, 16-Core SKU Hits 5.1 GHz
Early last month, Intel unveiled its "Panther Lake" series of mobile processors, featuring a total of 16 CPU cores divided into four performance cores (P-Cores), eight efficiency cores (E-Cores), and an additional four-core low-power cluster (LPE).
Reliable Intel leaker @jaykihn0 revealed details about their clock speeds. The leading Core Ultra X9 388H processor can reach a turbo boost clock of up to 5.1 GHz, an impressive feat for a 16-core SoC. These chips also include 12 Xe3 GPU cores, though their frequency remains undisclosed.
Top-tier SKUs are configurable with power envelopes of either 65 W or 80 W TDP, depending on OEM choices. The PTH-H and PTL-U models are expected to operate within a 25 W TDP at stock settings.
Confirmed SKUs and Specifications
- 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.X GHz (exact frequency incomplete)
"Thanks to reliable Intel leaker @jaykihn0, we have details on the clock speeds of these mobile CPUs."
"The top-tier Core Ultra X9 388H processor is expected to have a CPU turbo boost of up to 5.1 GHz."
These new Intel mobile processors represent a significant step in balancing core counts and high clock speeds, likely impacting gaming and productivity laptops with powerful performance and configurable power limits.
Summary: Intel's "Panther Lake" mobile processors combine a 16-core CPU design with up to 5.1 GHz turbo boost, delivering strong performance across configurable power envelopes from 25W to 80W.
