Instead of LGA 2551, the new socket for desktop Arrow Lake and Meteor Lake-S series processors is LGA 1851. The 2551-pin version might be a BGA variation for other series, but it’s unlikely to be utilized for a desktop LGA socket, according to today’s leak. The 2551 pin socket is presently not specified by Intel product planning for desktop series, according to Benchlife, however, it may be utilized by BGA packed devices in the future.
The LGA-1851 is the same size as the LGA1700/1800 for the Alder/Raptor Lake series, measuring 45 x 37.5 mm. As a result, it’s reasonable to expect that cooler compatibility will be kept.
The only measurement that has altered, according to the slide provided by the site, is the height of the IHS (integrated heat spreader). From 6.73-7.4mm to 6.83-7.49. Although this is not a significant modification, it may necessitate the use of new compatibility fasteners or additional care when installing the coolers. The taller box might be due to Intel’s new tiling architecture, which is based on Foveros packaging technology, which is used in the Meteor Lake desktop series. This is not the case with desktop Alder Lake/Raptor Lake CPUs, which are monolithic.
