For those who are waiting for the AMD Zen4 desktop processor (Ryzen 7000 series) and planning to upgrade, be prepared to replace the three major items at the same time.

In addition to the CPU itself and the motherboard with the new AM5 slot (LGA1718 interface), I am afraid that the only choice for memory is DDR5.

There have been multiple sources saying that Zen 4 has given up support for DDR4, and only supports DDR5. Now, the news has been confirmed by Apacer, a major memory module manufacturer.

According to Apacer's memory compatibility document, both AMD Zen 4 desktop and server chips (EPYC Genoa) will support up to DDR5-5200 memory, which is 400MHz higher than the 12th-generation Core's up to DDR4-4800.

This specification map should be trusted. After all, the Zen3+ Ryzen 6000 mobile processor that appears in it shows that it supports DDR5-4800, which is actually consistent.

Some friends may worry about the high cost of DDR5 memory installation. I think it can be solved from the following perspectives-

First, the performance of the new platform is definitely a qualitative change. Second, DDR5 memory will be the mainstream in the next few years. Use it early and enjoy it early. Thirdly, the minimum capacity of DDR5 starts from 8GB, so it should not simply be compared with the lowest price of DDR4. Finally, It is said that the Ryzen 7000 will integrate a GPU unit this time, and friends who are not demanding can save thousands of graphics card money.
