The rear panel also includes four USB 3.1 ports, two USB 2.0 ports, an HMDI and DisplayPort, and a combination of audio jacks. Finally, the Realtek ALC887 Audio Codec supports 7.1-channel audio. However, this is a low-end solution that isn’t greatest for users who plan on using this board with high-def headphones.
Buying a B450 board instead of a B550 motherboard
AMD has 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. On the other hand tests show that even the RTX 3080 isn’t capable of completely saturating the good old PCIe 3.0 x16 slot.
This means that you should be fine with a PCIe 3.0 motherboard in the foreseeable future. If the flagship GPUs cannot use the PCIe 3.0 x16 bandwidth to their fullest, mid-range cards are even farther from doing that. Then you have the PCIe 4.0 support for SSDs.
This means faster transfer speeds, which can bring faster loading times than with SATA SSD in lots of games, as well as some asset-streaming optimizations, but just in a couple of titles (like the recently released Cyberpunk 2077). If you want to learn more about highs-speed SSD storage and whether you need an ultra-fast SSD check out our guide that asks (and answers) the question of whether is an SSD worth it for PC users.
That said, even the fast NVMe PCIe 3.0 SSDs look like they will be enough for any game coming out in the foreseeable future. In other words, you’ll most likely be fine in case you opt for a B450 motherboard.
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 useful to many users now that NVMe disks sport lower prices than ever.
Finally, while the B550 chipset got the exclusive rights for the Zen 3 CPUs, by now, most B450 boards have received BIOS updates allowing them to run new Ryzen CPUs. Future BIOS updates should also bring support for new OC features, like the Adaptive Undervolting.
Overall, while the B550 chipset brings lots of upgrades, buying a B450 board in 2022 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 the 3900X or the 5900X, you’ll be fine with a quality B450 board. They are still a solid purchase if you can find them at their MSRP.
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 to get a B550 board, which are available at their regular price points.
