Important information has been leaked about Intel’s highly anticipated new processor family, Panther Lake. Data obtained from the company’s own portal, GFX CI, reveals the technical specifications of a model in the series. The leaked processor features a 12-core architecture, a base clock speed of 3.0 GHz, and no Hyperthreading support.
Panther Lake processor performance revealed
According to the leaked information, the Panther Lake processor will have a core layout of 4 Performance (Cougar Cove), 4 Efficiency (Darkmont), and 4 Low Power (LPE). This architecture is specifically aimed at improving energy efficiency in laptops.

Rumors suggest that the Panther Lake family is divided into two distinct segments. The PTL-H models will be aimed at budget and mid-range laptops, while the PTL-U series will appeal to users seeking lower power consumption and long battery life. Previous reports suggested that 16-core versions will also be available, suggesting a variety of options will be available.
The leak’s “model 0xCC” and “stepping 0x2” designations suggest it’s an early version of Panther Lake silicon. It’s been confirmed that the processor will be produced using Intel’s 18A manufacturing process. However, efficiency issues are still being reported.
Previous reports indicated that only 10% of the chips produced met quality standards. This raises questions about whether the series will meet its planned release date of the fourth quarter of 2025.
