Colleagues from Videocardz, citing an unnamed source, report that AMD is going to present three chipsets for socket AM5 motherboards at Computex 2022: X670E, X670 and B650. It is reported that the two older chipsets will not differ from each other in any way, but AMD has slightly different requirements for them, which will allow motherboard manufacturers to save a little with the regular X670.
The difference in requirements is that motherboards with X670E (Extreme) will be required to provide PCIe 5.0 lanes for graphics cards and m.2 SSD drives, while X670 requires PCIe 4.0 lanes, while 5.0 is already optional.
We remind you that this is not official information, and therefore we recommend that you take it with a grain of salt. AMD presentation at Computex 2022 scheduled for May 23
