Appreciating the premium nature of the Crosshair VIII Hero WiFi pricing, we have paired it with the current best-in-class Ryzen 9 3900X CPU. Offering context, we have it up against a last-gen Ryzen 7 2700X and decent X470 board from MSI.

The purpose is to show the performance uptick when you take the best of one generation and compare it against its direct predecessor.

Interestingly, we updated the Asus board's BIOS to 0702 prior to testing, which enables slightly higher sustained turbo frequencies than shown in the CPU review. Power consumption, as you will see, goes up a bit, as well.
