A potential shift in power strategy for Intel’s next-generation mobile processors has emerged, with leaked power consumption figures for the Panther Lake-H series pointing towards a return to a default 25W PL1 (Processor Base Power). This information, revealed by Twitter user @Jaykihn and reported by IT Home, offers a glimpse into Intel’s plans for its upcoming Core Ultra 300 series mobile processors, built on a new architecture and expected to launch in late 2025.
The Leaked Power Consumption Details:
The leak details power consumption figures (in Watts) for different configurations of the Panther Lake-H processor under Performance Mode and Base Mode, covering PL1 (Processor Base Power), PL2 (Maximum Turbo Power), PL3, and PL4. The data highlights three primary configurations:
- 4P + 8E + 4LPE Cores with 12 Xe3 Graphics Cores: This configuration, aimed at mainstream laptops with integrated graphics, shows a PL1 of 25W in both Performance and Base modes.
- 4P + 8E + 4LPE Cores with 4 Xe3 Graphics Cores: This variant, designed for thin and light laptops with dedicated graphics, also features a 25W PL1. This version is notable for having only one-third the graphics core count of the mainstream version but gaining 8 PCIe 5.0 lanes.
- 4P + 4LPE Cores with 4 Xe3 Graphics Cores: Targeted at entry-level laptops with integrated graphics, this configuration has a 15W PL1 in Base Mode and 25W in Performance Mode.
The 随动 (dynamic) entries, likely referring to dynamically adjusted power limits, show higher PL1 values (45W) and PL2 values (around 95W) for the 4P+8E core configurations, suggesting more aggressive boost behavior when thermal conditions allow.
| Configuration | Mode | PL1 (W) | PL2 (W) | PL3 (W) | PL4 (W) |
| ——————— | ———– | ——- | ——- | ——- | ——- |
| 4P+8E+4LPE, 4 Xe3 | Performance | 25 | 64 | 66 | 175 |
| 4P+8E+4LPE, 12 Xe3 | Performance | 25 | 64 | 66 | 175 |
| 4P+0+4LPE, 4 Xe3 | Performance | 25 | 55 | 57 | 163 |
| 4P+8E+4LPE, 4 Xe3 | Performance (Max) | 65 | 80 | 82 | 239 |
| 4P+8E+4LPE, 12 Xe3 | Performance (Max) | 65 | 80 | 82 | 239 |
| 4P+8E+4LPE, 4 Xe3 | Base | 25 | 64 | 66 | 153 |
| 4P+8E+4LPE, 12 Xe3 | Base | 25 | 55 | 57 | 153 |
| 4P+0+4LPE, 4 Xe3 | Base | 15 | 44 | 46 | 124 |
| 4P+8E+4LPE, 4 Xe3 | Dynamic | 45 | 95 | 97 | 239 |
| 4P+8E+4LPE, 12 Xe3 | Dynamic | 45 | 95 | 87 | 239 |
Implications and Context:
The return to a 25W PL1 for the Panther Lake-H series is noteworthy because it potentially signifies a shift from the higher base power seen in some recent Intel mobile processors. A lower PL1 can contribute to improved battery life and cooler operation under sustained workloads. The different configurations suggest Intel is tailoring its Panther Lake-H offerings to various laptop segments, optimizing for graphics performance, power efficiency, or a balance of both.
The mention of Xe3 graphics cores refers to Intel’s next-generation integrated graphics architecture, promising improved performance compared to current-generation Xe graphics. The thin-and-light variant, with its reduced graphics core count but increased PCIe lanes, suggests a focus on pairing the processor with a discrete GPU for enhanced gaming and content creation capabilities.
Looking Ahead:
Intel’s Panther Lake processors are expected to be manufactured using the Intel 18A process, marking a significant step forward in the company’s manufacturing technology. Intel has confirmed that the first 18A chips have already been produced, and the Panther Lake series is slated for release in late 2025.
The leaked power consumption figures provide valuable insights into Intel’s design choices for the Panther Lake-H series. As the launch date approaches, more details about the architecture, performance, and pricing of these processors are expected to emerge, offering a clearer picture of Intel’s strategy in the competitive mobile CPU market.
