AMD’s AM5 platform will support DDR5 and PCIe 5 when it launches in 2022


AMD has confirmed that its new AM5 platform will support both PCIe 5.0 and DDR5 memory, and will land on our desktops in 2022. AMD released its first Ryzen processor five years ago and famously does this by getting Robert Hallock and John Taylor to sit down and discuss the architecture that has transformed AMD’s place in the CPU market.

It’s not as dry as it sounds, as AMD took the opportunity to confirm a few things: its 3D V-Cache chips are still on the way at the start of next year, and its AM5 platform from new generation will support the latest I / O and memory technologies.

After a quick trip down memory lane where Robert Hallock remembers the first time he got his hands on the first Ryzen processor, he goes on to say, “In 2022, Ryzen will have a new platform and some key ingredients are DDR5, PCI Express Gen 5, and cooler compatibility with existing AM4 coolers. “

AMD has been talking about DDR5 support for Zen 4 in slides for some time now, but hasn’t said if its next-gen platform will support PCIe 5.0. Confirming this now makes sense, if only because the 12th Gen Intel Alder Lake platform will ship with support for DDR5 and PCIe 5.0.

To be fair, it would have been surprising if AMD let its I / O lead slip away for a whole generation, given that it has supported PCIe 4.0 since the launch of Zen 2 in 2019, when Intel did not. took over the standard only this year. PCIe 4.0 may not have done much for graphics cards, but its impact on storage, along with PCIe 4.0 SSDs, has been profound and PCIe 5.0 doubles the available bandwidth. It is never a bad thing.

The last point that Hallock raised is also worth mentioning, as cooler compatibility is important for anyone looking to upgrade to Zen 4 as a PC platform when it launches. You’ll need a new motherboard and new DDR5 RAM, so being able to keep your CPU cooler means you should be able to save a bit of money and not have to wait for a company to release adapters.

We don’t have an exact date for when these chips will land, although given that the 3D V-Cache chips are going to be released at the start of the year, we can probably expect Zen 4 and AM5. decrease between July and November in 2022.
