On September 27, the Ryzen 7000 will be available. In addition, the manufacturer will introduce the AM5, a completely new platform. But, of course, anyone who mentions a new platform must also say a new chipset, so it seems to sense that AMD would be more open to the idea of using the AM5 to catch up to the competition on several fronts.
First, it switches sockets and substitutes PGA supports for the LGA that Intel has been using for a while. Similarly, AMD has chosen to enable DDR5 and PCI Express 5.0 to remain competitive.
There will be two suggested variants. While the X670 “in brief” can only support storage, the most costly model, the X670E, will offer PCIe 5.0 for storage and display. In reality, AMD intends to provide a little less expensive chipset, in addition to the X670/X670E, to design more approachable motherboards for regular people.
The existence of the B650/B650E was not a secret when AMD CEO Lisa Su unveiled the Ryzen 7000, but she did not provide any more information. However, we know that this second chipset will follow the X670/X670E on October 4.
Additionally, remember that the B650/B650E difference (E for Extended) is the same as for the X670: the former is restricted to PCIe 5.0 for NVMe storage, while the latter also links it to support for graphics cards.
