A while ago we reviewed the first socket AM4 mini-ITX board that reached our test lab. ASRock is the second manufacturer with an ITX model for AMD Ryzen and they immediately sent us two boards: the Fatal1ty AB350 Gaming ITX/ac and X370 Gaming ITX/ac. Which one should you buy if you're building a small-size Ryzen build?
Ryzen on an ITX board remains a special story. At Ryzen's launch, back in March, AMD announced a special X300 chipset for such boards, however we've yet to hear anything about the chipset since then. At Computex, in June, several manufacturers decided to release ITX boards based on the regular chipsets and they're slowly becoming available now.
One of the two ASRock boards that we're discussing today, the AB350 Gaming ITX/ac, is priced directly against the Gigabyte AB350N-Gaming WiFi. Not only are they very similar in terms of their naming, but the MSRP is also nearly identical. This will make for an interesting battle. The second board is based on the more expensive X370 chipset and is therefore about 25 pounds more expensive. Of course we'll also find out whether the higher price of the second board is justified or not.
On the next page we discuss and compare both motherboards extensively.
