Detailed Power Ratings for Intel Panther Lake CPUs: 25W H-Series and Performance Mode Reaching 64W at PL2

The forthcoming Intel Panther Lake CPU series is set to deliver impressive performance with a frequency range of 25-64W in its performance mode. Recently, more details about these innovative processors have surfaced, shedding light on their configurations and power specifications.

Intel Panther Lake “Core Ultra 300”: Specs Overview

Expected to debut in late 2025, the Intel Panther Lake-H CPUs have been the subject of speculation for some time. Following the initial unveiling of this chip last year, significant information has surfaced regarding the Core Ultra 300 series. A newly leaked preliminary specifications sheet has provided a detailed account of the core configurations and power levels associated with various models.

This leaked document reveals the presence of Panther Lake-H CPUs (PTL-H) categorized into Performance and Baseline specifications. Notably, information attributed to the leaker @jaykihn0 corroborates earlier details shared about the Panther Lake-H series.

Core Configurations of Panther Lake CPUs

The PTL-H processors come in three distinctive configurations:

4+8+4Xe: Featuring 4 Performance Cores, 8 Efficient Cores, and 4 Xe3 integrated graphics cores.
4+8+12Xe: Comprising 4 Performance Cores, 8 Efficient Cores, and 12 Xe3 iGPU Cores, offering superior graphical capabilities.
4+0+4Xe: Consisting of 4 Performance Cores, no Efficient Cores, and 4 Xe3 iGPU Cores.

To clarify, the notation “4+8+4Xe”breaks down as follows: “4”denotes four Performance cores, “8”indicates eight Efficient cores, and “4Xe”represents four cores powered by the Xe3 architecture, which is the next evolution from Xe2, already in use in Lunar Lake processors.

The most potent variation, equipped with 12 Xe3 cores, is expected to handle graphical tasks much more effectively compared to configurations with fewer cores. Interestingly, the Panther Lake-H models are set to feature enhanced Max Turbo Boost capabilities, with power limits previously estimated between 25-45W, now adjusted to a peak of 64W.

Power Configurations of Intel Panther Lake CPUs

Configuration	PL1 W	PL2 W	PL3 W	PL4 W	IA Iccmax
4+8+12Xe	25/25/65	64/64/80	66/66/82	153/175/239	80/80/148
4+8+4Xe	25/25/65	55/64/80	57/66/82	153/163/239	80/80/148
4+0+4Xe	15/25/-	44/55/-	46/57/-	124/163/-	80/80/-

The table above illustrates several power labels—PL1 denotes base frequency, while PL2 highlights the maximum Turbo Boost frequency. PL3 and PL4 provide additional boost options during intensive tasks. The Panther Lake CPUs will notably operate within a 25-64W range in performance mode, while their baseline power consumption will vary by configuration, beginning from either 15W or 25W, up to 44W/55W/64W.

This escalation in the power bracket signifies substantial improvements in both power efficiency and performance, particularly when compared to the Intel Lunar Lake processors, which are restricted to a power range of 17W-30W. It’s important to note that the above specifications are preliminary and may evolve leading up to the official launch. Confirmation from Intel regarding these specifications is still pending, though indications suggest that the focus will be predominantly on mobile platforms, including handheld gaming devices.
