The B450 chipset allows AMD to offer a range of inexpensive motherboards compatible with the latest 3rd generation AMD Ryzen processors. In addition, you can also upgrade your motherboard with future 4th generation Ryzen processors. The B450 therefore remains a good choice. That said, you won’t have access to PCIe 4.0, which could be a problem in the next few years.


How important is the motherboard?

It is aptly named since the motherboard is where all PC connections originate. Thus, each component is connected to the motherboard via a connection, or by being soldered. Therefore, it is imperative that each component is compatible , otherwise it cannot be connected or will not be functional.

The motherboard takes the form of a plate consisting of a printed circuit , connection ports and on which the chipset is soldered . There are different ranges of motherboards. The more you go upmarket and the more the card is compatible with the latest technologies, with the most recent and high-performance components, the more ports it has, and the more it can be upgraded.

However, prices can quickly rise. Thus, entry-level motherboards cost less than €50, when there are models over €800. The choice mainly depends on what you want to do with your PC. For office automation, an entry-level model is sufficient, but for applications requiring more resources (video games, video editing, 3D rendering, etc.), you have to turn to more efficient motherboards, and therefore more expensive. .

Nevertheless, it is recommended to choose a good motherboard from the start, in order to have a base with great scalability allowing you to gradually improve your PC by replacing certain components without changing the motherboard.

B450 motherboards: a good choice?

The ranges of motherboards depend on their chipset . It is he who defines what type of motherboard it is. It takes the form of one or more chips whose role is to ensure the operation of the motherboard and its components (memory bus, system bus, PCIe port, inputs/outputs, PCI bus, etc.).

The chipset defines whether or not the motherboard is compatible with this or that component and this or that technology.

As mentioned in the introduction, AMD and Intel are the two main chipset manufacturers. Each offers several ranges. The AMD B450 chipset is a mid-range model . It is aimed at users who need a high-performance PC allowing them to play recent video games, and to take advantage of resource-intensive applications, but who cannot or do not want to spend more than 1000€ on their PC. .

With a B450 motherboard, one can enjoy high-end components, but in limited numbers, while the latest high-end technologies are inaccessible. However, the ability to upgrade a PC with a B450 motherboard remains very interesting, especially since it is very versatile .

Prices for B450 motherboards vary from €65 to €250 depending on the model. The price difference is explained by the quality of the materials composing the motherboard and influencing its lifespan and performance. Additionally, more expensive motherboards often come with additional ports and features.
