The B450 motherboards for AMD Ryzen have launched and we have the GIGABYTE B450 AORUS Pro Wifi for review, thanks to GIGABYTE and AORUS. There has been some controversy the last couple of weeks around this model marketing wise (it has been updated) but today we will test directly how this model performs under heavy tests, to give a reliable opinion for this product.
In addition, we will see what update the B450 chipset brings to the final consumer, in comparison to B350 and talk in-depth about Precision Boost Overdrive. Prepare your cup of tea, since it will be longer than our usual reviews.

1). Chipset B450 and specifications
The new 450 chipset brings many new motherboard models to the market. To the end user, the most important feature of these new sets of mobos, is the improvement of designs in many different aspects a motherboard has. Things like: a better VRM phase (in some cases), native support for Ryzen 2000 series without needing BIOS update and in general terms, a better product compared to what B350 motherboards offered.
Aside of these improvements, there is two main technology differences between B350 and B450, which are:
-Precision Boost Overdrive (Compatible with 2000 series Pinnacle Ridge CPUs).
Precision Boost Overdrive: We will have an in-depth section exclusively to define what is Precision Boost Overdrive (PBO), but to sum it up for now, it’s a way to “overclock” (although not technically) to obtain more performance from Pinnacle Ridge CPUs. It is very easy and practical and it is a feature that it is exclusive for 400 series motherboards (although you might find some high-end 300 series motherboards with modded BIOS with the option enabled).
StoreMi: This is AMD response to Intel Optane, although it works in a different fashion. It is kind of like Optane, since it, “accelerates” writes and reads on storage. It differs from Optane because StoreMi works as Tiered-Storage through software (a total different approach) and it needs two devices to make it work (a mechanical hard drive + a SSD).
This feature will need future testing but from what I have read, it has received positive feedback from the community. StoreMi will probably receive more attention with the launch of the new B450 chipset since it will become more mainstream.
On 400 series motherboards StoreMi is free (there is some few restrictions though) and in case someone has a 300 series motherboard, it has a 20 USD fee for those who want to access AMD’s StoreMi software.
Let us see the important parts of the motherboard using this diagram plus other technical data relevant to this review.
