Intel’s smallest Core Ultra 300 mobile design is not Panther Lake, meet Wildcat Lake

Intel quietly confirmed at CES 2026 that not every Core Ultra 300 mobile processor is based on Panther Lake. The detail appeared on a slide rather than in the main presentation, and it explains why a couple of low core count SKUs do not fit the standard Panther Lake packaging options.

Intel describes three Panther Lake package configurations that cover the bulk of the 14-SKU lineup. These pair a compute tile with a separate GPU tile and a platform controller tile, with options ranging from a 16-core compute tile (4P plus 8E plus 4LPE) to an 8-core compute tile (4P plus 4LPE), and GPU tiles scaling from 12 Xe3 cores down to 4 Xe3 cores.

Alongside that, Intel has a smaller package design tied to Wildcat Lake. In this silicon, the compute tile integrates the GPU, and the platform controller tile drops to six PCIe 4.0 lanes. Intel lists a 6-core CPU layout (2P plus 4LPE), NPU 5, and an Xe3 iGPU with two Xe3 cores, plus two Thunderbolt 4 ports, Wi-Fi 7, and Bluetooth.

Intel also showed a physical Wildcat Lake package at CES. Photos from the show floor look nothing like Intel’s render , with a visibly different die layout and proportions on the substrate compared to the marketing image.

Intel later told Hardwareluxx that Wildcat Lake is planned for Intel Core Series 3, not for Core Ultra 5 332 and Core Ultra 5 322. Intel says those two Core Ultra 300 models use the smallest Panther Lake package instead. Intel lists availability for Core Series 3 edge and embedded systems in Q2 2026.
