Since most AMD X470 motherboards aren't significantly more expensive than the old X370 models, you'd prefer to combine a Ryzen 2 processor with a new motherboard. You're sure you'll be able to get started right away without BIOS updates for which you need an older CPU, and you'll also be able to take advantage of all the motherboard developments of the past year.
The latter is particularly noticeable in improved support for fast memory, more extensive RGB capabilities and, increasingly, an included heatsink for an M.2-ssd. Also things like the BIOS are a bit more refined than in the first generation.
AMD X470 motherboards with the best value for money
The AMD X470 motherboard with the best price-performance ratio is undoubtedly the Gigabyte X470 Aorus Ultra Gaming. This affordable motherboard is remarkably richly equipped, with high quality network and audio chips and all the features you want. Only if you want to start overclocking seriously you might want to look at a model with a somewhat heavier power supply.
Many models that are similarly or even significantly higher priced are actually no better or hardly any better than Gigabyte's price breaker. The first model that in our opinion offers clear added value is the Asus RoG Strix X470-F Gaming, mainly because of the heavier power supply and the integrated I/O-shield. The first makes it more suitable for overclockers and the second is the first time in this generation that we see a RoG Strix model, or Asus' semi-payable RoG subseries. As far as we are concerned, this trend should continue, because not only is it more convenient than placing a separate I/O-shield in your case and aligning everything correctly, but it also looks much nicer.
Socket AM4 on mini-ITX
With the mini-ITX signs based on the X470 chip set, we have a problem: we can't actually choose. The ASRock X470 Gaming ITX/AC and Asus RoG Strix X470-I Gaming are both top-notch in terms of components used and features provided, with excellent audio, good network chips, support for HDMI 2.0 and USB 3.1 on board.
Asus is three tenners more expensive than the ASRock, so you have to buy the latter, you might think. However, there are subtle differences that will more than compensate for that price difference for some potential buyers. Asus, for example, has opted for a heavier power supply and ingeniously accommodates an M.2-ssd in the front, which is cooled much better than the SSD slot on the back. In addition, all USB ports with Asus version are 3.0 or higher, with ASRock you still have to make do with two USB 2.0 ports. On the other hand, ASRock uses a more modern WiFi chip.
High-end X470: Polished, but not extreme
We are used to the fact that for Intel's mid-range socket also motherboards appear at five, six hundred dollars, but with AM4 the high-end segment already stops at about 300 dollars. Really extreme motherboards are not included, although you can certainly buy a luxurious and richly equipped AMD X470 motherboard. In terms of appearance, these more expensive boards stand out with extensive RGB lighting and an integrated I/O-shield - the latter is not only beautiful but also very handy. In addition, overclocking features such as an error code display and on-board buttons are standard here.
One of the high-end motherboards that appeals most to us is the Gigabyte X470 Aorus Gaming 7 WiFi. Compared to the cheaper models you get a much heavier power supply, excellent audio including a headphone amplifier and last but not least a high-end wifi chip, including Bluetooth 5.0 support.
The high-end model of Asus, the RoG Crosshair VII Hero WiFi, is quickly 50 dollars more expensive. The main added value of this motherboard is the huge number of usb ports (12 pieces!) at the back; only some Threadripper based motherboards have more. Moreover, with this motherboard you can use a second PCIe 3.0 x4 SSD (although it does prune off lanes from your video card) and the BIOS, including preset OC profiles, is also ideal for overclockers. The only downside to the new Hero is the somewhat older wifi chip, but we for now, we forgive it - and it won't be important for everyone.
Finally, the Asus RoG Strix X470-F Gaming, Gigabyte X470 Aorus Ultra Gaming and both ITX motherboards from Asus and ASRock will go home with an Excellent Choice award. The Ultimate Product Awards go to the Asus RoG Crosshair VII Hero WiFi (also available without Wi-Fi, for those who don't need it) and the Gigabyte X470 Aorus Gaming 7 WiFi.
Looking for a more affordable AM4 motherboard socket? Then it may still be worthwhile to wait for the AMD B450 motherboards, which are expected to be released at the end of this month.
