AMD Publicizes B650 Excessive Chipset for Ryzen 7000: PCIe 5.0 For Mainstream

Over the past few months, rumors surrounding the upcoming AMD Ryzen 7000 processor for desktops have gone into overdrive. Although Lisa Su launched the Zen 4 back at CES 2022, it was anticipated that the new AM5 platform would include multiple chipsets, just as the AM4 has over 500+ motherboard lifespans starting with the X370, X470, X570, and every chipset in between.

AMD announces X670E, X670, and B650 chipsets during AMD Keynote at Computex 2022, and tonight, AMD has announced the fourth chipset for the Ryzen 7000, namely the B650E chipset. The B650E chipset will run alongside the already announced B650 chipset, but because it is part of AMD’s ‘Extreme’ chipset series, it will benefit from PCIe 5.0 lanes to at least one M.2 slot, as well as optional support for PCIe 5.0 to graphics slots. PCIe, a feature not available with standard B650 boards.

During AMD Keynote at Computex 2022, AMD CEO Lisa Su launches three AM5 chipsets designed to harness the power of the Zen 4 5 nm core in the Ryzen 7000 processor. We already know that the AM5 socket is based on a 1718 pin Lane Grid Array (LGA) socket, which is named LGA1718. Some of the significant benefits that come to AM5 include native PCIe 5.0 support from the CPU, not only for use with PCIe slots, but also in PCIe 5.0 storage mode, where the first consumer drives are expected to launch in November 2022.

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

Using PCIe 5.0 lanes requires a more premium PCB, usually with more layers allowing the tracks to maintain signal integrity, but this usually adds to the cost. The presence of the B650E chipset will allow vendors to use the more expensive PCIe 5.0 laning with a simpler controller set, allowing vendors to offset costs. Ideally, this would give users a broader and more future-proof platform to upgrade, but without breaking the bank on unnecessary controller sets; users who want the best set of controllers should opt for the X670 or X670E.

This ultimately means that 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 the PEG and M.2 slots. AMD strongly encourages 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 during the event with us advancing_PC, the Ryzen 7000 processor for desktop will launch on September 27, with motherboards from the X670E and X670 chipsets. Motherboards featuring the B650E and B650 chipsets will be available for purchase at a later date in October.
