AMD X670E VS B650E – What are the Key Differences?


With the underwhelming release of AMD’s Ryzen 7000 CPUs, we’ve slowly seen the market become saturated with a range of options when it comes to motherboards. The release of the B650E and B650 chipsets came shortly after the flagship CPUs, providing an alternative option for consumers looking to gain entry to the platform.

However, many were left wondering what this new ‘E’ designated chipset has to offer. AMD have never designed an ‘extreme’ chipset before, so many questions have arisen concerning the available features and pricing of these new motherboards. In this article, we’re going to be answering some of those questions, addressing the differences between the flagship X670E chipset, and the more budget, but feature rich B650E option.

The Importance of Motherboard Chipsets

It is important to note that a motherboard and a chipset are not the same thing. Although they work in combination with each other, there are key differences between them. Your chipset is both a data communication centre and traffic controller, while doubling as the determinant for the features you’ll have access to on your motherboard. Many of these features can be deal-breakers for new builders and enthusiasts alike when picking out a motherboard, such as: PCI-E lanes and slots, CPU overclocking, the rear IO makeup and more.

AMD has retained the same pattern with chipsets since the start of their AM4 platform, and this has remained the same for AM5, even if the names have changed a little. Since the first generation Ryzen chips landed back in 2017, the top-end chipset has always been ‘X#70’. Motherboards which utilise this chipset take a no compromises approach to features, whereby you’re likely to have all of the available features that come with that generation of CPU.

For ‘B#50’ CPUs, the design philosophy is slightly different. These motherboards tend to sit within the budget and mid-range market, offering consumers plenty of features but reducing the amount to save on cost. B#50 boards are generally more affordable than X#70 boards, but both of the chipsets we’re discussing today don’t quite follow the traditional curve AMD has set out with previous generations. Both the B650E and X670E chipsets are the extreme versions, providing more features with widespread PCI-E 5.0, along with better overclocking support too. And because of this, there is definitely a boost in price to be expected.

Major Differences

Before we jump into the differences, it is first worth discussing the technical information concerning the specs and features of the new motherboards. All of AMD’s chipsets are now available on the market, and consumers have a plethora of options available to them for the new platform. In this section we’ll be delving into the various features that come with the new boards, and the major differences between them.

CPU Overclocking Support

When it comes to overclocking, we already know that both of the ‘E’ variant chipsets are designed to be better suited for boosting the new Ryzen 7000 CPUs past stock speeds. Both the X670E and B650E motherboards thus, will have more VRM power phases compared to the other available chipsets. This will invoke a bit of a premium on the boards, but arguably, for the increase in performance it might be worthwhile for many consumers.

ASUS Prime X670E CPU Socket

With X670E motherboards, we can take a look at some of the latest ASUS boards that featured at Gamescom this year. For example, the ROG Crosshair X670E Extreme features 20 + 2 power stages. This is effectively unheard of for mainstream motherboards, and goes to show that X670E boards are designed for top-end overclocking.

Looking at a B650E motherboard as a point of comparison, the ROG STRIX B650E-E has an 18+2 power phase design. Although this isn’t quite as close to the aforementioned ROG Crosshair board. This is more than enough for a steady overclock on a mid-range possibly even top-end Ryzen 7000 CPU. Consumers will have to keep in mind that power phases aren’t everything, but these new B650E boards are more geared towards overclocking compared to the ‘non-E’ chipsets.

PCI-E 5.0, Graphics Cards & SSDs

When it comes both GPUs and SSDs, AMD’s latest platform is likely to be the go-to choice for many consumers. For X670E motherboards, we’re looking at widespread PCI-E 5.0 support for multiple of the latest graphics cards and SSDs. Although we can’t see many users opting for dual GPUs nowadays, this still remains a theoretical possibility.

Gigabyte X670E AORUS Master M.2 Latches

On the other side of the coin for B650E, we’re looking at multiple options for PCI-E 5.0, but less overall. Despite these boards being heavy hitters when it comes to overclocking and other features, they’re still geared towards a demographic that wants high performance at a lower cost. For that reason, B650E boards are cheaper, but when it comes to PCI-E 5.0, this chipset has a similar amount to X670E options with a slight decrease in the total quantity.

