When AMD hinted a few weeks ago that its next generation of Ryzen 7000 series "Raphael" processors would have excellent DDR5 overclocking capabilities, it did not really elaborate on these capabilities. But it turns out that Raphael will support DDR5-5200 memory out of the box, according to the leading memory module vendor.

Apacer recently released a table (discovered by @ momomo_us) that describes what types of memory AMD and Intel's modern and upcoming processors support. Intel's Alder Lake and Sapphire Rapids CPU support DDR5-4800 memory, just like AMD's Ryzen 6000 'Rembrandt' APU. At the same time, it is said that AMD Ryzen 7000 'Raphael' and EPYC 7004' Genoa' processors based on Zen 4 microarchitecture support faster DDR5-5200 SDRAM.

The peak memory bandwidth of the DDR5-5200 memory module will be about 8.3% higher than the DDR5-4800 DRAM stick currently officially supported by Intel's Alder Lake processors, so AMD's next-generation desktop CPU will have more advanced memory subsystems than Intel's existing processors. At the same time, since DDR5-5200 complies with the JEDEC specification for DDR5, it is logical to expect Intel to support this speed in the future (after all, the memory subsystem of Intel Raptor Lake processors is not mentioned in Yuzhan's table).

Although Intel's existing 12-generation Core "Alder Lake" CPU officially supports DDR5-4800 memory, they can handle 8000 MT/s or more of in-memory data transfer rates as long as they are cooled properly. To that end, it is reasonable to expect AMD's next-generation Ryzen 'Raphael' CPU to be at least as powerful as Intel's Alder Lake chips, so their DDR5 overclocking capabilities should be more impressive than out-of-the-box DDR5 support.

DDR5 is designed to provide significant performance and capacity upgrades compared to DDR4 memory so over time DDR5 memory chips will further improve performance and capacity. At present high-speed DDR5 modules are very expensive and it remains to be seen whether high-speed memory modules will gain significant popularity in the next generation of processors.
