For the OS setup note that we do have the latest Spring 2020 (2004) Windows 10 update applied with all latest incremental OS updates. We are using the Ryzen “High Performance” power profile for the Ryzen 7 3700X, and we are using the Ryzen “Balanced” profile for the Ryzen 7 2700X. With the 2700X it doesn’t have a special AMD high performance profile, just the Balanced. However, in our testing using AMD’s Balanced profile versus Windows built-in High Performance produces higher benchmark results, so we stuck with AMD’s Balanced profile for the 2700X to get the highest possible performance.
Remember, the only difference in the benchmarks to come is the installation of either CPU on the exact same test bench setup. Nothing between the CPUs is different, except the CPUs themselves.
