We tested all socket AM4 motherboards with an AMD Ryzen 7 1800X, 8GB of G.Skill Trident Z memory clocked at 2400 MHz, two OCZ Arc 100 240GB SSDs and a Seasonic Prime 650W 80+ Titanium power supply. Since our standard cooler wasn't capable of keeping the processors cool enough to prevent throttling, we used the Cooler Master MasterLiquid Lite 120. To top things off, we used the MSI GeForce GTX 1050 Ti as the GPU for our system.
All tests were performed using the default settings of the motherboards. Of course performance and power consumption depend on the standard tuning. Motherboard manufacturers used to regularly cheat by secretly increasing the bClk slightly. We, and other review sites, did not like this practice at all, however since then the various manufacturers have stopped doing this.
You can find all socket AM4 X370 motherboards we've tested so far in the graphs. The Biostar Racing X370GT3 can be recognized by the red bars, while the other X370 motherboards are represented by blue bars.
