We updated the firmware for our Gigabyte B550 Aorus Master to the latest publicly-available revision. Windows 10 Professional 64-bit with October 2020 Update As usual, the trio needs to be on the same page for optimal operation, while breaking that synchronicity results in a heavy latency penalty that's detrimental to performance in some applications. The Infinity Fabric Clock (FCLK) continues to be in a permanent relationship with the unified memory controller clock (UCLK) and memory clock (MEMCLK) in a 1:1:1 ratio. That's an important consideration when selecting and tuning Ryzen's memory. On the memory front, Ryzen 5000 chips inherited the same I/O die and dual-channel memory controller as their predecessors, therefore, the mechanics remain unchanged. Ryzen 5000 wields AMD's latest Zen 3 cores that introduced important IPC gains, among other microarchitectural improvements. Four years later, AMD's foot is still on the pedal and taking the fight to Intel, with its latest army of Ryzen 5000 (codename Vermeer) processors leading the charge.

After being off track for a few years, the chipmaker ultimately found the winning formula with its Zen microarchitecture. It's not always easy to stay on the right path, and AMD, like any other company, has had its ups and downs.
