Summary According to Executable Fix, who apparently has a pretty good track record with AMD leaks, AM5 will have an LGA1718 socket. This means AMD CPUs and sockets will be physically more similar to Intel CPUs and sockets than before, with the pins on the motherboard socket instead of a PGA layout with the pins on the CPU, which AMD currently employs. AMDs LGA socket will have 18 more pins than LGA 1700, which Intel will use for Alder Lake. However, the AM5 socket will retain the 40 x 40 mm size of the current AM4 socket, according to Executable Fix. In the same thread, Executable Fix goes on the say PCIe Gen 5 will be limited to only EPYC Genoa CPUs on Zen 4. Intel is rumored to have PCIe Gen 5 on all Alder Lake chips. Quotes My thoughts If true, RIP PGA on consumer chips. I guess this could help fix the issue with the CPU popping out when taking off the stock cooler and bending pins. This means you'll also need to keep that socket cover now on future AMD motherboards in order to RMA it. I wonder why AMD would limit PCIe Gen 5 to only EPYC, maybe due to increased motherboard costs? Also, is it even possible for AMD to fit 387 more pins on the same size socket and CPU?

Zen 4 Raphael (first consumer Zen 4 chip) will support DDR5 (as expected), but unlike Intel Alder Lake, it will not also support DDR4. Raphael will have 28 PCIe 4.0 lanes, up from Zen 3's 24. The chips will have a 120W TDP, with a 170W special variant also possible. Executable Fix also leaked a picture of the LGA 1718 pads on the CPU. Here it is compared to LGA 1700 (Alder Lake socket):

Rumor: AMD to go LGA with AM5, PCIe Gen 5 limited to only EPYC CPUs for Zen 4 Update: More leaks
