Reputable leaker Jaykihn has revealed the full specifications for Intel's upcoming Panther Lake and Wildcat Lake series. Both are expected to launch as part of the Core Ultra 300 series later this year.

Jaykihn's leak corroborates previous indications from Linux patches that Panther Lake is destined exclusively for mobile platforms. Interestingly, only three Panther Lake variants are detailed in this leak, down from the four previously rumoured. Something worth pointing out is the core configuration: up to 16 cores, comprised of 4x P-cores, 8x E-Cores, and 4x LP-cores. The low-power core configuration seems consistent across all Panther Lake variants, including the mainstream series known as Wildcat Lake, which is also detailed in the leak.

For laptop gamers, the most interesting option should be the 4P+8E+4LP+4Xe3 configuration. While this variant features significantly fewer GPU cores (three times less) than the top-tier configuration, it compensates with three times the PCIe 5.0 lanes (12), likely catering to discrete GPUs and M.2 SSDs. The Panther Lake variant with 12 Xe3 GPU cores will reportedly have only four PCIe 5.0 lanes but should offer decent graphics performance even if the system doesn't include a discrete GPU.

Jaykihn also sheds light on a third H-series variant, which reportedly has no E-cores, mirroring Lunar Lake's configuration with half the GPU cores (but using the Xe3 architecture). Wildcat Lake, it seems, will be a 6-core part with 2P+4LP cores, 2 Xe3 GPU cores, and up to 6x PCIe 4.0 lanes.

Lastly, NPU performance figures suggest a total platform AI TOPS of 180 for the 12-core iGPU Panther Lake variant and 100 TOPS for the other two. Wildcat Lake, on the other hand, will offer the minimum 40 TOPS required to meet the Windows Copilot+ PC specifications.

KitGuru says: Contrary to what Intel is expected to bring to the desktop segment in 2025, the upcoming laptop products (namely Panther Lake) look much more promising. Besides the possibly better Cougar Cove CPU P-cores, we're reportedly getting better NPUs and 12-core iGPUs with a new architecture.
