Which function a Motherboard’s chipset perform? [2024]

To fully understand the motherboard chipset’s operation, we must first know what is a motherboard chipset. A chipset, which is located on the motherboard, acts similarly for the motherboard as a CPU behaves for the whole system. It regulates data flow and communication between the CPU, RAM, storage, and other peripherals that are connected to the motherboard. In addition, a chipset has a controller and chips inside it, so it defines how many high-speed components or USB devices your finest motherboard may support.  

Intel and AMD are the most famous mobo chipset manufacturers, although they may be found on motherboards made by various third-party suppliers, including MSI, Asus, and ASRock. A chipset is essential when purchasing a computer, so be sure to select one that is good quality. It makes a big difference in performance as the difference between an Athlon XP 1600+ and an Athlon XP 1900+. While the original DDR chipsets for Athlon were faster than their SDRAM ancestors, subsequent generations have consistently outperformed them.

Key Takeaways

  • A chipset is a set of integrated circuits that controls the communication and data flow between the motherboard and other components, such as the CPU, RAM, hard drives, and graphics cards.
  • A chipset consists of two main parts: the northbridge and the southbridge. The northbridge connects the CPU to the RAM and the graphics card, while the southbridge connects the CPU to the other peripherals, such as USB ports, audio ports, and SATA ports.
  • A chipset determines which CPU socket and memory type are compatible with the motherboard, as well as the maximum speed and bandwidth of the data transfer between them.
  • A chipset also affects the overclocking potential and power consumption of the motherboard and its components, as well as the features and functions that are available, such as RAID support, Wi-Fi support, and RGB lighting.
  • A chipset is usually designed by the same manufacturer as the CPU, such as Intel or AMD, and has a specific model name and generation that indicate its performance and compatibility. For example, Intel Z490 is a high-end chipset for 10th generation Intel Core processors.

Which function a Motherboard chipset perform?

As per the definition, a motherboard chipset acts as a dedicated brain for the motherboard, controlling every in and out of a computer. It’s like a second supervisor after the actual CPU, controlling the overall data flow so the performance of all the components that are connected to the motherboard. This is the basic understanding of a motherboard’s chipset. In contrast, for a better chipset’s understanding, we have to dig down into why a computer chipset matters. Let’s explore this in the next section with different factors!

Expansion and chipset lanes

Only a top-tier motherboard chipset can let you enjoy excellent graphics performance, better RAM clock speeds, and other features while playing games and creating content. For your information, there are specific PCIe lanes on the chipset for expansion purposes. The data flow is directly proportional to the number of lanes. The number of these lanes can vary between 8 to 40 while having a two-way data flow between the connected components. If you have ever seen x8 or x16 configuration for a motherboard chipset, these are what we’re talking about. 


Another factor that is directly related to the motherboard’s chipset is the overall connectivity, utility, and compatibility of the motherboard with the other components. The motherboard’s chipset directly supervises the selection of various elements like graphics cards, processors, RAM, and others. Suppose your motherboard, or motherboard chipset for a more precise definition, supports PCIe 4.0 compatibility. In such a case, if you don’t have some PCIe 3.0-supported elements, these won’t work appropriately with your motherboard.


Overclocking is another aspect directly related to the chipset that is on your motherboard. The overclocking and performance of your system’s CPU, GPU, and RAM are directly attached to the chipset. Suppose there is a low-end or older chipset in your system. In such a case, you won’t be able to fully overclock and utilize the true potential of the components that are mentioned above. Hence, the motherboard’s chipset works so that all the components operate coherently and provide you with enough performance to do your chores. 

What are the types of motherboard chipsets?

During the early decades of technology, each baseboard was clad in discrete electronic components, with each chip controlling a certain machine element. Over time, technical inventiveness compacted the silicon transistor into the system’s chipsets: the motherboard chipset and the top portion, which are called for their designated locations on the microcontroller. It was simple to find a motherboard chipset on the motherboard when it featured a south bridge and a northbridge. There are typically two primary chipsets.

North-bridge connects the CPU to very fast peripherals, including RAM and graphics controllers. The north bridge was in place to regulate the CPU and connect it to the rest of the computer’s components, including RAM. We have all observed how frequently the more recent chipsets from Intel, Qualcomm, AMD, and others are better. We know what the CPU does, what the video card performs, and why we need an external hard drive. Moreover, we can explain how the motherboard’s chipset performs and how they vary from one another.


Southbridge manages data transfer between slower peripheral devices connected via PCI, ISA, USB, and IDE controllers. Southbridge is sometimes referred to as the I/O controller, I/O controller hub (ICH), or extension controller. Southbridge examines signals from peripheral component connections and ISA connections and may include important information, such as a service pack, along with other things. The primary role of southbridge is to control the operation of the IO.


A motherboard’s chipset must monitor data flow between components. A chipset is essentially the electrical component that connects with the rest of the system. To send and receive data, CPUs and memory cards must connect via the motherboard’s chipset. Modern motherboards have integrated chipsets that enable components to interact with one another. Previously, though, smaller chips were employed for each component. The chipset is responsible for connecting the other components to the circuit board.

Frequently Asked Questions

How to identify a computer chipset?

Many of our customers asked us how to identify a computer chipset. Well, the whole process for making this finding consists of a few steps. We’ll explain how to determine which chipset is installed on your Windows PC. Follow this process step-by-step to make things easy. 

Step 1: Press the Windows logo + X to open a menu section. 
Step 2: Go to the Device Manager section, which would be the sixth option on the list. 
Step 3: Scroll down until the end, and locate the System devices > expand it by a double-click. 
Step 4: Locate an option with the term ‘Chipset‘ with it—this is your motherboard’s chipset.

What type of chipset should you use?

You have undoubtedly heard the phrase “chipset” batted about when discussing new computers, so what precisely is a chipset, and how does it change the performance of your computer? In a word, a chipset decides which components, including the CPU, RAM, and graphics cards are compatible with the motherboard. A high-end, full-featured chipset is more expensive than a low-end chipset. When you create a computer, you choose the components that will go into it. 

Similarly, certain chipsets will give the functionality you desire, while others may not. Most chipsets support the many components you wish to use. Many formerly independent components’ capabilities are now included in modern chipsets on motherboards. The system chipset is responsible for several things, including efficient data transfers and rapid extension bus support. You should consider your demands and use trends before purchasing a device.

What is a chipset on a motherboard?

A motherboard is undoubtedly an unsaid hero when you’re playing games or creating content. The chipset fitted on it is the overall performance hub in such a situation. If you want to know what is a chipset on a motherboard, a chipset serves as the motherboard’s communications center. It also acts as a traffic controller, determining which components, including the CPU, RAM, hard drives, and graphics cards, are compatible with the motherboard.
