Intel Panther Lake ES CPU photographed with 16 GB LPDDR5X: Engineering sample shows 10-core design and 25 W PL1, 65 W PL2
CES 2026Leaker Yuuki_AnS posted the photos of a Panther Lake ES processor on X. The sample has 10 cores activated and uses the PTL 16C/4Xe3 tile configuration. The CPU uses a 2P + 4E + 4 LP-E layout, which is not part of previously leaked SKUs, implying the photos are from an engineering sample intended for internal testing.
The package is labelled “000C06C0” and uses Intel’s BGA2540 socket.
According to Yuuki_AnS, the ES silicon’s clock speed is 3.0 GHz all-core for the P-cores, 2.6 GHz across all four E-cores, and up to 3.2 GHz boost. The Panther Lake processor has 11 MB of L2 cache and 12 MB of L3 cache.
Tested using Intel’s RVP platform with LPDDR5X memory
The semiconductor was benchmarked with Intel’s Reference Validation Platform (RVP). The setup includes 16 GB of LPDDR5X memory assembled with an ADL-P frame and four SK hynix H58G56BK8BX068-418A modules rated at 7467 MHz.
Early performance appears limited
The ES processor was also evaluated in CPU-Z’s single-threaded and multi-threaded benchmarks. Power readings show a 25 W PL1 target, 65 W PL2, and a high 160 W PL4 limit, with the chip capped at a 100°C TjMax.
Intel intends to provide full details on Panther Lake at CES 2026.
