Intel Core Ultra 7 268V “Lunar Lake” Final CPU With 5 GHz Clocks

Intel’s Lunar Lake is a highly advanced and efficient System-on-Chip (SOC) that aims to revolutionize next-gen AI PC platforms. Here are the key highlights:

  1. Design Goals:

    • Lunar Lake was designed with simplicity and efficiency in mind.
    • It caters to next-gen AI PC platforms, including Microsoft Copilot+.
    • The chip aims to achieve breakthroughs in power efficiency, core performance, graphics, and AI compute.

  2. Construction and Packaging:

    • Lunar Lake features several packaging technologies, including an interposer package.
    • The interposer hosts memory, stiffener, and the Base Tile, which combines the compute tile and Platform Controller Tile using Foveros interconnect.
    • Fewer tiles were used compared to Meteor Lake to maximize efficiency and reduce latency overhead.
    • Process nodes: The Compute Tile is made on TSMC’s N3B, while the Platform Controller die uses TSMC N6.
    • On-package memory: Lunar Lake boasts 16 GB & 32 GB LPDDR5X configurations, running at up to 8533 MT/s speeds per chip.

  3. Hybrid Core Design:

    • Lunar Lake employs an 8-core hybrid design with P-Cores and E-Cores.
    • P-Cores (Lion Cove):
      • Improved single-threaded performance.
      • 2.5 MB L2 cache per core.
      • Up to 12 MB shared L3 cache.
    • E-Cores (Skymont):
      • 4 MB shared L2 cache per cluster.
      • Twice the Vector & AI throughput.

  4. Xe2 GPU:

    • Lunar Lake features the new Xe2 GPU:
      • 8 Xe cores.
      • 8 Ray Tracing Units.
      • XMX support.
      • 8 MB dedicated cache.
      • Enhanced media & display capabilities.

  5. AI Compute Power:

    • Lunar Lake combines CPU, GPU, and NPU (Neural Processing Unit) capabilities.
    • A whopping 120 Platform TOPS:
      • 48 TOPS from the NPU.
      • 67 TOPS from the GPU.
      • Around 5 TOPS from the CPU.

In summary, Intel’s Lunar Lake promises exceptional performance, power efficiency, and AI capabilities. It’s a leap forward in SOC design, and developers can explore it further with the AI PC developer kit. 🌙🔥
