Best MotherboardsBest X670 MotherboardsBEST B650 Motherboards [Expert Recommendations 2024]

Recently, AMD announced and launched its new AM5 architecture, the Ryzen 7000 series processors. In addition to architectural improvements, the AM5 socket has shifted from PGA (Pin Grid Array) to LGA (Land Grid Array). Today, we will focus on X670 Vs B650 motherboards that support these processors.

X670 Vs B650 Motherboards

Looking at both motherboard chipsets, we realize they follow the older X570 Vs B550 motherboard mindset. While the X670 is the better chipset, the B650 likely offers better pricing. Meanwhile, we expect the X670 to bid a few extra features than its competitor. For that reason, let’s take a closer look at what users get with both motherboard chipsets.

PCIe 5.0 For GPUs And SSDs


Firstly, you can find an x16 or x4 PCIe 5.0 slot in a cheaper X670 motherboard. Additionally, with AM5, we see a total of 28 lanes instead of the previous 24. So, that’s an increase of 4 lanes off the bat, providing for more efficiency. Couple the extra lanes with the PCIe 5.0 speeds of 4.0Gb/s/lane, and we notice faster speeds.

For example, the Gigabyte Aorus X670 offers 1* PCIe 5.0 x4 M.2 and 3* PCIe 4.0 M.2 ports. Then again, the Aorus Elite X670 motherboard is one of the cheaper X670 chipset options.


On the other hand, if we look at a B650 motherboard, higher-end B650s are likely to have PCIe 5.0 lanes. Otherwise, entry-level B650 motherboards will likely not house any PCIe 5.0 lanes.

For instance, if we look at the MSI B650-P motherboard, we don’t get to see any PCIe 5.0 lanes. Mainly that’s because PCIe 5.0 lanes are a feature for B650E motherboards. However, the MSI B650-P does have 28 PCIe Gen 4.0 lanes, which should be plenty for massive data transfers.

Overclocking Capabilities

The X670 motherboards have better overclocking capabilities. A motherboard with thicker VRMs and more MOSFETs would probably overclock better. Because the X670 chipset is more expensive, we expect them to have better-quality VRMs. Therefore, hardcore users usually go for this.

The B650 chipset is a curve ball for consumers. Entry-level B650 chipsets are great for their price but barely match entry-level X670 motherboards. In conclusion, while the X670 chipset overclocks better, depending on the B650 motherboard you buy, you might get better results.

USB Ports

The X670 motherboards have more USB 4.0 and USB 3.2 ports than the B650 motherboards. . These differences exist as a form of cost-cutting for the more affordable B650 motherboards. However, the more expensive B650 motherboards will likely have USB 4.0 ports and fast LAN connections.

For example, the MSI B650 PRO, costing $220, offers 2x USB 4.0 ports and a 2.5 Gigabit LAN connection. In comparison, even affordable X670 motherboards, such as the Aorus Elite X670, offer USB 4.0 ports. But it’s important to note that faster USB ports are useless if your peripherals don’t support the technology.


Looking at entry-level X670 motherboards, the cheapest X670 motherboards cost around ~$250-$350. Meanwhile, the higher-end X670 motherboards in the X670E chipset cost over $1000. Of course, with the X670E chipset, consumers gain many features and amazing overclocking support.

Secondly,  the cheapest B650 motherboard, the MSI B650 PRO, costs ~$220. Also, a cheaper variant, the MSI B650M-A, costs ~$190. However, that particular variant is for mATX cases. Furthermore, looking at the more expensive B650 motherboards, we have the MSI MPG B650 Carbon WiFi at ~$330. 

Should You Buy X670 Or B650 

B650: In summary, while B650 motherboards might have better pricing in the lower-end range, the story changes in the higher-end market. So, make sure you only go for it if you are getting a good deal on it.

X670: If you’re planning to buy a high-end B650 motherboard, you might be better off buying an entry-level X670 variant. Not only will you get all of the features of the B650 variant, but you will save some money, too.

Overall, if we look at the prices, both chipsets are extremely costly, even costlier than the processors they support. Therefore, AMD plans to release a B650 chipset later to save on costs. However, you can potentially forget those motherboards’ PCIe Gen 5.0 and USB 4.0 ports.

We recommend that you check out our Gigabyte Aorus B650 review if you wish to go with that chipset, while the X670 enjoyers can take a peek at our Gigabyte Aorus X670e review!


What is the main difference between the X570 and X670 motherboards?

The main difference lies in their CPU socket, with X570 using the AM4 socket and X670 utilizing the newer AM5 socket.

Can I use a Ryzen 7 CPU on X570 and X670 motherboards?

Yes, both motherboards support Ryzen 7 CPUs. However, the X670 motherboard with its AM5 socket also supports higher-end Ryzen 9 CPUs.

Which motherboard is better for future-proofing and overclocking?

The X670 motherboard provides better future-proofing and overclocking capabilities due to its upgraded VRM power phases and support for PCIe 5.0.
