AMD Announces B650E Chipset for Ryzen 7000: PCIe 5.0 For Mainstream

Rumors surrounding AMD’s impending desktop Ryzen 7000 processors have been heating up for the past few months. Lisa Su announced Zen 4 at his CES 2022 but new his AM5 like AM4 has over 500 motherboard lifetimes from his X370, X470, X570 and all chipsets in between The platform was expected to include multiple chipsets.

AMD announced the X670E, X670 and B650 chipsets at the AMD keynote at Computex 2022 and this evening AMD announced the B650E chipset which is the fourth chipset for Ryzen 7000. The B650E chipset works side by side with the already announced B650 chipset, but being part of AMD’s “Extreme” series of chipsets, it is expected to have PCIe 5.0 lanes to at least one M.2 slot and , benefit from optional support for PCIe 5.0. PCIe graphics slot, a feature not available on the standard B650 board.

During AMD’s keynote at Computex 2022, AMD CEO Lisa Su announced three AM5 chipsets designed to harness the power of the 5nm Zen 4 cores inside the Ryzen 7000 processors. We already knew that the AM5 socket was based on the 1718-pin Lane Grid Array (LGA) socket, aptly named LGA1718. Key benefits brought to the AM5 include not only for use in PCIe slots, but also by way of PCIe 5.0 storage, which is slated to begin deploying the first consumer drives in November 2022. Includes PCIe 5.0 support. .

AMD’s latest B650E (Extreme) chipset announcement offers motherboard vendors and users a lower cost platform option, but without sacrificing PCIe 5.0 longevity and extended support. The X670E chipset is reserved for the most premium models, including the flagship ASUS ROG Crosshair X670E Extreme motherboard announced at Computex 2022.

Using PCIe 5.0 lanes requires a more premium PCB, usually with more layers so that the tracks can maintain signal integrity, but this usually comes at a cost. The presence of the B650E chipset allows vendors to use more expensive PCIe 5.0 lanes with cheaper controller sets, allowing vendors to offset costs. Ideally, it gives users a broader, more future-proof platform to upgrade from, but not spend money on a set of controllers they don’t need. Users who want the best controller set should opt for the X670 or X670E.

This ultimately means AMD will have a mainstream platform with PCIe 5.0 (B650E) by default and a lower cost alternative platform with only PCIe 4.0 lanes to the PEG and M.2 slots. . AMD is pushing motherboard vendors to provide at least one PCIe 5.0 M.2 slot for storage on most boards as this is one of the main advantages of AMD’s AM5 platform.

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