Memory Overclocking

With memory overclocking, AMD announced that all of the chipsets will support their new EXPO memory technology. This one-click overclocking method improves performance at 1080P settings, along with making DDR5 memory latency better. Arguably this is needed for DDR5 DIMMs, as the latency is currently one of the only areas holding back a significant performance boost.

As for manual overclocking, this will also be supported, and can be tweaked in the various BIOS settings available with each board partner. This won’t differ much between each chipset, but it may be that X670E supports a higher memory clock speed on average for better overclocking.

Rear & Front IO

Finally is the rear and front IO. The amount of IO you have is determined by a number of factors, with chipset being the main one. X670E motherboards are designed to spare nothing when it comes to features and will have more bandwidth. As such, we can imagine seeing a large amount of high speed IO, including multiple USB4 ports, WiFi 6E, and even 10 Gigabit LAN included here.

Although B650E is definitely an uncompromising chipset, rear and front IO will be reduced to save cost. This means consumers may see one USB4 port instead of multiple, along with less USB 3.2 ports, slower LAN ports, and an earlier generation of WiFi. Connectivity is still strong on these boards, but will need to be confined within the more affordable price tag that comes with the cheaper chipset.

Pricing Expectations & Comparison

In terms of pricing X670E and B650E motherboards are definitely going to be priced higher than the alternative chipsets due to the nature of their design. First off, X670E boards are somewhat expensive. This is a given, considering that these boards are the flagship, ‘no compromise’ designs, optimised to overclock the new CPUs to the max. Admittedly, $400 as a starting price is definitely a lot, but this is what was seen by consumers during the initial launch of these boards. B650E motherboards will be significantly cheaper, these motherboards are likely to cost around half as much, starting at the $300 or so mark.

If you’re saddened by the cost of these boards, we’d recommend taking a look at the more budget oriented B650 boards. This chipset has less features compared to the three other available chipsets, but you’ll be paying less overall to secure one.

Overall Differences Breakdown

With the release of any new range of CPUs, the amount of features available to consumers takes a step forward. With Ryzen 7000, that step looks to be a very significant one.

In relation to PCI-E lanes, both of these chipsets will offer the most, when compared to their X670 and B650 counterparts. Having more PCI-E lanes means both of these chipsets can support more graphics cards and SSDs. For X670E, we’re looking at widespread compatibility, with this chipset offering the most in terms of PCI-E 5.0 ready slots, for both SSDs and graphics cards. Following second will of course be the B650E chipset, offering consumers slightly less PCI-E 5.0 compatible slots and lanes, but providing consumers the option to utilise two or more components with this higher bandwidth generation.

X670E will utilise the highest amount of USB ports, with the most room for USB4 ports, and USB 3.2 Gen2x2. B650E motherboards have a similar amount of rear and front IO, but this is a feature determined by the manufacturer and the price of the board. We’ve mooted 12 as the max number of USB ports for B650E, but this could be more or less dependent on manufacturer’s own decisions.

In this versus article, we’ve taken a look at both of the ‘extreme’ chipsets on the AM5 platform, and compared them to find out any differences and similarities. The X670E chipset is the flagship offering from AMD geared towards the top-end side of the market. There are mid-range options for consumers looking to spend a little bit less, but this chipset is predominantly expensive. But arguably, you get what you pay for. These boards offer a huge amount of features that come with the new platform, such as USB4, widespread PCI-E 5.0, and high VRM power phases. With all motherboards, the caveat to getting more features is unfortunately price.

The B650E chipset on the other-hand is a slightly cheaper alternative to the X670E option, whilst still providing a vast feature set. These boards do have a reduced amount of features comparatively, due to less PCI-E lanes. But, consumers still get access to Gen5 slots, high VRM power phase count, and options like USB4 dependent on the price.

I’d say, if you’re looking to spend some money to secure a board that you won’t need to upgrade for the length of the platform’s life span, the X670E boards might be a better offering. But for those looking to spend a little bit less money but still secure an excellent board with a plethora of features, the B650E chipset is a better option.
