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 a Heterogeneous CPU core tile manufactured on Intel’s in-house 18A process with and integrated graphics tile based on the Arc Xe3 architecture,[4] which is derived from the earlier Xe2—codename Battlemage—design, and an I/O tile Manufactured on TSMC N6 Process.

The Clusters obviously vary in size, there’s a Big 4+8+4 Core Tile reserved for the H-Series, and a Small 4+4 Core Tile reserved for the Low powered Processors. Non-Arc H-Series CPUs also are the only processors in this lineup to utilize the larger I/O Tile, while Arc H-Series and Low Powered CPUs use the smaller core tile. Said Tiles both Support DDR5 and LPDDR5X, however, The larger tile has more PCIe Lanes whereas the smaller tile has fewer PCIe Lanes, Arc H-Series CPUs use a binned version of the smaller I/O Tile that doesn’t support DDR5. There are also Smaller GPU Tiles which have up to 4 Xe Cores, and Larger GPU Tiles which have up to 12 Xe tiles, The latter being branded and labeled as Arc B390/B370 If the machine using it reaches memory speeds of atleast LPDDR5X-7467, otherwise they will be relabeled as just “Intel Graphics” in Task Manager[5], some models with the larger GPU tile continue to rely on TSMC manufacturing for the GPU on its N3E process possibly due to budget concerns.[6]

Rather than introducing a fundamentally new CPU or GPU architecture, Panther Lake focuses on higher core counts, better graphics configurations, and increased power budgets enabled by a newer manufacturing node and modular tile-based design

Furthermore, 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.

Reception

Panther Lake has been widely praised for its power-efficiency and integrated graphics performance, having been noted as a “return to form” for Intel.[7][8][9]
