Buying a B450 Board Instead of a B550 Motherboard

AMD finally released its new B550 chipset alongside a wide selection of B550-based motherboards. We’ve waited for the B550 chipset for quite some time and now that it’s here, it’s clear the new chipset brings a plethora of improvements and new features over the B450.

First of all, PCIe 4.0 support is now present both in the flagship (X570) and mainstream (B550) chipsets. This could be a great way to future proof your motherboard and get ready for the new generation of graphics cards. But since tests show that even the RTX 2080 Ti isn’t capable of completely saturating the, now pretty old, PCIe 3.0 x16 slot chances are even the upcoming RTX 3000 and Big Navi GPUs won’t be able to overwhelm the PCIe 3.0 x16 connection.

This means that you should be fine with a PCIe 3.0 motherboard in the foreseeable future. Because, if even the flagship next-gen GPUs won’t use PCIe 3.0 x16 bandwidth to its fullest mid-range cards will be even farther from doing that. Then you have the PCIe 4.0 support for SSDs. This means faster transfer speeds, which may become important after next-gen consoles come out. But, there’s a catch here also. Since both the PlayStation 5 and the Xbox Series X use custom hardware to achieve their insane SSD performance you won’t be able to have the same experience on the PC. At least for now.

That level of SSD performance requires either a custom memory controller used for the SSD (found on a motherboard or a directly on an SSD) or about eight Ryzen cores. The first solution is probably years away while the second requires you to have at least the Ryzen 9 3950X. So yeah, chances are PCs won’t be able to utilize super-fast PCIe 4.0 SSDs to their fullest until they solve this issue. In the end, the PCIe 4.0 support is neat but not required for next-gen GPUs. And when it comes to SSDs, there are still hardware issues to solve before PCs will be able to enjoy the same level of performance as next-gen consoles.

The biggest improvement, aside from the PCIe 4.0, found on B550 boards are much better VRMs. Even the budget B550 boards have VRMs good enough to run literally any Ryzen CPU, which couldn’t be said about B450 boards. But, they are also more expensive, with budget B550 boards costing the same as the best B450 models. Another interesting update is that now, most B550 boards have two M.2 ports instead of one. This can be interesting, now that NVMe disks have lower prices than ever before.

Overall, while the B550 chipset brings lots of upgrades, buying a B450 board in 2020 is still reasonable. If you don’t need PCIe 4.0 support, are fine with one M.2 slot, and don’t plan on getting a 3900X or 3950X processor you’ll be fine with a quality B450 board. They are still a solid purchase, but with a (another) catch. Many B450 motherboards have seen their prices skyrocketing in recent months. Probably because of the arrival of the B550 chipset and because B450 boards aren’t manufactured anymore. And there’s also the global pandemic thingy, which affected production and distribution lines across the globe.

So, it’s fine to get a B450 board, but only if you find one at its regular price. Avoid getting a B450 board at inflated price points because they aren’t worth it. If you cannot find the B450 board you’re looking for then it’s better getting a B550 board, which are available at their regular price points. Now that we got that covered, let’s focus on the best B450 motherboards.
