B650 and B650E are AMD's mainstream AM5 chipsets. Both use the AM5 socket and DDR5 memory, and both support Ryzen 7000, 8000 and 9000 desktop CPUs after a BIOS update, right up to the Ryzen 7 9800X3D. The main split is PCIe 5.0: a plain B650 usually runs its graphics slot at PCIe 4.0 with a PCIe 5.0 M.2 slot for storage, while B650E (the 'E' is for Extreme) adds full PCIe 5.0 to the primary GPU slot as well. Every B-series board allows CPU and memory overclocking with EXPO, so the real differences between models are VRM quality, M.2 slot count, networking and rear I/O.
For most gaming builds a well-specced B650 board is plenty; step up to B650E only if you want PCIe 5.0 headroom on the graphics slot. Match the board size to your case (ATX, micro-ATX or mini-ITX), look for a stronger VRM if you plan to run a Ryzen 9 chip, and confirm Wi-Fi and USB-C if your build needs them.
