B450 vs X570 Motherboards Compared – Which Is Better In 2021?

With the release of their newest line of CPUs – AMD Ryzen 3000 – more people are diving into team red to give AMD a chance. However, due to the incompatibility with previous AM3+ motherboard standards, which it has superseded, this doesn’t come without some confusion for those coming from intel or those new to PC gaming.

Sure, choosing between the B450 or X570 sounds intimidating. But these two chipset’s benefits will come in handy for different kind of PCs. For instance, if you need more demanding performance, the B450 is the way to go. But for things like low-cost efficiency, power efficiency….. this where X570 will really shine!

Before Jumping In: Questions To Ask Yourself

With PC components, it’s important to do the proper research and explore your options before jumping in. The situation with their rise in popularity is not cut and dry: one product doesn’t exist that is simply better than any other in every scenario. Instead, think about compromising when possible if cost is an issue.

Before you jump into the world of machine, it’s important to know what you want out of your machine. Here are a few questions from the article that will help get you started:

  • Budget. What is your budget for the entire rig?
  • What sort of games do you intend to play, if any?
  • Do you think you’ll be interested in overclocking?
  • Will you need support for 2 or more Nvidia graphics cards?
  • What non-gaming tasks, if any, will you use your PC for?

There are many things to keep in mind before jumping into building a PC. What are your needs? Do you have the time? Is it compatible with your current system? It’s beneficial to have a build plan of all the components you intend on using, as that plays into budgeting and getting the most out of your machine.

After deciding on the chipset, we can move on to the more in-depth differences between models. For instance, do you need mild overclocking or prefer to keep your options open? What about opting for PCIe Gen 3X4 M.2 slots?

New computers, such as the X570 can do things that an older computer, such as a B450 cannot. If you’re worried about budget constraints, consider a B450 motherboard.

Of course, a machine can’t beat a human competitor yet. You could purchase a machine for as little as £50. However, one has to be careful not to expect a lot from general graphic cards – it can either play general games at low settings or high settings at low framerate.

The new AMD X570 chipsets were released in mid 2019 and usually have more features than B450 motherboards. They are more expensive, usually ranging from £150 to upwards of £260. Their typical clientele includes gamers with dual GPU rigs and enthusiasts who want some overclocking on their build.

B450 vs X570 For Those Of You On A Budget

Choosing a B450 motherboard should be a no brainer. These are an affordable alternative to motherboards on the more expensive side of the AMD spectrum, while still containing many of the necessary features. Particularly if you’re building on a low or medium/low budget ($500).

For gamers on a budget, focusing your money on the CPU and GPU leads to better gaming performance. Generally, the cheapest X570 motherboards are more than twice as expensive as their B450 counterparts.

For instance, the Gigabyte X570 GAMING X motherboard is roughly £80 more expensive than Gigabyte’s Gaming B450 model. If you prioritize gaming performance in your selection process, this £80 difference could be the difference between a decent card like the Radeon RX 5500 and an awesome card like the Radeon RX 5600XT.

B450 vs X570 for When You Are on a Budget

Best Overall For Performance

The more difficult choice for a PC enthusiast is to make a decision depending on their individual needs. First, those that have two Nvidia GPUs should buy an AMD motherboard as B450 doesn’t have SLI support.

If high end overclocking is your custom, then you might want to choose X570 as your motherboard chipset as opposed to B450. While B450 does support overclocking with the weaker end of the Ryzen spectrum of CPUs, it appears that with high-end Ryzen chips, it might fall short compared to other chips.

Ultimately, the high-end X570 class is for those who need best in class performance or want to wait and see with the rumored higher memory speeds

Higher Speed and Latency: While it’s true that memory speeds does make a world of difference, Ryzen might not be able to take full advantage.


Socket type for a motherboard has certain effects on its operations and is important to explore.

Socket AM4 was designed to have compatibility with both upcoming generations of AMD microarchitectures, Zen 2 and Zen 3. This is arguably one potential flaw in the follow-up socket choice.

In anticipation of Opteron, AMD released Socket AM4 that can support DDR4 memory- something that the previous models were lacking. Socket AMD includes 1331 pin slots and is a suitable motherboard for Opteron.

Socket AM4 seems to have potentially created a new barrier with it’s changes to heatsink compatibility, where the lateral length of heat sink fastening holes is now shorter than on earlier sockets. Fortunately, cooling companies like DeepCool are already adapting by creating fittings that give fits for both new and old sockets.

Changes in size with newer motherboards made some heat sinks incompatible, which is an issue for people with older sockets. You can find motherboards that have mounting holes for both AM3 and AM4 configurations to help you get over the issue.


Chipsets are also known as Virtual Chipset. They were created by AMD for their Socket Processors, but later they were used by many processors including Intel with the release of Socket 1156. Considered in conjunction with physical sockets, they introduce a new dimension to motherboard implementation with the need for thorough knowledge on implementation with particular chipsets.

The AMD B450 is an “advanced” chipset, so if you are looking for a mid-range motherboard to support overclocking, this chipset is worth consideration.

