Tom’s Hardware is reporting that AMD may be choosing to opt to only support DDR5 for its upcoming Socket AM5 motherboards. Nothing is yet official but Tom’s suggests that signs have been pointing towards that direction and sources corroborate this by stating that there are no provisions for DDR4 on upcoming chipsets.
AMD has not yet detailed their Ryzen 7000 CPUs if it supports both DDR4 and DDR5 or just DDR5. Still, the upcoming B650 and X670 motherboards will seemingly not provide DDR4 support and AMD has not disclosed this information yet aside from what’s already been announced which is DDR5 support.
The report further confirms the approach that AMD will be using for their high-end motherboard chipset with the X670 being a dual-chiplet design. This will fuse two B650 into one and provide all the I/O expected from a top-of-the-line motherboard.
The B650 and A620 chipset will be single chiplet and will feature PCIe Gen4 connection but PCIe Gen5 will be available on some AM5 CPUs.
Its expected that DDR5 prices could improve along the time that Ryzen 7000 and AM5 motherboards become available but anything could come up leading up to launch. With DDR4 also on its way out and AMD planning to utilize AM5 for another lengthy service life, leaving DDR4 behind may be one of those trade-offs.
AMD is expected to release Ryzen 7000 along with accompanying motherboards with the latest chipsets later this year.
