Intel Socket LGA1851 Detailed, Partially Retains Cooler Compatibility
Igor’sLAB has revealed more information on Intel’s next-generation socket intended for Arrow Lake processors, the LGA1851. Some basic numbers: this socket will physically measure at the same size, at 37.5mm x 45mm which meant existing coolers will not require a new mounting system for installing future CPUs (however, there are caveats). The socket also gains 151 more pins from LGA1700 – home to Intel’s 12th Gen (Alder Lake), 13th Gen (Raptor Lake) and the upcoming 14th Gen (Raptor Lake Refresh) models.
However, there are some minor differences in Z-height (socket thickness) that may require some changes for coolers to properly fit onto these new CPUs. For one, the cooler pressure is now set to double from 489.5N to 923N of force. This meant that while existing coolers will be socket compatible, some may need additional washers or screws to meet the specified pressure required to maintain cooling performance.
As for why Intel opt to new socket for the Arrow Lake architecture and beyond – it is said that Intel wants to catch up on AMD in regards to I/O capabilities. AMD’s 600 series chipset is capable of delivering both PCIe 5.0 x16 to GPU and PCIe 5.0 x4 simultaneously; while Intel is slightly behind in this regard with no native PCIe 5.0 support for SSDs. The new platform is expected to at least match the I/O capabilities of Team Red in this regard.
However, the new platform will only arrive at late 2024, as Intel still has Raptor Lake Refresh waiting in the wings – which is expected to launch this October.
