Panther Lake (microprocessor)
Intel microprocessor, released in 2026
From Wikipedia, the free encyclopedia
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 an integrated graphics tile based on the Arc Xe3 architecture,[4] which is derived from the earlier Xe2 (Battlemage) design, and an I/O tile manufactured on TSMC's N6 process.
The clusters vary in size: The big 4+8+4 core tile is used in the H series, and the small 4+4 core tile is used in the low-power 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-power CPUs use the smaller core tile. Said tiles both support DDR5 and LPDDR5X memory, 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 at least LPDDR5X-7467, otherwise they will be labeled as just Intel Graphics[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.

List of Panther Lake processors
Panther Lake CPUs omit hyper-threading support, so they can run the same number of threads as they have cores.
