According to a prominent leaker @ExecuFix, AMD’s first run of Zen 4 CPUs will swap out the trusted AM4 platform for a newer AM5 socket. This platform will feature a LGA1718 form factor, meaning the 1718 connecting pins will be motherboard side (land grid array), as opposed to soldered onto the processor itself (pin grid array). The size should be in line with older Ryzen packages, measuring 40 by 40 millimeters.
The AM5 socket will bring support for DDR5 memory modules in dual-channel, while sticking to PCIe 4.0 interfaces. At least, that’s if ExecutableFix is spitting straight facts. Over at Intel, their upcoming Alder Lake generation appears to already be bringing support for PCIe 5.0, as well as DDR5. On that front, Intel might have some exclusivity when it comes to new interfaces, depending on when the both of these CPUs are to launch.
The apparently quite connected leaker had already spilled some details on the AM5 platform, when he went on to AMD’s processors themselves. A day later, @ExecuFix leaked the first reference image of a AM5 processor. This is supposedly a consumer oriented Zen 4 processor, stemming from AMD’s so-called Raphael generation.
Being an AM5 processor, the image of the CPU package clearly shows the 1718 CPU pads that should connect to the pins on the motherboard-side. Just like ExecutableFix promised, a day before. The image, together with earlier claims, could still be fake — but the leaker has already built up some credibility due to earlier leaks on AMD, that proved to be right.
According to ExecutableFix, the TDP of these Zen 4 packages could go up to 170 Watts. The “normal” ones should top out at 120 Watt, with “a special variant” going above and beyond. It’s still unclear how this would fit into AMD’s line-up.
Aside from the stronger pull in power, these Zen 4 processors should also support more PCIe 4.0 lanes. It might not be the still illusive PCIe 5.0, but 28 lanes of PCIe 4.0 should still net you more than enough bandwidth for high-end video cards and other PC hardware.
The Raphael series of CPUs set out to launch in 2022, the last time we saw believable leaks on AMD’s roadmap. It’s unclear whether those details are still relevant, as AMD has never publicly given any statements on Raphael, the AM5 platform, or many specifics on Zen 4.
