Intel Core Ultra “Panther Lake” Processor Hands-on and Up Close at Computex 2025

Intel at the 2025 Computex showed off its next-generation Core Ultra Series 3 processor, codenamed “Panther Laken.” The mobile H-segment version of the chip comes win a slender rectangular package similar to “Arrow Lake-H” and “Meteor Lake.” It is a tile-based disaggregated processor, but comes in a unique arrangement of tiles we haven’t seen with the past two generations. The chip is dominated by two large tiles, one is very likely the Graphics + SoC tile, the smaller of the two being the Compute tile with the CPU cores, and the slender rectangular tiles being related to I/O.

As for IP, “Panther Lake” introduces a new generation iGPU powered by the Xe3 “Celestial” graphics architecture. The CPU complex consists of “Cougar Cove” P-cores, and “Darkmont” E-cores, both of which are expected to provide generational IPC improvements over the current “Lion Cove” and “Skymont.” At Computex, we not only got to go hands-on with the mobile packages of “Panther Lake,” but also see the chip in action, installed on a testing and platform validation system. The engineering goal with “Panther Lake,” Intel says, is to offer efficiency similar to “Lunar Lake,” but with performance generationally exceeding “Arrow Lake-H.” The Compute tile is expected to be built on the new Intel 18A foundry node. Intel says “Panther Lake” is on track for mass-production in the second half of 2025, with the first consumer products expected at CES 2026.
