Introduction

Last year, AMD released the Ryzen 3000 series desktop processors in one of the most monumental hardware launches of the modern era. This final step completed the Red brand's ascent back into the forefront of the desktop processor market that began with the launch of the first generation of Ryzen CPUs.

With the Ryzen 3000 launch came the AMD X570 chipset. Featuring PCIe 4.0 support, X570 was an impressive leap from generations past. It was also hot, which had motherboards often include chipset cooling fans, and, more significantly, expensive. The high cost of the chipset increased the average cost of X570 motherboards considerably over previous generations.

While AMD has done a great job of maintaining motherboard compatibility with new generation processors, none of the previous-generation AM4 motherboards featured official PCIe 4.0 support, not even from the storage and PCIe controlled by PCIe 4.0 compatible CPUs. Enter B550, the more value-oriented little brother of X570. While the B550 chipset is PCIe 3.0 only, B550 motherboards support PCIe 4.0 from the CPU to the primary PCIe slot as well as the primary M.2 slot (dependent on a PCIe 4.0 ready CPU).


The ASRock B550 Taichi features a powerful VRM solution and a 16 power stage design utilizing 50 A stages from Vishay Semiconductor. The ASRock B550 Taichi even includes 2.5 Gb/s Ethernet using Intel's new I225-V controller, as well as dual PCIe 4.0 slots. Coming in at the same price as its older X570 Taichi brother, does the ASRock B550 Taichi have what it takes to compete with X570?
