AMD Zen 4 architecture supports DDR5-5200 specifications
Although it is still a while before AMD launches a new generation of the Ryzen 7000 series based on the Zen 4 architecture, as the release time approaches, more news related to it flows out. AMD officials have already confirmed that the new generation of processors code-named Raphael will use a new AM5 socket (LGA 1718) and support dual-channel DDR5 memory, but did not confirm the specific frequency.
The Intel Alder Lake platform currently supports DDR5 memory with a frequency of 4800MHz, which is the most basic standard in the JEDEC specification. Recently, memory manufacturer Apacer disclosed the memory support of some of AMD’s upcoming processors in a technical article introducing DDR5 memory. It is shown that the desktop and server processors based on the AMD Zen 4 architecture, that is, Raphael and Genoa, both start with DDR5-5200 specifications, and once again confirm that they will not support DDR4 memory. This means that AMD’s DDR5 memory starting frequency will be 400MHz higher than Intel’s, which will also release a new generation of Raptor Lake this year, perhaps also increasing to DDR5-5200.
Recent reports indicate that AMD is preparing a new DDR5 memory overclocking technology called EXPO, which is EXTended Profiles for Overclocking, which will provide two different memory overclocking profiles for high bandwidth and low latency, in response to Intel’s XMP 3.0.
Apacer’s table also confirms some other information, such as the new generation of Ryzen and EPYC processors will be launched in the second half of 2022; AMD’s next-generation Ryzen Embedded V3000 SoC will also appear in the second half of 2022 and will use the Zen 3+ architecture instead of the Zen 3 architecture that was widely believed to be before; the new-generation EPYC processor code-named Genoa supports 12-channel DDR5 memory; Intel’s fourth-generation Xeon Scalable processor, Sapphire Rapids, will arrive in the third or fourth quarter of 2022.
