During Intel’s recent Innovation event, CEO Pat Gelsinger shared exciting details about the upcoming Meteor Lake client platform. This marks a significant shift for Intel as they move away from the Intel 7 node and embrace Foveros 3D packaging with EUV lithography. Meteor Lake introduces a tiled, disaggregated chiplet architecture for Intel’s consumer chips, bringing advancements to the mobile market.

The compute tile of Meteor Lake features new P-core (Redwood Cove) and E-core (Crestmont) processors, promising improved IPC gains. One interesting addition is the Low Power Island E-core embedded in the SoC tile, allowing for more efficient handling of light workloads. Meteor Lake also includes a Neural Processing Unit (NPU) for on-chip AI capabilities.

Intel aims to enhance their position in the mobile market with Meteor Lake by improving compute core hierarchy, graphics capabilities with Xe-LPG Arc-based graphics, and AI advantages with the NPU. The Foveros 3D packaging will become a staple of Intel’s processor roadmap, with Intel 4 process acting as a stepping stone to future nodes like Intel 3.

Meteor Lake represents a revolutionary leap forward for Intel’s client processors. The architecture is built on Intel 4 with EUV lithography, offering improved power efficiency and area scaling. The use of EUV allows for better resolution and pattern fidelity in manufacturing. Enhanced Copper, a mixture of copper and cobalt, is used in Intel 4 to reduce resistance and improve power delivery.

The SoC tile in Meteor Lake introduces a Network-on-Chip (NOC) and Low Power Island E-Cores. The NOC improves bandwidth scalability and connects various components within the SoC. The LP E-cores are designed for power efficiency and handle lighter workloads. Power management is done through a scalable system with Power Management Controllers (PMC) on each tile.

Intel’s NPU in the SoC tile brings AI capabilities to Meteor Lake, supporting standardized program interfaces like OpenVINO. The NPU consists of two neural compute engines and offers flexibility for diverse workloads. It is compatible with Microsoft’s new compute driver model, MCDM.

The graphics tile in Meteor Lake features Intel’s Xe-LPG Arc-based graphics architecture. It promises 2x performance per watt compared to previous Xe-LP graphics. The Xe-LPG architecture includes 8 Xe graphics cores, 128 vector engines, and 8 Ray Tracing Units (RTU). The graphics and media elements are disaggregated from the graphics tile, allowing for power savings during encoding, decoding, and video playback.

The I/O tile provides additional connectivity features and varies depending on the processor’s grade and specific vendor needs. Thunderbolt 4 support is available on higher-end SKUs, while lower-end SKUs may omit certain I/O features to reduce costs.

Intel has focused on security with Meteor Lake, introducing the Intel Silicon Security Engine (ISSE) and partitioning the Converged Security and Manageability Engine (CSME) for enhanced platform security.

Overall, Meteor Lake represents a significant architectural transformation for Intel’s client processors. It combines advanced technologies like Foveros 3D packaging, EUV lithography, and AI capabilities to deliver improved performance and power efficiency in the mobile market. Specific SKUs and configurations are yet to be disclosed, but Intel plans to launch the first Meteor Lake Ultra SKU with AI capabilities on December 14th.
