AMD 5nm Zen4 Ryzen 7000 will not supports DDR4 RAM

AMD has already officially announced that it will launch a 5nm process, Zen4 architecture Ryzen 7000 series processors in the second half of the year, support DDR5 memory, PCIe 5.0 bus, and switch to the new AM5 package interface.


However, AMD has not been clear, will it continue to support DDR4 memory at the same time?


Tom’s Hareware confirmed from multiple sources that the Ryzen 7000 series will only support DDR5 memory, at least when paired with X670 and B650 motherboards.


What is not clear is whether there is a possibility that the memory controller of the Ryzen 7000 series supports DDR4/DDR5 at the same time, and can continue to choose DDR4 memory when it is paired with a new generation of A series motherboards?


It seems that this possibility is very low at present, and there is no sign of a new generation of A-series motherboards on the roadmap, and I only hope to follow up in the later stage.


If this is the case, it will undoubtedly be a major disadvantage of the Ryzen 7000 platform: DDR5 memory is still expensive in the short term, and there is no obvious performance advantage over DDR4 memory. Only supporting DDR5 will undoubtedly greatly reduce the attractiveness of AMD’s new platform.


Even if an “A550” motherboard is added in the future to continue to support DDR4 memory, and forcing X670 and B650 motherboards to support DDR5, a lot of consumers will be discouraged.


You know, Intel’s Raptor Lake 13th-generation Core at the end of this year will still retain support for DDR4.


Another big change is the chipset.


Both X670 and B650 will be handled by Xiangshuo, an old partner, using TSMC’s 6nm process.


The B650 chipset connects to the Ryzen 7000 processor via PCIe 4.0 x4 lanes, but may support PCIe 5.0 for some models.


At the same time, it will provide eight PCIe 4.0 (half to M.2), four SATA , and a lot of USB.


The X670 will use a small chip design for the first time, which is equivalent to combining two B650s into one , and the specifications will naturally double, including sixteen PCIe 4.0, eight SATA, and more USB.
