Meteor Lake is Intel's codename for the first generation of Intel Core Ultra mobile processors,[4] and was officially launched on December 14, 2023.[5] It is the first generation of Intel mobile processors to use a chiplet architecture. Tim Wilson led the SoC development for this generation microprocessor.[6]

Description

According to Intel Technology Roadmaps and Milestones published on February 17, 2022. Meteor Lake features XPU (Intel's device abstraction for CPU, GPU, FPGA and other accelerators) enhancements with integrated AI and a tiled GPU architecture that, according to Intel, should deliver discrete graphics-level performance.[3] These statements were later confirmed on May 23, 2023 with additional details that emphasized Intel's collaboration with Microsoft on support of the new processor in Windows 11.[7]

Intel uses several lithographic processes in the Meteor Lake processors.[8] The compute tile is manufactured using the Intel 4 process, the graphics tile TSMC's N5 process, the SoC and I/O tiles TSMC's N6 process. The tiles are connected by Intel's Foveros[4] packaging technology.[9]

On June 15, 2023, Intel announced that beginning with Meteor Lake it would use new branding for the Intel Core processors:[10]

  • Letter i dropped from tiering (e.g. Intel Core 5 processor);
  • New processor numbering (the preferred method is to put the processor number after the word "processor", such as Intel Core 5 processor ##xx).

In this announcement, Intel mentioned that Meteor Lake would be exclusively mobile architecture for laptops, and processors on this architecture would be referred to as Core Ultra, while regular Core (desktops) would be on the Raptor Lake Refresh architecture.[11]

Features

A multi-chip module architecture with four tiles: compute, graphics, system on a chip and input/output.[12] Whereas a discrete Platform Controller Hub (PCH) chip was included in the package of previous generations of high-end laptop processors to provide I/O functions, those are integrated into the processor MCM itself for Meteor Lake.[13] It comes in a Type 3 FC-BGA2049 package.

CPU

  • Up to 16 cores:[14]
    • Up to 6 Redwood Cove performance cores (P-core)
    • 8 Crestmont efficient cores (E-core), 2 clusters with 4 cores
    • 2 low power Crestmont efficient cores (LP E-core) on the SoC tile
  • L1 instruction cache per P-core increased to 64 KB, up from 32 KB in Raptor Cove
  • 2 MB L2 cache for each P-core, E-core cluster and LP E-core cluster
  • Up to 24 MB shared L3 cache

GPU

  • Xe-LPG Graphics Architecture[15][16]
  • Up to 128 Xe Vector Engines (XVE)[17]
  • 8K 10-bit AV1 hardware encoder[18][19]
  • Up to 2.35 GHz frequency
  • FP64 native hardware support

NPU

  • Intel AI Boost NPU accelerator up to 1.4 GHz frequency
  • 4K MAC with each MAC capable of 1 fp16 or 2 int8 operations per cycle
  • 4 digital signal processors
  • 4 MB dedicated static memory
  • LeonRT frontend processor
