The key thing to note with B550 is that, while the chipset supports current and future Zen 3 processors, the boards didn’t support Ryzen 2000 and earlier processors, or Ryzen 3000 APUs like the Ryzen 5 3400G-at least at launch. But note that refreshed X570S chipset/motherboards also do away with the fan issue, while also delivering the extra bandwidth of AMD's flagship chipset. Those who like their PCs to run silently will appreciate that the B550 chipset doesn’t require support for active cooling.

There are other considerations (and complications) if you’re choosing the best B550 motherboard, as well. So even the best B550 motherboards may not have as broad appeal as cheaper B450 options - though you’ll forego PCIe 4.0 with these lower-priced boards, which is a key selling point of AMD’s latest platforms, as well as now Intel with Z590/Rocket Lake. But many B550 motherboards - particularly the high-end models - surpass the price of many lower-end X570 motherboards. And overall, B550 prices are lower than their X570 counterparts. While there’s less bandwidth for multiple next-generation high-speed storage and graphics card setups with B550 compared to X570, it does deliver enough PCIe 4.0 lanes for the typical setup of a single speedy boot drive and graphics card. But now that we’re well more than a year out from the launch of B550, we know that AMD’s more mainstream AM4 platform delivers on at least one of those promises-PCIe 4.0. AMD’s B550 chipset arrived with anticipation of PCIe 4.0 support at low prices, given the high cost of most X570 boards and the appealingly low price of many previous-generation B450 motherboards. The Best B550 motherboard for your next AMD build might not be a B550 board at all.
