Intel’s next-generation Panther Lake processor has leaked in dramatic fashion! An engineering sample (ES) featuring 10 cores and 16GB LPDDR5X memory was photographed and tested, revealing key specifications ahead of the official CES 2026 unveiling. This early silicon provides our first real-world glimpse at Intel’s 18A node technology.

Intel Panther Lake CPU Leaked and Tested
Leaker YuuKi_AnS shared photos of the engineering sample running on Intel’s Reference Validation Platform (RVP), the same testing rig used during Intel Tech Tour 2025. The chip features a unique 2P + 4E + 4LP-E core configuration with the PTL 16C/4Xe3 tile setup, which doesn’t match any previously leaked SKUs, confirming this is purely an internal testing unit.

Intel Panther Lake Engineering Sample Specs
| Specification | Details |
|---|---|
| Core Configuration | 2 P-Cores, 4 E-Cores, 4 LP-E Cores (10 total) |
| Base/Boost Clock | 3.0 GHz / 3.2 GHz |
| P-Core Clock | 3.0 GHz all-core |
| E-Core Clock | 2.6 GHz across 4 cores |
| Cache | 11 MB L2, 12 MB L3 |
| Memory | 16GB LPDDR5X-7467 (4x 4GB SK hynix modules) |
| Power Limits | 25W PL1, 65W PL2, 160W PL4 |
| TjMax | 100°C |
| Socket | BGA2540 |
| GPU | 4 Xe3 cores |
What the Numbers Mean
The 25W PL1 rating identifies this as a “Panther Lake-U” SKU designed for thin-and-light ultrabooks, while the 65W PL2 allows for short performance bursts. The massive 160W PL4 limit suggests Intel is leaving headroom for extreme thermal scenarios.
Performance expectations should remain tempered—CPU-Z benchmark results weren’t impressive, but that’s typical for A0 stepping engineering samples. Final retail silicon will feature higher clocks, refined power curves, and optimized firmware.

Intel plans to reveal complete Panther Lake details at CES 2026, where we’ll learn about retail SKU configurations, pricing, and availability. The platform promises support for up to 96GB LPDDR5X or 128GB DDR5 memory across its product stack.

FAQs
When will Intel officially announce Panther Lake processors?
Intel will provide full Panther Lake details at CES 2026 in January.
What does the 10-core configuration mean for retail products?
This 2P+4E+4LP-E layout is an internal testing sample and doesn’t match leaked retail SKUs.
