AMD’s upcoming Ryzen 7000 processors for desktops have been rumored for the past few months. While Lisa Su will introduce the Zen 4 again at CES 2022, the new AM5 platform is expected to feature multiple chipsets, just as AM4 has more than 500 motherboard lifetimes from the X370, X470, X570 and every chipset in between.
AMD announced the X670E, X670 and B650 chipsets during the AMD Keynote at Computex 2022., and this evening AMD announced its fourth chipset, the Ryzen 7000, the B650E chipset. The B650E chipset will work alongside the already announced B650 chipset, but since it’s part of AMD’s ‘Extreme’ series of chipsets, it will benefit from at least one PCIe 5.0 lane up to one M.2 slot, as well as additional support for PCIe 5.0. PCIe graphics slot, features not available on standard B650 boards.
during AMD’s keynote at Computex 2022, AMD CEO Lisa Su unveils three AM5 chipsets Designed to harness the power of 5nm Zen 4 cores in Ryzen 7000 processors. We already knew that the AM5 socket was built around a 1718-pin Lane Grid Array (LGA) socket, appropriately named LGA1718. Some of the significant benefits coming to AM5 include native PCIe 5.0 support from the CPU, not only for use with PCIe slots, but also for PCIe 5.0 memory, with the first consumer drives expected to be available in November 2022. .
AMD’s latest announcement of the B650E (Extreme) chipset provides motherboard vendors and users with a lower-cost platform option without sacrificing the longevity and expansion support of PCIe 5.0. The X670E chipset is reserved for the most premium models, such as the flagship The ASUS ROG Crosshair X670E Extreme motherboard was unveiled at Computex 2022.

Using PCIe 5.0 lanes requires a higher-end PCB, typically with more layers to maintain the signal integrity of the tracks, but this typically increases costs. The availability of the B650E chipset will allow vendors to use more expensive PCIe 5.0 lanes with more modest controller sets, allowing vendors to recoup costs. Ideally, it gives users a more expansive and future-proof platform to upgrade from, but without breaking the bank on unnecessary controller sets; Users who want the best set of controllers should choose the X670 or X670E.
This ultimately means that AMD will have a mainstream platform with PCIe 5.0 (B650E) as standard and a cheaper alternative with only PCIe 4.0 lanes to PEG and M.2 slots. AMD strongly encourages motherboard manufacturers to offer at least one PCIe 5.0 M.2 slot for storage on most of their boards, as this is one of the main advantages of AMD’s AM5 platform.
As announced by AMD, together we during the advance_PCs event, Ryzen 7000 desktop processors will be available on September 27 with both X670E and X670 chipset motherboards. Motherboards featuring the B650E and B650 chipsets will be available later in October.
