B450 vs x570

Maybe you've followed the latest version of the AMD motherboard, but you're not sure how they compare. Located in the high and mid-range of the new version of the AM4 chipset, looking at X570 and B450 is a good way to understand which motherboards are worth your while.

Like GPUs, different brands may provide additional features for these motherboards, so we try to keep our information on a technical basis. This means that whether you buy a motherboard from MSI, Gigabyte, or ASUS, you know what will happen.

chipset Let's start with some basics, namely appearance. The main form factor you want to know is the physical size of the circuit board, because you want it to really fit your case, and how many mounting points the circuit board has, because you will use these mounting points to fix it.

Starting from the size, the B450 motherboard is built in the standard ATX style. You can expect from many modern motherboards based on Intel's typical circuit board design. This means that the size of the dashboard is 12 inches x 9.6 inches, or specifically 304.80 x 243.84 mm. The same is true for X570, because it also uses an ATX form factor.

So what does this mean for the brackets on these motherboards? They are all installed with four screws located on the back of the circuit board. Thanks to the AM4 socket, the horizontal length of each hole on these new motherboards is 54 x 90mm. Both

motherboards are AMD models, but after mentioning Intel and its standardized ATX motherboard design, these competing parts makers are worth talking about.

Although most motherboard manufacturers use Intel's ATX design for their circuit boards, these AMD motherboards use AMD's own chipset, which is different from Intel's Pentium and LGA chipsets.

It is impossible to compare the entire contents of each company's chipset catalog in a few sentences, but what we can say is that the motherboard you are using is designed to work with all the other devices in your computer. Just like Nvidia optimizes its GPUs and motherboards to be compatible with Intel motherboards and CPUs respectively, if you have AMD CPUs, GPUs, or both then you'd better choose AMD motherboards over any other brand. The type of socket used by the

motherboard determines the number of pins on the motherboard and their configuration, which will affect the operation and heat dissipation capacity of the motherboard, which in turn affects your computer. Both the

B450 and X570 motherboards use the Socket AM4 microprocessor socket, which is their latest socket innovation and designed to be compatible with AMD's Zen 2, Zen 3 and Excavator microarchitectures. All of this means that it is a fairly robust socket that is future proof when released, like many elements of the Zen 2 architecture.

Socket AM4 uses a 1331-pin socket and can support DDR4 memory, which was lacking in previous versions. from AMD. The

AM4 presents potential hurdles in terms of radiator compatibility, but the side length of the radiator attachment hole has changed from 48 x 96mm to 54 x 90mm.

This change makes some heatsinks incompatible with the motherboard, so if you want to use a heatsink, you need to check if it comes with a usable AM4 compliant bracket. You may be able to find mounting hole motherboards for AM3 and AM4 configurations to help you solve this problem. Along with the physical socket microprocessors used by AMD, the

must consider the virtual chipset that comes with them. The name of the motherboard here is its chipset, so the B450's chipset is B450, and the same goes for the X570 board. So far, these motherboards are very similar, but their biggest difference lies in the chipset.

B450 belongs to AMD’s 400 series, and X570 belongs to 500 series, so you should be able to find out which is a technologically advanced motherboard. The AMD B450 chipset is an excellent mid-range motherboard from AMD’s latest motherboard products. It is very suitable for users who want to have a motherboard that can handle overclocking without supporting multiple GPUs. On the other hand,

X570 is AMD's most advanced overclocking platform. Because of its world's first PCIe 4.0 support, which we will introduce later, it can support dual graphics card configurations. This makes X570 clearly the best choice for gamers looking for performance or passionate graphics. The big difference between these

chipsets is their compatibility, which actually favors the B450. This is because B450 is compatible with Athlon and Ryzen series CPUs from 1000 to 3000, or even 5000, depending on the BIOS update. This means it can work well with your old parts. X570 is only compatible with Ryzen 2000 to 5000 series

. Now we have covered some of the most important factors to consider, and there are other functions we can cover. Check out the small section below to learn more about the B450 and X570 and how they compare.

desktop boards usually do not have built-in Wi-Fi. When they are built-in, it is usually due to a specific brand variant of the motherboard, rather than AMD’s embedding of Wi-Fi into the actual on-board chipset.

For this reason, many commercial versions of B450 motherboards do not have built-in Wi-Fi capabilities. We have seen the exception

You need to install, there are also two PCIe 4.0 x1 slots. The

B450 has a PCIe 3.0 x4 port, a 3.0 x16 port for graphics cards, then a 2.0 x16, and two 2.0 x1 slots. An M.2 slot is paired with a 3.0 x4 port to increase throughput speed, and six SATA III ports can be used for storage. The

memory speed is where we see the X570 beat the B450. This is because, although they all have four memory slots, the maximum capacity of the B450 is 64 GB of DDR4 RAM and the overclocking frequency is 3466 MHz.

However, the four memory slots of the X570 have functions of Dual channel DDR4 RAM, so the maximum can reach 128GB. When overclocked, their memory speed reached 4400 MHz.

You want to ensure that the memory capacity and speed are as close to the CPU as possible, so that you don’t have to wait for a response while the processor is working.

Also consider the pre-installed BIOS on the motherboard and the CMOS that contains it. If this is not your first computer, then you may know that the BIOS is the interface you see when you first boot, and you can access it during the boot process by pressing the indicated F key.

Although not every motherboard comes with it, some retailers will sell motherboards with clear CMOS buttons for BIOS flash memory. When critical BIOS software updates occur, you can’t just download them to a drive on your computer. The BIOS is stored on the CMOS chip and is accessed and updated through flash memory. The

button makes this process more convenient because you can use the USB with the necessary files and a button to update the BIOS without having to install new motherboard components. Since both boards can have these buttons, and their CMOS chips are functionally the same, there is no real point of comparison here.

Looking at the b450 and x570 motherboards it is clear that they are very similar, for example they share manufacturer and form factor. It seems like the only obvious difference between them is the slot and chipset specs. As a rear motherboard model, the x570 wins out.

This does not mean that x570 is the best fit for your needs. Although facing the future, the x570 abandoned the old AMD hardware compatibility in preparation for updated models, which may mean that if you can’t or don’t want to upgrade other parts of your desktop, then b450 will be the best choice.

If you want to buy a motherboard for a newly built PC, you can buy the x570 at a slightly higher price than the b450. However, if you want to upgrade the motherboard, we recommend that you take stock of other components you are using and make sure that they are compatible with x570.
