12-Core Intel Panther Lake Detected in GFX CI Portal; No Hyperthreading and 3.0 GHz Base Clock

The recent leak regarding the Panther Lake CPU reveals a significant update: it will not support hyperthreading and will be equipped with 12 cores. This likely represents a hybrid architecture that includes Performance, Efficient, and Low Power Efficient cores.

Panther Lake Mobile Chip Specifications Leaked: Featuring 12 Cores and a 3000 MHz Base Clock

Details about Intel’s anticipated Panther Lake mobile processors have begun to emerge, showcasing potential specifications for various models. Panther Lake is categorized into two segments: PTL-H, designed for budget to mid-range mobile devices, and PTL-U, which aims to enhance power efficiency and extend battery performance.

Recent reports, including insights from @InstLatX64, suggest that certain Panther Lake chip configurations may comprise up to 16 cores. This aligns with findings from the Intel GFX CI Portal, known for its role in testing Intel’s open-source drivers for Linux graphics, where Panther Lake is explicitly mentioned.

Panther Lake’s architecture marks the final chapter for the Family 6 series, transitioning to Family 18 with the introduction of Nova Lake processors. The model identifier “0xCC”denotes Panther Lake, while the stepping code “0x2″signifies its silicon revision. The reported configuration of this specific chip is set to include 12 cores, potentially realized through a mix of 4 Performance (Cougar Cove) and 8 Efficient cores (Darkmont).An alternative configuration of 4P+4E+4LPE (Low Power Efficient) is also a possibility, although confirmation is still pending.

Notably, this CPU will not incorporate hyperthreading, and its base clock speed is projected to be 3.0 GHz. According to another leak from @InstLatX64, it may achieve boosts of up to 3.2 GHz. However, it’s essential to approach these specifications with caution, as they may not yet reflect the final product. For example, while the Core Ultra 7 255H was initially reported with a 3.7 GHz base clock, this turned out to be inaccurate, whereas the more recent confirmation for the Core Ultra 5 238V at 2.1 GHz was accurate prior to launch.

Set to be built on Intel’s 18A technology node, the Panther Lake series is anticipated to hit the market in the fourth quarter of this year. However, it faces challenges related to production, particularly concerning yield rates of the 18A node.
