For those looking to build a Ryzen 7 3700X or Ryzen 7 3800X system in 2019, you will likely encounter the two following questions. 1. Do I go for an X570 motherboard which utilises the new PCIe 4.0 and designed for the new Ryzen 3000 processor? Or 2. Do I build a Ryzen 7 3700X system using a previous generation X470 or B450 motherboard, all of which are compatible with the new Zen 2 processors by AMD?
Each option will have their own benefits and drawbacks, such as building a Ryzen 7 3700X PC with an X570 motherboard you are future-proofing your build, and benefitting from the blisteringly fast new PCIe 4.0 interface, however, X570 motherboards are priced very steep in comparison to the older chipsets. Opting for a B450 motherboard or X470 motherboard for Ryzen 7 3700X or 3800X, you are able to pick from a range of cheaper, more tested motherboards where the VRM quality and performance is well known already – so you know what you are buying.
All B450 and X470 chipset motherboards, as well as select X470 and B350 motherboards will support Ryzen Zen 2 processors, and all they will require for them to become compatible is a BIOS update. With that said, it’s likely if you are going to build a 3700X or 3800X system with a B450 or X470 motherboard, you may need a motherboard with a BIOS Flashback built-in since you will need to update the BIOS to support the Ryzen 7 3700X or Ryzen 7 3800X.
Although the X570 chipset will be the latest generation chipset, personally if we were to be building with the Ryzen 7 3700X and didn’t really plan on doing any large overclocking of the 3700x, we would go for a B450 or X470 motherboard for Ryzen 7 3700X builds. If you do plan on overclocking, we will likely advise waiting for reviews to know which motherboards, both B450, X470 and X570, perform best during overclocking. I will still give my motherboard recommendations for overclocking the new Ryzen 7 3700X and 3800X. If you are still working out whether to pick the 3700X or 3800X, I recommend reading this guide here.
The new Ryzen 7 3700X and 3800X has far more efficient power consumption and thus lower TDP (65W) than the second generation of Ryzen. For example, an overclocked Ryzen 7 3800X will consume less power than a relative overclocked Ryzen 7 2700X. With that said, any B450 or X470 motherboard capable of housing an overclocked Ryzen 7 2700X will be more than capable for the new Ryzen 7 3700X and 3800X, even with overclocking.
With this in mind, I am going to overview the best motherboards for Ryzen 7 3700X & Ryzen 7 3800X builds, drawing from not just X570 chipset motherboards but also the B450 and X470 chipsets that also support the new Ryzen 3000 processors including the Ryzen 7 3700X.
Best Motherboards for Ryzen 7 3700X and 3800X – My Recommendations
Best Budget B450 Motherboard for Ryzen 7 3700X
The B450 chipset motherboards have been discussed to be more than capable for the Ryzen 7 3700X, with great VRM quality and design for an affordable price, especially from the likes of MSI. If you’re not looking to overclock the Ryzen 7 3700X and want a more than capable budget B450 motherboard for the 3700X, we would recommend the MSI B450M Mortar.
The B450M Mortar is a fantastic micro-ATX motherboard that has a fantastic VRM of the previous generation B450 chipset, and has been highly rated from top reviewers such as ‘Buildzoid’ – and many VRM Tier lists say the B450M Mortar sufficient for high OC’ing the 2700x, which has a far higher power consumption than the 3700X and 3800X.
We recommend picking motherboards largely based on their VRM quality, and thus we recommend this super-useful VRM Tier List for reference.
Best X470 Motherboard for Ryzen 7 3700X & 3800X (OC)
There are two X470 motherboards that are considered best in class for the X470 chipset, with very impressive VRM quality and stacked full of features. These two motherboards are the ASRock X470 Taichi and ASUS Crosshair VII Hero. The Taichi is approximately $70 cheaper than the Crosshair VII Hero that comes in about $280, so I will be focusing on the ASRock X470 Taichi as my recommended non-X570 motherboard for extreme overclocking the Ryzen 7 3700X and Ryzen 7 3800X.
The ASRock X470 Taichi features a 12 phase VRM (6 phases using doublers) for the VCore and a 4 phase VRM for the SoC. The ASRock offers best-in-class VRM across all manufacturers this X470 motherboard will be capable of extreme overclocking the Ryzen 7 3700X and 3800X, even a Ryzen 9 3950X overclock!
Features on this X470 motherboard include dual M.2 slots with the top one featuring a heat-sink, as well as USB 3.1 Gen 2 connectivity, WiFi and a POST-Code display for overclocking. The X470 Taichi features WiFi (not WiFi 6 found on some X570 motherboards) but is only rated at 433MBps, which is not great for 2019.
It could be argued that the ASRock X470 Taichi is by far the best value, high-end motherboard for overclocking any Ryzen 7 3700X, 3800X, 3900X and 3950X system.
Best mini-ITX motherboard for Ryzen 7 3700X and 3800X SFF Builds –
If you’re after a mini-ITX (mITX) motherboard supporting the new Ryzen 7 3700X/3800X, which is capable of extreme overclocking despite its small form factor – then you’re in luck. The MSI B450I Gaming Plus AC is regarded as the best B450 ITX motherboard with a fantastic VRM, decent BIOS and great features – even including a DisplayPort that some ITX B450 motherboards lack. Although only have a single PCIe 3.0 slot, and 2 DIMM slots, this motherboard makes up with WiFi built in, GigE, 4 SATA and M.2. connectivity.
For overclocking the 3700X in an ITX system, one of the drawbacks of the B450I Gaming Plus AC is that it doesn’t have voltage offset, which makes it not ideal for XFR2 and temperature management. With that said, the VRM on this ITX motherboard outweighs any drawbacks, and is why it is our recommendation as the best ITX motherboard for the Ryzen 7 3700X and Ryzen 7 3800X SFF builds. This ITX motherboard will be more than capable of overclocking the Ryzen 7 3700X & 3800X, despite the small ITX form factor.
Best X570 Motherboard for Ryzen 7 3700 & 3800X?
Right now, with no official breakdowns and reviews of the upcoming X570 chipset motherboards, where we can really look into their VRM quality and benchmarks – it is really hard to say which X570 motherboard will be best for the Ryzen 7 3700X & 3800X. In our general best X570 motherboard guide, we have predicted the AORUS X570 Xtreme to be one of the best X570 motherboards thanks to its true 14 phase VRM, with 70A powerstages – surpassing any of the other flagship X570 motherboards.
In addition, we think on paper the ASRock X570 Phantom Gaming ITX TB3 will be the best mini ITX X570 motherboard for the Ryzen 7 3700X and 3800X because of its impressive feature set – with Thunderbolt 3 onboard, optical sound output and 6+2 phase VRM. We will have to wait and see how the three ITX X570 motherboards perform in benchmarks and reviews to see which one truly is the best ITX motherboard for the Ryzen 7 3700X & 3800X.
