Intel’s upcoming consumer platform, Panther Lake, has been spotted in Coreboot files, revealing exciting details about its configurations and capabilities. Coreboot, an open-source firmware, often provides early insights into future hardware, and Panther Lake is no exception.
Panther Lake Configurations
Panther Lake is designed for laptops and is expected to launch no earlier than next year. It remains uncertain whether it will follow Arrow Lake or Arrow Lake Refresh, but it will feature more products than the soon-to-be-released Lunar Lake.
Known Configurations
According to Jaykihn, Panther Lake will come in three primary configurations, featuring 8 or 16 CPU cores and 4 or 12 Xe3 GPU cores. The SKUs are divided into U, P, and H series:
- U Series: Low-power variants (15W)
- P Series: Designed for lightweight laptops
- H Series: Aimed at gaming laptops with the highest TDP (usually 45W)
Detailed Configurations
The Coreboot data indicates four configurations, including a new 45W variant without integrated graphics, suggesting it may be paired with discrete graphics. Here are the configurations:
- Panther Lake-U (PTL-U): 4P + 0E + 4LP + 4Xe3, 15-54W
- Panther Lake-P (PTL-P): 4P + 8E + 4LP + 12Xe3, 25-64W
- Panther Lake-H (PTL-H): 4P + 8E + 4LP + 4Xe3, 25-80W
- Panther Lake-H (PTL-H): 4P + 8E + 4LP + 0Xe3, 45-?W
Power Limits
The Processor Base Power (PBP, also known as PL1) ranges from 15 to 25 watts, with Maximum Turbo Power (PL2) reaching up to 54 or 80 watts. Additionally, PL4 (burst peak power) can go as high as 240 watts, surpassing the limits of Alder, Raptor, and Meteor Lakes.
Comparison with Previous Generations
Compared to previous generations, Panther Lake offers slightly more generous peak power limits (PL4):
| Series | TDP PL1 (W) | TDP PL2 (W) | TDP PL4 (W) |
|---|---|---|---|
| Alder Lake | 15-45 | 55-115 | 123-215 |
| Raptor Lake | 15-45 | 55-115 | 114-210 |
| Meteor Lake | 15-28 | 57-64 | 114-120 |
| Panther Lake | 15-45 | 54-80 | 142-240 |
Production and Future Prospects
Intel announced last month that Panther Lake had successfully booted the operating system, using the Intel 18A node. Production is expected to begin in 2025, alongside the Clearwater Forest platform.
Panther Lake’s configurations and power limits suggest a versatile and powerful platform, poised to cater to a wide range of laptop segments, from ultra-portable devices to high-performance gaming laptops. The inclusion of up to 16 CPU cores and 12 Xe3 GPU cores indicates a significant leap in performance, making Panther Lake a highly anticipated release in the tech community.
