AMD Announces B650 Extreme Chipset for Ryzen 7000: PCIe 5.0 for Consumers

Over the past couple of months, the rumor mill surrounding AMD’s impending Ryzen 7000 processors for desktops has been in overdrive. Although Lisa Su unveiled Zen 4 at CES 2022, it was expected that the new AM5 platform would include multiple chipsets, just as AM4 has a lifespan of more than 500 motherboards of X370, X470, X570 and all intermediate chipsets.

AMD announced its X670E, X670, and B650 chipsets during the AMD Keynote at Computex 2022, and tonight AMD announced a fourth chipset for 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 get PCIe 5.0 lanes to at least one M.2 slot, as well as a socket optional PCIe 5.0 support for one PCIe graphics slot, features not available with standard B650 cards.

During AMD’s Keynote at Computex 2022, AMD CEO Lisa Su unveiled three AM5 chipsets designed to harness the power of its 5nm Zen 4 cores in Ryzen 7000 processors. AM5 was based on a 1718-pin Lane Grid Array (LGA) socket, aptly named LGA1718. Some of the significant benefits brought to AM5 include the processor’s native PCIe 5.0 support, not only for use with PCIe slots, but also for PCIe 5.0 storage, where the first consumer drives are expected to start rolling out in November 2022. .

AMD’s latest announcement of the B650E (Extreme) chipset gives motherboard vendors and users the option of a lower-cost platform, but without sacrificing longevity and support for motherboard expansion. PCIe 5.0. The X670E chipset is reserved for its most premium models, such as the flagship ASUS ROG Crosshair X670E Extreme motherboard, unveiled at Computex 2022.

Using PCIe 5.0 lanes requires a higher-end PCB, usually with more layers, which allows the tracks to maintain signal integrity, but usually adds cost. The existence of the B650E chipset will allow vendors to use more expensive PCIe 5.0 laning with more modest controller sets, allowing vendors to offset the cost. Ideally, it gives users a larger, more scalable platform to upgrade to, but without breaking the bank on unnecessary controller sets; users wanting the best sets of controllers should opt for X670 or X670E.

This ultimately means AMD will have a mainstream platform that has PCIe 5.0 by default (B650E) and a lower-cost alternative with only PCIe 4.0 lanes to PEG and M.2 slots. AMD strongly urges motherboard vendors to offer at least one PCIe 5.0 M.2 slot for storage on most of their boards, as this is one of the key benefits of AMD’s AM5 platform.

As announced by AMD at its Together we advance_PCs event, the Ryzen 7000 desktop processors will launch on September 27, along with both X670E and X670 chipset motherboards. Motherboards with the B650E and B650 chipsets will be available for purchase later in October.
