According to Channel Gate, the company has stopped supplying B650 silicon. Motherboard vendors have been told to clear out existing stock and move fully to the AM5 800-series chipsets, such as the B850 and its cut-down sibling the B840. Partners are expected to finish flushing their inventories by October, though retail shelves will probably take a bit longer to catch up.

Launched in October 2022, the B650 family was supposed to be the budget option for AM5 at around $125 to $150. In practice, boards were priced higher before drifting down into the sub $100 bracket. That value proposition did not last, and with Ryzen 9000 CPUs baked into BIOS support out of the box, AMD clearly thinks it is time to tidy up its lineup.

The key difference is PCIe 5.0. On B650 boards, it was up to manufacturers whether they included PCIe 5.0 lanes. On the B850, support is mandatory, with the B650E sitting closer to the new X870 (non E) spec by offering 24 full lanes.

B850 motherboards are already on sale at roughly the same prices as B650 boards, around $100 to $130 in the US. That makes the older chipsets look dated fast, especially as newer boards ship with higher memory frequency support and updated features.

Despite AMD’s spring cleaning, the B650 range is not instantly obsolete. Thanks to AMD’s long-term socket policy, older 600-series boards can still run Ryzen 9000 and even 9000X3D chips without drama. That gives them decent resale value, even if AMD would prefer everyone jump on the 800-series bandwagon.
