Intel Meteor Lake: Redwood Cove and Crestmont confirmed

Meteor Lake, the 14th generation of core processors, will get Redwood Cove-type P-cores and Crestmont-type E-cores. This is now confirmed by logs from Microsoft Perfmon. This was first mentioned in November 2020 by the Youtuber “Moore’s Law ias Dead”. Meteor Lake’s first die shots were already over IEEE Symposium on VLSI Technology & Circuits been leaked. With regard to the Meteor Lake CPUs, which should replace Raptor Lake in 2023, there is talk of a structure made up of several individual chips, as AMD has been using for years. An interposer should therefore accommodate a SoC, an IO, a GPU and a CPU chip.

Meteor Lake: Die shot showing the first look at the compute tile

According to the slides at the time, Intel 4, formerly known as 7 nm, should allow at least 20 percent higher clock rates with identical consumption and, at least for computing circuits, scaling by a factor of two. Concrete key data are also mentioned. For example, the distance between two transistor fins should shrink from 34 to 30 nanometers. The many changes are also accompanied by a new socket, which should probably be called V1 – or better LGA1851. The BGA model is said to have 2,551 contacts. The dimensions will remain the same.

One of the highlights should also be the GPU. It is said to be a Xe-LPG with 128 to 192 execution units – depending on the source. There may also be two models – a more powerful GPU on laptops is conceivable. Otherwise it stays with DDR5 and PCI Express 5.0; for Intel, the challenge will primarily lie in the chiplet/tile design and the Foveros packaging. The tiled technology allows Intel more flexibility in the compilation than with Alder Lake (Gen 12) and Raptor Lake (Gen 13).
