Overview

• Panther Lake targets notebooks and mini‑PCs only, with no desktop variant, and is expected as the Core Ultra 300 generation in 2026.
• The mobile lineup adopts a new chiplet partition that merges SoC and CPU functions and comes in two tiers: 4 P-cores with 4 LP‑E cores or 4 P‑cores with 8 E‑cores plus 4 LP‑E cores.
• Intel says both Panther Lake and Clearwater Forest CPU chiplets are built on the 18A process, while it declined to provide clock frequencies or verified performance figures.
• Clearwater Forest debuts as Xeon 6+ for a broader customer base with up to 288 E‑cores using the Darkmont architecture, which Intel claims delivers up to 17% higher IPC versus Crestmont.
• The server package integrates 29 chiplets: twelve 18A CPU tiles linked to three base tiles carrying 576 MB of last‑level cache and 12 DDR5 controllers, two I/O tiles for PCIe 5.0, CXL 2.0 and UPI 2.0, EMIB interconnects, and a 300–500 W package envelope.
