Intel Socket LGA1851 Only Supports DDR5 Memory
Intel's upcoming desktop platform based on Socket LGA1851 will retire support for the DDR4 memory standard. The socket will only support DDR5. With this, Intel would have gracefully transitioned the market from DDR4 to DDR5, with its current Socket LGA1700 that enables both memory stardards, having supported three generations of Core processors (12th thru 14th). Leaf Hobby, a reliable source with Intel leaks, says that LGA1851 will remain Intel's desktop platform till 2026.
LGA1851 is expected to debut with the company's Core desktop processor generation that succeeds 14th Gen "Raptor Lake Refresh." The socket itself has the same dimensions as LGA1700, and is expected to be cooler-compatible with the older socket. The socket will feature pins for up to 32 PCIe lanes—16 toward PEG, 8 toward DMI chipset bus, and two sets of 4 lanes toward CPU-attached NVMe storage. From these, the 16 PEG lanes, and one set of 4 lanes are expected to be Gen 5, while the chipset bus is expected to remain DMI Gen 4 x8, and the second CPU-attached NVMe slot is expected to be Gen 4. The socket could also feature wiring for updated display I/O, as Intel's next-gen processors are expected to introduce updates to the iGPU.
