A sizzling potato: With AMD’s next-generation Ryzen 7000 processors and AM5 socket arriving later this 12 months, the corporate has spent a variety of time not too long ago bragging in regards to the platform’s DDR5-memory efficiency. It appears this might be as a result of Zen 4 will launch with help for under the most recent reminiscence format slightly than providing it alongside a DDR4 possibility, as Intel does.
The launch of the AM5 socket will, like Intel’s Alder Lake, carry help for each DDR5 reminiscence and PCIe 5.0. But not like staff blue, which affords the choice of 600-series motherboards that help both DDR4 or DDR5, long-running rumors recommend AMD would possibly restrict consumers of Ryzen 7000 CPUs to the latter.
Editor from @ComputerBase posted this already few days in the past of their discussion board.

Backing up these claims is a brand new report from Tom’s Hardware, whose sources say X670 and B650 motherboards haven’t any provisions for DDR4 help. That’s not one thing most individuals wish to hear, provided that DDR5 reminiscence modules stay costlier and more durable to search out than their DDR4 counterparts whereas providing little profit in most video games; take a look at our personal reminiscence scaling and DDR4 vs. DDR5 benchmarks for Alder Lake guides.
AMD has been speaking up Zen 4’s talents on the subject of DDR5 overclocking. AMD Memory Enabling Manager Joseph Tao mentioned the platform would make a “massive splash” on this space, providing speeds that customers thought weren’t attainable.
Some are holding out hope that Ryzen 7000’s reminiscence controllers will help DDR4. If this does grow to be the case, AMD might supply DDR4 help on among the lower-end A-Series motherboards, however do not maintain your breath on that one.
Separately, Tom’s additionally reviews that AMD will use a dual-chiplet design on the X670 platform, thereby doubling the connectivity choices, whereas B650 and A-series motherboards and can function a single chipset chip.
The determination to go DDR5-only, assuming it’s true, is unlikely to be welcomed by the vast majority of customers. Whether Zen 4 can get extra out of the most recent reminiscence kind, or if costs and availability enhance earlier than Ryzen 7000 lands, stay to be seen.
