Intel Panther Lake-H Details Leak Online
Intel is gearing up for a revolution in portable computing, as preliminary specifications for the Panther Lake-H processors have surfaced online. Expected to be part of the Core Ultra 300 lineup set for late 2025, these chips promise not only record-breaking clock speeds but also flexible configurations, including models without efficiency cores.
Initially, Panther Lake-H was believed to operate within a 25-45W range. However, insider Jaykihn reports that maximum power could reach 64W in Performance mode—a 42% increase over prior estimates and nearly double that of the current Lunar Lake generation (17-30W). This move likely targets competition with ARM chips while enhancing gaming devices like the ASUS ROG Ally.
According to leaked documents, Panther Lake-H will come in three variants:
- 4+8+12Xe: 4 performance cores, 8 efficiency cores, and 12 Xe3 graphics cores—Intel’s top-tier option for gaming and rendering.
- 4+8+4Xe: A balanced model with a scaled-down GPU.
- 4+0+4Xe: A unique configuration with no efficiency cores, possibly designed for workloads requiring stable performance without core switching.
The Xe3 GPU, a successor to Lunar Lake’s Xe2, triples the number of cores in its highest-end variant. This could mark a major leap for integrated graphics, bringing them closer to entry-level discrete GPUs. The documents also outline four power levels (PL1-PL4), with baseline operation (PL1) starting at 15-25W. In extreme scenarios (PL4), power draw can momentarily spike to 239W—figures more typical of desktop CPUs, likely necessitating advanced cooling solutions.
Intel has yet to comment on the leaks, but if the information holds true, Panther Lake could be a game-changer for AI-powered laptops and mobile gaming. Final specs may still change, but one trend is clear: the future belongs to adaptive processors that dynamically adjust to user workloads.
