Intel released the 12th generation Core processor Alder Lake at the end of November last year, the first DDR5 and PCIe 5.0 support, AMD also followed up at last week's CES exhibition, Ryzen 6000 series processors also support DDR5 memory, the end of this year's 5nm Zen4 also put DDR5 as the focus.
Considering the memory upgrade, Intel is actually compatible with DDR4 and DDR5 memory on the 12th generation Core, and even the 13th generation Of Core Raptor Lake series at the end of this year has not given up DDR4, which will also support DDR4/DDR5 standards.
In contrast, AMD is much more aggressive on DDR5, there is no DDR4 on the Ryzen 6000 series processor, the 5nm Zen4 architecture of the Ryzen™ 7000 series will upgrade the AM5 socket, the PPT also only mentions DDR5 memory support, DDR4 is not traced.
Ryzen 6000 is mainly for the notebook market, PC brands can purchase a large number of DDR5 memory, do not support DDR4 can also understand, but Zen4's AM5 platform to face the consumer market, now DDR5 memory price compared to DDR4 double or even double, while there is not much spot supply, which is very troublesome.
The embarrassment of desktop DDR5 memory even AMD itself is also very clear, the company's representative also mentioned in a video interview with the media that the promotion of the AM5 platform depends on the price and popularity of DDR5 memory.
It is reasonable to say that the Ryzen 6000 and Ryzen™ 7000 series are compatible with DDR5 and DDR4 without any technical problems, and AMD has not had a similar transition plan before, and I don't know why this time is more aggressive than Intel.