The X570 is a pro overclocking platform, and already a pro gamer for enthusiasts for graphics performance.

The only difference between the two chipsets is that the B450 is compatible with Athlon and Ryzen 1000 series to 3000 series CPUs, and maybe 5000 depending on a BIOS update. The X570, however, is only compatible with the AMD 2000 to 5000 series instead.


Desktop motherboards don’t often have Wi-Fi built in to them; if they do, it’s usually because the board is branded or because wi-fi was added to it by AMD (not out of the chipset).

To that end, many commercial variants of the B450 or X570 motherboards on the market, do not typically offer Wi-Fi capability on their board. For example, some do not come with 802.11AC on board. However, exceptions can be found among sub $200 variants of both boards types, for example MSI’s higher priced MSAR X570 motherboard comes equipped with an excellent wireless solution.

PCIe 4.0

The release of PCIe 4.0 has had mixed reviews, with only one motherboard that is supported out of the box. With X570, owners get an additional benefit of two PCIe 4.0 x16 slots for graphical processing units (GPUS) to install in.

The B450 motherboard also contains a PCIe 3.0 x4 port, a 3.0 x16 port for the graphics card, and then a 2.0 x16 and two 2.0 x1 slots for installation. The M.2 slot works with the 3.0 x4 port to increase performance speeds, and six SATA III ports are available for storage disk drive possibilities on the motherboard’s connectors.

Memory Speed

The X570 has outperformed the B450 when it comes to memory speed because, even though they have four memory slots, the B450 maxes out at 64GB of DDR4 RAM and overclocks at 3466 MHz.

The new X570 boards from AMD reach a memory speed of 4400mhz by using dual-channel DDR4 ram and overclocking.

Choosing the best memory type and speed will allow for instant responses from other devices. Wait time can slow your computer from functioning optimally, so it is important to have the best possible setup.

Clear CMOS/Flash BIOS

BIOS pre-installed into motherboards and the CMOS that contains it also need to be considered. If you’ve not sest this computer away before, then you’ll likely know BIOS as the interface you’ll see upon your first boot up, and from there you can access CMOS during the boot process by pressing the indicated key.

Unlike a motherboard, a CMOS chip only stores the BIOS which you can clear using buttons. When upgrades to your operating system come out, you can’t just download them to a drive on your computer, because the BIOS is stored in CMOS. You access and upgrade the CMOS chip by flashing it.

Buttons make this process much more convenient since you can use a USB with the requisite files and a button to flash the BIOS instead of having to install a new motherboard part. You would much rather have your BIOS wiped clean rather than replace the motherboard, so these buttons are an intuitive way to avoid that hassle. Since both boards can have these buttons and their CMOS chips are functionally identical, there’s no real point of comparison here.

Future Proofing Your Build

If you value the longevity of your machine, then future proofing is undeniable. X570 will give your GPU twice as much bandwidth to work with-an advantage which will allow it to handle graphical demands for many years to come.

In the future, you’ll need a motherboard that can keep up with any upgrade to your GPU. The B450 motherboard might not have the capabilities to allow these future upgrades without purchasing a more expensive one or being stuck until new models come out.

Future proofing is not dreaded because rapid technological advancements in the industry are unavoidable. Documenting PC builds has become standard practice–hopefully offering buyers more buying information in the current volatile hardware market.

It may be time to future proof your build. Since many changes in technology happen unanticipated, you may want to think now about what the newer models will need to meet those changing needs. For example, your £300 X570 motherboard might not be as well-prepared as you think for the coming X80 motherboard.

Dont Forget About This..

And secondly, if you’re not vying for top builds but want to save money, then it would seem the only reason why you would use the X570 chip is if your motherboard could afford it.

An SLI setup is not able to be used in this computer and the cooling system is not adequate enough to handle the slight overclocking advantage of X470.

However, the X570 motherboard may be least desirable for some, because

Whether you need a test machine for your M.2 SSDs or plenty of USB connections to make data transfer a breeze, the X570 chipset supports it.

Alternative Options vs B450 & X570

While there are some solid options in B450 and X570 AMD processors, my preference is the Ryzen 7 1700.

  • Waste no time deciding if you need a B450 or an X570. They both cater to the same niche demands but are still vastly different in their features. Yes, one might be more perfect for your needs, but there is always the other to fill the role of backup.
  • There are two new options for enthusiast tier motherboards: the B450 and the X570. The X470 offers a number of similar features to the B450, but is much more expensive than its counterpart because it can house high speed memories and PCI-E 4.0 cards. If you’re looking for a comparable product to consider over the B450, you should research and compare both these products and weigh in your own personal preferences.
  • If you’ve got a budget– and we know we said it takes some money to make a great system–there are ways to save. Used components and tier 1 parts from previous generations can often be found trading hands for affordable prices.

Our Recommendation

If you have a limited budget, the Gigabyte B450M GAMING is a fantastic option. Notably, stretching your budget to an X570 will provide a future-proof build.

The X570 supports multiple PCIe devices such as WiFi and 2 GPUs.
