Intel Core Ultra 300 Panther Lake CPUs
New leaks have surfaced about Intel’s upcoming Core Ultra 300 Panther Lake processors, revealing clock speeds reaching up to 5.1 GHz. The company introduced the Panther Lake series last month but did not share SKU-level details at that time.
Leaked Specifications
Information from the leaker Jaykihn shows that the Panther Lake lineup will feature models with core counts ranging from six to sixteen. All CPUs are expected to ship with a base TDP of 25W, though higher-end SKUs may allow significantly higher power limits.

Design and Architecture
Panther Lake will use a chiplet-based architecture, enabling flexible combinations of CPU and GPU cores. Intel’s design includes configurations such as:
- 8-core CPU with a 4-core Xe3 GPU
- 16-core CPU with either a 4-core or 12-core Xe3 GPU
Every model will integrate Intel’s 50 TOPS NPU, highlighting the company's focus on AI-oriented computing efficiency.
Performance Overview
Although the maximum 5.1 GHz boost clock is lower than that of Intel’s desktop CPUs, it aligns with the efficiency goals typical for mobile processors. The combination of high performance and strong AI acceleration positions Panther Lake as a forward-looking platform for laptops and ultrabooks.
