Intel 16th Gen Panther Lake (Core Ultra 300) CPUIDs Added to Linux Coreboot

Let’s dive into the details of Intel’s upcoming 16th Gen Panther Lake processors, also known as the Core Ultra 300 series. These CPUs are expected to be a significant leap forward in terms of performance and architecture.

Here’s what we know so far:

  1. Panther Lake Overview:

    • The 16th Gen Core processors, codenamed Panther Lake or Core Ultra 300, will be the first client lineup to feature Intel’s 18A process.
    • According to the official client roadmap, Panther Lake is set to launch in the second half of 2025.
    • Unlike previous generations, Panther Lake will likely focus on mobile/laptop designs, emphasizing power efficiency, integrated graphics, and AI performance.

  2. Architecture and Process:

    • Panther Lake will likely feature two core architectures: Cougar Cove P and Skymont E-core.
    • Cougar Cove P is a node shrink (tick) that aims to improve process efficiency and battery life.
    • Skymont E-core, debuting with Arrow Lake, should benefit from the node upgrade.
    • The CPUIDs of early Panther Lake samples have been added to Linux Coreboot, with identifiers “0xC06C0” and “0xC06C1”.

  3. Graphics and NPU:

    • Originally, Panther Lake was supposed to leverage the Celestial (Xe3) graphics architecture. However, considering that Battlemage (Xe2) is yet to make an appearance, this remains uncertain.
    • The Neural Processing Unit (NPU) unit in Panther Lake will be upgraded to at least 60 TOPs (up from <20 TOPs on Meteor Lake) and ~40 TOPs on Lunar Lake.

  4. Advanced Chiplet Architecture:

    • Recent reports suggest that Panther Lake will launch in 2026, leveraging an advanced chiplet architecture.
    • This architecture consists of an 18A compute die and a 3nm (or 2nm) graphics tile fabbed on a TSMC node.

  5. Rentable Unit Cores (RUs):

    • Panther Lake, leveraging the Cougar Cove core, is expected to offer a 40% IPC boost over an earlier designed 4-way hyper-threaded model.
    • RUs are akin to addressable cores, packed in groups of two, each with a chunk of SRAM and sharing MLC per unit.

In summary, Intel’s 16th Gen Panther Lake processors promise exciting advancements in performance, architecture, and efficiency. As we await their official release, tech enthusiasts can look forward to a new era of computing power! 🚀🔥
