Early last month, Intel introduced its "Panther Lake" series of mobile processors, featuring up to 16 CPU cores distributed across four P-Cores, eight E-Cores, and an additional four-core LPE cluster. 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. This is impressive given that these SoCs include 16 CPU cores and 12 Xe3 GPU cores, whose frequency remains undisclosed. The top SKU is rated for a 45 W TDP category, while the PTH-H and PTL-U configurations are expected to fit within an 18-28 W TDP range.
