Can Motherboards Bottleneck?


When you build a PC, your goal should always be to make a balanced build in terms of performance to avoid bottlenecks. So you usually don’t see an overkill GPU paired with a weak CPU. As with motherboards, certain chipsets can be seen as providing more value to the user, and generally being more overkill. But does this cause a bottleneck?

The main reason why you want to avoid a bottleneck is that it’s a huge waste of a performance. Imagine you spend a lot of money on a powerful graphics card for it to be utilized 50% of the time. This is the importance of building a balanced build, you will want to get the most out of your build.

Answer: Luckily with motherboards, they usually don’t bottleneck hardware. This is because they’re just used to provide a way of communication for the hardware. There are certain chipsets that are seen as being more overkill, or pretty lackluster, but this doesn’t cause a bottleneck. So don’t worry about it too much and focus on getting a motherboard that meets your needs.

What Is A Bottleneck And Why Should You Avoid It?

A computer or a hardware bottleneck occurs when your device is unable to utilize the full potential of its hardware components due to a lack of resources provided by another component. This means that you may experience sluggish performance or poor application responsiveness, depending on which bottleneck is affecting your system.

There are several factors that can cause bottlenecks, including memory limitations, CPU processing power, and bandwidth restrictions. To avoid this issue and ensure optimal performance, it is important to choose your hardware carefully and build a balanced system.

For example, you might want to opt for a high-end graphics card and pair it with a powerful CPU. And remember that bottlenecking can happen at any level from individual parts like memory modules all the way up to your entire PC setup as a whole.

An example of a bottleneck – Paring an RTX 3090 TI with an Intel Pentium processor will usually impose a huge bottleneck due to the differences in processing power. In games, the Pentium processor won’t be able to handle the number of frames being produced by the RTX 3090 TI. To reduce this bottleneck, you can balance the build by going for a slightly weaker GPU and buying a more powerful CPU.

Why Should You Avoid A Bottleneck – A GPU example of a bottleneck, in gaming, the goal is to achieve 100% GPU utilization, this is a sign that your GPU is being used to its maximum potential. So, when you have a CPU holding it back, you will experience significantly fewer frames per second than you should. So, you’ve essentially wasted money as you’re not using the full potential of your GPU.

Why Motherboards Usually Don’t Bottleneck Hardware?

Motherboards don’t cause bottlenecks because they’re not a processing devices. Devices that process information is – CPU, GPUs, and RAM, and these devices can impose bottlenecks. The motherboard is primarily there to act as the backbone for the PC allowing all the computer components to communicate with each other.

In terms of upgradability, a motherboard can limit the potential you have for future upgrades. For example, if you don’t have enough PCI-e slots, then you may not be able to upgrade to a multiple GPU setup in the future. But this isn’t a bottleneck, it’s just a limit on what you can do with your system in the future. Usually, larger motherboards allow for better PCI-E slots.

So, the motherboard is more of a device that can impose physical limitations rather than performance limitations. If you’re aware of the motherboard sizes and form factors such as – mini-ITX, Micro ATX, and full ATX – you should be aware that the larger the form factor, the more upgradability they have.

Influences The Motherboard Has On The CPU

Yes, the motherboard does influence the CPU in some way, usually to do with power delivery. When it comes to VRM(Voltage Regulator Module), it is responsible for delivering power to the CPU. So, in terms of VRM quality, the better it is, the more stable and efficient the CPU can operate.

However, this is usually not a major concern since VRM quality generally only comes into play when you’re overclocking. If you’re doing standard gaming or working on basic tasks then VRM won’t usually matter. So, if you’re going to be overclocking, focus on the VRM as more power phases = more stable overclocks.

This has an impact on overclocking as it means you’ll be able to overclock higher than normal, but only if your VRM is able to support your CPU’s max TDP (Thermal Design Power). If not, then the VRM will become a bottleneck in terms of performance.

The Importance Of Balanced Builds

The importance of a balanced build ties into getting the right amount of performance for the money you’re spending. When you purchase certain hardware, there is a certain expectation you have from them. For example, if you purchase an RTX 3080, you may expect a certain number of FPS in the game.

Luckily, your motherboard doesn’t have a huge impact on the performance of your build. Depending on the chipset, you may have more or less useful features such as M.2 slots, Wi-Fi support, Overclocking, or USB ports. But in terms of pure performance, the motherboard won’t make a difference.

To build a balanced PC, there are helpful sites that are able to calculate whether a specific component can bottleneck your PC. Also, you can reference your PC build to other builds on youtube to see if the performance matches theirs. If it doesn’t then there’s likely some sort of performance limitation.

How To Choose The Right Motherboard For Your Needs

Choosing the right motherboard can be difficult, there are so many things to consider such as the form factor, chipset, socket type, and price. The first step is to decide what you need from the motherboard. If you need a specific feature such as Wi-Fi, then you should prioritize in finding a motherboard that can support that.

Features Depend On The Chipset – Motherboard features usually depend on the chipset you’re using. So, if you want overclocking support, then you will likely need to go with a chipset that supports it. Similarly, if you’re planning on building a PC for gaming, then choosing the chipset that can support features such as overclocking usually results in increased performance.

Form Factor Influences Upgradability – Your form factor has a huge impact on the upgradability of the PC. If you’re planning on building a gaming PC, then a larger form factor such as micro ATX or full ATX will offer more upgradability. But if you’re looking for something that’s compact and portable, then consider going with a mini ITX form factor. Just note that smaller form factors usually come with fewer PCI-E slots and DIMM slots, so you will have fewer options when it comes to memory and expansion cards.


In conclusion, the motherboard usually doesn’t bottleneck hardware, your goal when buying the motherboard is to make sure it has the features you’re looking for, and the correct requirements to support your hardware.

Motherboards impose physical limitations, not performance imitations, so if you want more performance and upgradability, going with a larger motherboard will offer you those things.
