Although DDR5 type memory was not all that happy when it was launched due to high pricing, today the context is no longer quite the same. Indeed, prices have dropped drastically since then and some kits are even affordable. And that’s good, since apparently Intel’s next socket will no longer support DDR4 memory.
For the 15th generation of Intel processors, a mandatory switch to DDR5 memory
As a result, no more DDR4 for the next Intel platform, but only DDR5 type memory. While AMD has already chosen to make DDR5 only with its AM5 socket, Intel, with its LGA 1700 socket, had chosen to do both, to improve the transition between the two standards.
The latter also claims that the LGA 1851 socket will remain Intel’s desktop platform until 2026. Recall that this LGA 1851 socket will be for the 15th generation of Intel processors.
Indeed, the CPUs we are expecting for October are of the 14th generation, they are the Raptor-Lake refresh and are still in the LGA 1700 socket. From the information we have, the size of the next socket does not change and the cooling systems should be compatible without modification on the LGA 1851.
The socket will have pins for up to 32 PCIe lanes – 16 to PEG, 8 to the DMI chipset bus, and two sets of 4 lanes to NVMe storage attached to the processor.
From these, the 16 PEG lanes and a set of 4 lanes should be Gen 5, while the chipset bus should remain DMI Gen 4 x8 and the second NVMe slot attached to the processor should be Gen 4.
The socket could Also feature cabling for display I/O, as Intel’s next-gen processors are expected to introduce iGPU updates.
