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.[4] Tim Wilson led the system on a chip development for this generation microprocessor.[6]

Background[edit]

In July 2021, Meteor Lake was initially announced to be coming with a 5–125W TDP range for various segments ranging from ultra low power mobile to enthusiast desktop.[7] The initial tape-in process for Meteor Lake took place in May 2021. The CPU compute tile was confirmed to be fabricated on Intel's 7nm process (since rebranded to "Intel 4").[8][9]

In October 2021, Intel said in an earnings call that it had taped out the CPU compute tile for Meteor Lake and after it was received it had powered on within 30 minutes and with expected performance levels.[10] In April 2022, Intel announced that an assembled Meteor Lake mobile processor had been powered-on for the first time in a development milestone.[11][12]

In March 2023, it was reported that Intel had decided to cancel development of high-end Meteor Lake-S processors for desktop.[13] Meteor Lake-S processors were being designed to fit into the LGA 1851 socket, which is identical in dimensions to LGA 1700, but the cancellation of desktop Meteor Lake meant that the LGA 1851 socket won't debut until Arrow Lake in 2024.[14] The top Meteor Lake-S SKU in development contained 6 Redwood Cove P-cores and 16 Crestmont E-cores, which is two fewer P-cores than the last generation Raptor Lake Core i9-13900K.

At Intel's Innovation event in September 2023, head of Intel's Client Computing Group Michelle Johnston Holthaus confirmed that some Meteor Lake-based processors would come to desktop in 2024. Intel later clarified that socketable desktop Meteor Lake processors would not be coming to the DIY market with the LGA 1851 socket.[15][16] Instead, Meteor Lake processors in a BGA package will be available on desktop in the form of compact all-in-one PCs.[17] A reason for this, according to a statement by Intel to ComputerBase, is that "Meteor Lake is a power efficient architecture that will power innovative mobile and desktop designs".[18]

Branding[edit]

Intel unveiled new branding in June 2023 for upcoming Meteor Lake processors after 15 years of using the same Core i branding. Core branding would be simplified by dropping the 'i' with processors branded Core 3, 5 and 7 instead.[19] The new 'Core Ultra' 5, 7 and 9 branding would be reserved for "premium" processors according to Intel.[20] In addition to the new tier naming, Intel said it would be de-emphasizing processor generations in marketing material, though the processor generation number would remain in the processor number.[21] Meteor Lake processors with Core Ultra branding are classified as first generation Core Ultra.

The new Core and Core Ultra branding was perceived as creating more branding confusion rather than reducing it.[22] Josh Loeffler of TechRadar wrote that "differentiation between Core and Core Ultra is also somewhat head-scratching, especially since there will at least be some overlap between the two brands" as Core 5 and Core 7 processors will exist alongside Core Ultra 5 and Core Ultra 7 processors.[23] In the view of Digital Trends, the new branding emulated AMD and Apple's naming conventions which amounted to Intel "chasing its competitors instead of leading the pack".[24]

Production[edit]

In April 2023, Meteor Lake and its "Intel 4" process were reportedly ramping to production.[25] Production on Meteor Lake with Intel 4 wafers took place at Intel's D1D fabrication facility in Hillsboro, Oregon.[26] The D1D fabrication facility has a total output of 40,000 wafers a month.[27] Secondary source production for Meteor Lake takes place at Fab 34 in the Republic of Ireland.[28][29] On September 29, 2023, Intel announced that Intel 4 products, including Meteor Lake, had entered high-volume production at Fab 34 in the Republic of Ireland.[30] The GPU, SoC and I/O extender tiles in Meteor Lake are manufactured by TSMC in Taiwan.

Unveiling and release[edit]

Meteor Lake was revealed at Intel's Innovation event on September 19, 2023 with the announcement that 'Core Ultra' branded processors would be launching on December 14.[31] However, no list of Meteor Lake SKUs were revealed at Innovation nor release details on regular 'Core' branded processors.[32]

Description[edit]

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.[33]

Intel uses several lithographic processes in the Meteor Lake processors.[34] 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.[35]

Features[edit]

A chiplet architecture with four tiles: compute, graphics, system on a chip and input/output.[4][36] 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.[37] It comes in a Type 3 FC-BGA2049 package.
