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, with motherboards often including 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 Gigabyte B550 AORUS Pro features a 12+2 power stage design utilizing 50 A stages from Vishay Semiconductor. BIOS flashback makes an appearance in the form of Q-Flash Plus, as well as Gigabyte's famed finned VRM cooling solution. For connectivity, the Gigabyte B550 AORUS Pro includes two M.2 slots, both with full coverage heatsinks, as well as 2.5 Gb/s LAN powered by Realtek. The Gigabyte B550 AORUS Pro has a lot going for it, so let's dive in and see if the performance lives up to the potential!
