B550 vs B450 vs X570 – Which to buy?
|Are you stuck wondering if you should buy a B550 motherboard, or go B450 instead, or even X570? It’s a little confusing, so in this video I want to explain the pros and cons of each, and help you understand which is for you. But first, if you haven’t already, consider subscribing for more videos every Monday, Wednesday and Friday!
Since B550 is the new kid on the block, lets start with that. B550 is AMD’s latest chipset, it offers limited PCIe Gen 4 support, in theory PCIe Bifurcation, and most boards I’ve seen have rather beefy VRM setups. It also costs not too far off double it’s B450 counterparts. And finally, it’s “guaranteed” to get simple BIOS updates to support any “Zen 3” based Ryzen CPUs, although doesn’t officially support anything other than 3rd gen Ryzen CPUs.
B450 on the other hand, doesn’t support PCIe Gen 4, has hit or miss VRM setups, and only some boards may get irreversible BIOS updates to support “Zen 3” chips, while dropping support for anything other than those CPUs. It does however, support any Ryzen chip you want to put in it at the moment, and these boards tend to be significantly cheaper than a B550 version of the same board.
X570 is a bit of a wildcard here. It’s technically the most premium, and most advanced chipset, offering full PCIe Gen 4 support, actual Bifurcation, and mostly solid VRM options, although depending on the board is still generally more expensive than B550. These will see updates for “Zen 3” chips, and currently have limited support for Ryzen APUs, including the 3200G and 3400G chips, but do support 2nd Gen Ryzen chips out of the box.
So what does all that mean? If you are on a budget and want the best value for money right now, you likely don’t care about PCIe Gen 4 (you shouldn’t really anyway), or bifurcation, so unless “worry free” Zen 3 upgrades are a very strong issue with you, B450 is where you should head. If you can find one, the MSI B450 Tomahawk Max is the best regarded board around, ASRock’s Steel Legend is great from my experience too.
If you do want PCIe Gen 4 and easy upgradability, and you’ve got a bit more money to spend, I think it might actually be worth spending a few quid more and getting X570, as you’ll get a better board with full gen 4 support – although there are some caveats there. Say you were looking at the MSI B550 Gaming Edge WiFi, that’s listed for £195 on OverclockersUK, but it’s X570 counterpart is only £5 more. But, almost all B550 boards are coming with WiFi 6 and 2.5Gb Ethernet, so if you can make use of that more than full PCIe Gen 4 support you’d be better off with B550.
I’m hoping pricing for B550 boards comes down a little to make them a more reasonable proposition, especially compared to X570 boards as right now it’s a little hard to both justify, and differentiate.
So to recap, if you want the best value, B450 is still where it’s at. If you want Gen 4 support and better WiFi/Lan, B550 is for you, and if you want the best of the best, or a truly high end option (which might have 10GbE, for example), X570 is for you.
