Chipsets & Motherboards

One of the most important questions that we get asked is ‘what are the differences between chipsets and motherboards’? Many consumers tend to muddle up the definition of a chipset or motherboard because they both work together, while being distinctly (and confusingly) very different. A motherboard is the physical PCB that all of your components and power connectors will slot into. Whereas, a chipset is both a traffic controller, and the determiner for the kind of features you should expect on your motherboard.

As a general rule, AMD have always kept three different chipsets with every major CPU release. These are: ‘X#70’, ‘B#50’, and ‘A#20’. For Ryzen 7000, the A#20 chipset has been dropped as far as we know, but recent rumours do suggest the potential return of an A620 chipset as a budget offering. However, both the new X670 and B650 chipsets are a mainstay that have moved onto the next generation of CPUs.

The previous X570 chipset was generally at the top of the line, offering the most amount of features available with Ryzen 5000 CPUs. However, based on the fact that we’ve gotten a new X670E chipset it is unlikely AMD have followed suit. For the ‘B’ range of chipsets, these were designed to offer a more budget oriented approach while still providing consumers with great performance and plenty of features. The B650 chipset has followed in the footsteps that AMD outlined previously, but instead with DDR5 compatibility.

X670 & B650 Major Differences

In this section we’ll be jumping into the major technical differences between the X670 and B650 chipsets. The new motherboards have primarily saturated within the market, so consumers have access to a plethora of options at varying price points. These chipsets are rather different, and we’ll be delving into the contrasts below:

Overclocking Support

First off is overclocking support. AMD have told us that overclocking won’t be limited to any specific chipset, which is good for both enthusiasts and first-time builders. However, the amount of VRM power phases you have, along with cooling and CPU capability will be different between chipsets and motherboards.

ASUS Motherboards CPU Still

Both X670 and B650 motherboards do support overclocking, but the state of how far you can push your CPUs will be determined by the power phases and quality of the board. As a general rule, both of these chipsets are not necessarily designed for overclocking, and thus, they will have weaker power delivery. As an example, MSI‘s X670-P motherboard has a 14+2+1 power design making it great for overclocking CPUs in the mid-range market with potential room for higher-end Ryzen 7000 CPUs too.

PCI-E 5.0 – GPUs & SSDs

For both X670 and B650 motherboards we’ve seen a mixture of PCI-E Gen5 and Gen4. The less expensive motherboards on the X670 chipset only feature one element of PCI-E 5.0 in the form of an x16 or x4 slot. B650 boards follow a similar situation, whereby Gen5 support is the same. But PCI-E lanes have decreased for Gen4 and Gen3 on this lower-end chipset. This is ultimately to keep down costs for this budget chipset.

ASUS Motherboards PCI-E Still

As we can see on the MSI X670-P WiFi, you’ve got access to two PCI-E Gen4 slots on the GPU front. And in terms of storage you’ve got one Gen 5 M.2 slot, and three other Gen 4 slots. This is a massive amount of speedy storage slots, and other top-end X670 motherboards will offer a lot more. B650 boards have received a similar treatment, but there are less available features comparatively.

Memory Overclocking Support

During AMD’s Ryzen 7000 press conference we received some news about their new EXPO memory technology. This new technology allows consumers to use a ‘one-click’ overclocking profile which enhances the clock speed and decreases the latency for a performance boost.

AMD Expo Overclocking Technology

All of AMD’s new chipsets are going to have access to this technology, and over 15 kits will be available on launch with this new memory profile, improving DDR5 memory. DDR5 does at the moment suffer from poor latency while having an extremely high clock speed. So being able to enhance your PC’s performance on any of the chipsets with a simple setting is very consumer friendly!

Rear and Front IO

The amount of available IO tends to differ quite significantly between chipsets due to both costs and power requirements. As a general rule, the top-end boards will house the most amount of IO. On X670 boards this means we might get access to some USB 4 Ports, along with some other high speed USB 3.2 ports, and high speed networking options.

ASUS TUF Gaming Motherboard Rear IO Still

B650 boards have suffered on this front to some extent due to the budget-oriented nature of the chipset.. Although consumers can expect plenty of USB 3.2 ports, high speed networking and USB4 is entirely dependent on the manufacturer’s discretion. Some of these more high-end features do appear on more expensive B650 motherboards, but with B650 boards sitting in a budget bracket, these IO options are somewhat more scarce to keep costs down.

Our Pricing Expectations & Comparison

X570 and B550 motherboards released at a very reasonable price, but as these motherboards are DDR4 compatible, there is an expectancy for them to have a lower cost on average compared to Ryzen 7000 boards. For B650 we’ve priced these boards slightly higher than their B550 counter parts. Despite being DDR5 compatible, this is only the biggest difference between B650 and B550 boards, with the inclusion of PCI-E 5.0 as well. AMD board partners tend to offer great prices when it comes to budget options, and this has remained mostly the same when it comes to the newest AMD platform.

For X670 boards the lower bound of these options fell around the $300 mark. Although X670 motherboards could be priced lower, it is unlikely the price will be much less due to how feature rich these boards are, and until we get a new generation of chipsets. At the top end of the spectrum we’ve said the price could sit at $600. Again this is just an average price, but these boards will be geared towards enthusiasts that don’t want to pay an extra premium for X670E options.

$300 – $600$200 – $300$200 – $500$150 – $300
Note – This pricing guide is based on a rough estimate of the prices for the X670 and B650 chipsets.

Table of Differences between X670 & B650 Chipsets

Overall Differences Breakdown

The table we’ve created above lists the specifications that we’ve seen from both the X670 and B650 chipsets. First off we can talk about PCI-E lanes, GPUs and SSDs. X670 boards offer a reasonable set of options when it comes to GPU and SSD slots, with consumers getting access to one Gen5 option, with the majority of the board offering Gen4 and Gen3 where needed. B650 motherboards are in a similar situation when it comes to Gen5, whereby the available slots are down to the discretion of the manufacturer.

For IO and other features, B650 boards are somewhat more limited in terms of choices. This means USB4 ports won’t be making much a major appearance here, and there are less high speed USB ports across these motherboards. For overclocking, although the B650 motherboards may have the capability of overclocking, VRM power phases are weaker on this chipset option. By contrast, X670 motherboards will be perfect for overclocking offering more VRM phases and better cooling. IO will also be on similar standing where these boards have more options for high speed USB ports, and other features.
