Panther Lake is the codename for Core Ultra Series 3 mobile processors developed by Intel.^[1] The architecture was launched in January 2026 at CES 2026.^[2]^[3] It succeeds and extends Lunar Lake and is designed as a scalable mobile platform spanning a wider range of power and performance targets, from thin-and-light laptops to higher-performance mobile systems.

Architecture

Panther Lake combines hybrid CPU cores manufactured on Intel's 18A process with integrated graphics based on the Arc Xe³ architecture,^[4] which is derived from the earlier Xe², codename Battlemage, design, along with updated AI acceleration hardware. Rather than introducing a fundamentally new CPU or GPU architecture, Panther Lake focuses on higher core counts, expanded graphics configurations, and increased power budgets enabled by a newer manufacturing node and modular tile-based design, with some models continuing to rely on TSMC manufacturing for the GPU. Instead of developing a more capable NPU, Intel has opted for an optimized, smaller and more efficient NPU that delivers about the same performance as the previous generation's NPU.
