AMD to Move from PGA to LGA 1718 Socket w/ AM5; Only Zen 4 Server CPUs to Get PCIe 5.0 Support

According to the latest info from the rumor mill, AMD’s AM5 socket will adopt the LGA 1718 design (from PGA on AM4 and AM3+). This means that similar to Intel sockets, AM5 will come with the pins on the socket rather than the processor, resulting in fewer incidents of chip destruction. The Zen 4 based Ryzen 6000 (or 7000) CPUs will feature 1718 pins, slightly more than 1700 on Intel’s LGA1700 socket meant for Alder Lake-S.

Furthermore, AM5 will come with support for quad-channel DDR5 memory which is essentially the equivalent of dual-channel DDR4. Keep in mind that DDR5 is going to split the number of memory channels per DIMM into two 32-bit rather than a single, wider 64-bit channel. Lastly, the first generation of chipsets (600 series) based on AM5 will be limited to PCIe 4.0 rather than the newer PCIe 5.0 interface. The latter will only come to the server-class Genoa processors. In comparison, Intel is promising PCIe 5.0 support on its LGA1700 socket for Alder Lake-S. Although this won’t have any real-world consequences, it’ll be an added marketing point for the latter. The socket size for AM5 is also supposed to the same as AM4 at 40×40 mm, so we expect existing CPU coolers to retain compatibility with the new socket.
