AM4-lineups of ASRock & ASUS
Before we take a look at all the various features of the boards, we'll go through the line-ups of the major manufacturers. Biostar is only participating in this test with a single board and therefore we're not including them in this category.
ASRock sent us no less than seven socket AM4 motherboards, among which the cheapest test participant featuring the B350 chipset. The AB350M Pro4 only costs about 75 pounds and for this reason it is one of the simplest boards in terms of appearance. Corners were cut in places such as the network and audio chips. ASRock also stands out with two Mini-ITX motherboards: the Fatal1ty AB350 Gaming ITX/ac and X370 Gaming ITX/ac. Just like with the Fatal1ty X370 Gaming K4 and X370 Professional Gaming the manufacturer has given these boards a black-red colour scheme.
The X370 Killer SLI and X370 Taichi are odd beasts, with a black-white design that clearly stands out. It's surprising that the latter board offers a really good power supply, despite the fact that it's not aimed at overclockers.
ASUS sent us five Ryzen boards. They can be divided in three series. We tested the Prime X370-Pro from the mid-range Prime series, which is comparable in positioning to the Prime Z270-A from the Intel world. Without too many extras this board offers nearly all features that you'd want.
There are also two boards from the ROG Strix series, namely the X370-F Gaming and the B350-F Gaming. The appearance of these boards is drastically different compared to that of the Prime, as they feature an I/O shroud and RGB lighting, among other things. They've also invested more into the audio chips and the X370 version features a baseclock generator, which means that it can be set freely.
Lastly, ASUS offers two options from the ROG Crosshair VI series, for those that are interested in a high-end board. The Crosshair VI Hero features a baseclock generator, just like the X370-F, and it also stands out due to its large amount of USB ports. If you're a USB-device collector, this is the board to get. The Crosshair VI Extreme adds special water cooling features and another M.2 slot, however it's also significantly more expensive. A nice extra of both the CrossHair VI boards is that both the socket AM3 and AM4 mounting holes are present, which means that you can use all socket AM4 processor coolers without any problems. This feature is not present on any other AM4 board, however it's a very useful one!
