Big Picture: Intel Meteor Lake processors are reportedly moving to the 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 processors released this year perform surprisingly well even on five-year-old motherboards.

According to new rumorsIntel’s 14th generation desktop processors, codenamed Meteor Lake, will require the new LGA 2551 socket, meaning that current LGA 1700 motherboards will only support two CPU generations – as has been the case for quite some time – the current Alder Lake processors will follow Raptor Lake at the end of 2022.

The LGA 2551 will reportedly measure 38 x 46mm, making it 0.5mm wider and 1mm longer than the LGA 1700. Placing 50% more pins in the same area means the pin density will be much higher . It will likely be the company’s first platform to only support DDR5 memory.

Meteor Lake is expected to go on sale in the fourth quarter of 2023 and will include several new technologies being developed by Intel. It will introduce a new tiled architecture with TDPs ranging from 5W to 125W.

The compute tile will use the Intel 4 process node and debut a new architecture for both P-cores and E-cores. Meanwhile, the graphics tile will be built on the TSMC N3 node and will contain twice as many EUs as Alder Lake. Everything will be bundled together using Intel’s Foveros 3D packaging technology, which allows the chipmaker to stack tiles on top of each other.

Unfortunately, Intel only plans to switch sockets again after two CPU generations, as they did with the LGA 1200. By contrast, AMD has used socket AM4 in four generations of Zen processors (and some CPUs and APUs based on the Excavator microarchitecture). We recently verified The company launched the Ryzen 7 5800X3D on budget B350 motherboards back in 2017 and found the combination to work flawlessly.
