Big picture: Intel's Meteor Lake processors are expected to move to a new socket, forcing Alder Lake owners to also buy a new motherboard if they want to upgrade. This is in stark contrast to AMD's AM4 platform, where this year's CPUs perform exceptionally well even on 5-year-old boards.

According to new rumors, Intel's 14th generation desktop processors, codenamed Meteor Lake, will require a new LGA 2551 socket, which means that current LGA 1700 motherboards will only supports two CPU generations - as has been the case for a while. The current Alder Lake CPUs will be followed by Raptor Lake in late 2022.

According to the report, the LGA 2551 will measure 38 x 46 mm, 0.5 mm wider and 1 mm longer than the LGA 1700. Fitting 50% more pins in a similar footprint means density legs will be much taller. It could also be the company's first DDR5-only platform.

Meteor Lake is expected to launch in Q4 of 2023 and will feature some of the new technologies Intel is developing. It will introduce a new tiled architecture, with TDPs ranging from 5W to 125W.


The computing tile will use the Intel 4 processor node and launch new architectures for both P cores and E cores. Meanwhile, the graphics tile will be built on TSMC's N3 node and feature EU numbers, twice as much as Alder Lake. Everything will be fused together using Intel's Foveros 3D packaging technology, allowing chipmakers to stack them on top of each other.

Unfortunately, Intel plans to change sockets after just two more CPU generations, just like it did with the LGA 1200. In contrast, AMD has used socket AM4 on four generations of Zen processors (and some CPUs and The APU is based on the Excavator microarchitecture). We recently tested the company's Ryzen 7 5800X3D on a budget B350 motherboard released in 2017 and found that the combination worked perfectly.
