Intel Panther Lake mobile processors to debut in 2026
Intel’s upcoming Panther Lake mobile processors have appeared in fresh specifications detailing performance targets and chip configurations for the Core Ultra 300 lineup. The flagship Core Ultra X9 388H combines four performance cores with eight efficiency cores and four low-power efficiency cores, reaching maximum speeds of 5.1 gigahertz at 45 watts thermal output. Graphics processing relies on 12 execution units using Battlemage-based Xe3 architecture.
Additional models span thermal envelopes from 18 watts through 28 watts for compact notebooks. The Core Ultra 386H and X7 368H achieve peak frequencies between 4.9 and 5.0 gigahertz while budget variants settle around 4.5 gigahertz. Core counts range from 16 cores down to six, depending on the target market segment and power requirements.
The processor family employs four distinct arrangements pairing performance and efficiency elements through Foveros packaging methods. High-output versions carry 16 total cores while entry-level chips use six cores optimized for ultra-thin form factors. Launch timing points toward 2026, with initial availability expected in premium ultraportable computers and gaming laptops competing against AMD Strix Point designs.
