We will test our usual benchmarks with stock settings and using Precision Boost Overdrive enabled, to see how much difference is between one and the other. I would suggest reading the PBO section if you have not and how to apply (our way). Here are the PC specs:
CPU: Ryzen 7 2700X (Stock & PBO -90mv)
Motherboard: GIGABYTE B450 AORUS Pro Wifi
RAM: G.Skill Trident Z RGB 3200 MHz CL14
Graphics card: Nvidia GeForce GTX 1080 Ti
Cooler: EVGA CLC 280 (1500 RPM)
PSU: GIGABYTE G750H 750w 80 Plus Gold Certified
OS: Windows 10 Home 1803
Nvidia Driver: Hotfix 398.46
The results between the X470 AORUS Gaming 7 Wifi and the B450 AORUS Pro Wifi are close by in most of the cases. If there are some differences, take into account that we used an early BIOS with the X470 board and there has been updates regarding AGESA code. The B450 AORUS Pro Wifi F2b BIOS is using AGESA Pinnacle Pi 1004.
The benefits of using PBO can be seen on the benchmarks. We will discuss if we recommend using PBO with this motherboard at the end of the review. We will put the game captures of the CPU frequency PBO enabled/disabled, for those who might have skipped the previous sections.
