AMD’s Ryzen 7000 ‘Raphael’ and EPYC 7004 ‘Genoa’ from AMD to support DDR5-5200


When AMD hinted several weeks ago that its next-gen Ryzen 7000-series “Raphael” processors would have remarkable DDR5 overclocking capabilities, it didn’t really specify the capabilities. But it turns out that Raphael will support DDR5-5200 memory out of the box, according to Apacer, one of the leading memory module vendors.

Apacer recently published a chart (discovered by @momomo_us) describing the memory types supported by modern and upcoming processors from AMD and Intel. Intel’s Alder Lake and Sapphire Rapids processors support DDR5-4800 memory, as do AMD’s Ryzen 6000 “Rembrandt” APUs. Meanwhile, AMD’s Ryzen 7000 “Raphael” and EPYC 7004 “Genoa” processors based on the Zen 4 microarchitecture are said to support faster DDR5-5200 SDRAM.

DDR5-5200 memory modules will provide approximately 8.3% more peak memory bandwidth than DDR5-4800 DRAM sticks currently officially supported by Intel’s Alder Lake processors, so AMD’s next-generation desktop will have a slightly more advanced memory subsystem compared to Intel’s existing processors. . Meanwhile, given that DDR5-5200 meets JEDEC’s specifications for DDR5, it’s logical to expect Intel to support that speed in the future as well (after all, the table of ‘Apacer says nothing about the memory subsystem of Intel’s Raptor Lake processors).

While existing 12th Gen Intel Core “Alder Lake” processors officially support DDR5-4800 memory, as long as they are properly cooled they can handle memory data transfer rates of 8000 MT/s or more . To that end, it’s reasonable to expect AMD’s next-gen Ryzen “Raphael” processors to be at least as capable as Intel’s Alder Lake chips, so their DDR5 overclocking capabilities should be considerably more impressive than the out-of-the-box DDR5 support.

DDR5 was designed to provide significant performance and capacity upgrades over DDR4 memory, so over time DDR5 memory chips will gain in performance and capacity. At present, high-speed DDR5 modules are quite expensive, and it remains to be seen whether high-speed memory modules gain popularity with next-generation processors.
