Motherboard: What is it and which one to buy

The motherboard is perhaps the component that is most underestimated in the choice of the new PC, especially by users who are not particularly familiar with this world. After having explained to you which processor to buy and which RAM memory to buy, it’s also time to go on to explain you how to choose the motherboard.

This component will be one of those that most of all will decide the fate of your PC. In other words, if you plan to upgrade the desktop computer in the future, it will be the choice of the motherboard that will allow you to install the latest products or not.

What is a motherboard?

If you open the case of a fixed PC, you will immediately notice a different card from the others on which all the components inside it are cases. The motherboard acts as a link and not only for all those hardware parts used in a modern computer.

On its surface, there are slots for processor, RAM memory, video card and many more. All the microcircuits that you see in evidence, are a bit like the nervous system, as a transport channel for the electrical impulses that allow the various parts present to exchange information.

On the motherboard, even the most economical, are always present:

  • A socket, which allows you to host the processor and is different depending on the CPU family.
  • Slot for external cards, such as video, audio or RAM. These are also of different types and shapes depending on the intended use.
  • The capacitors, transistors and printed circuits, which constitute the communication routes, intersections and traffic lights of a hypothetical urban traffic.
  • The chipsets and inputs for external peripherals, which allow you to connect monitors, speakers, Ethernet cable, keyboard and mouse.

How to choose a motherboard

Choosing a motherboard, as we said at the beginning, is not always so simple. Its importance is fundamental for the life of the PC, and will make it last more or less time, depending on the model chosen.

The first element to consider, especially depending on which cases to buy, is the format of the motherboard. This component covers all the dimensions of existing computers, from Mini-PC to Full Tower, adapting accordingly to the available spaces.

As you can see, there are five variants of a motherboard available. In addition to dimensions, the number of doors and slots on its surface changes. If in an ATX format, you will have a maximum expansion available for peripherals, the same cannot be said for Mini, Nano and Pico-ITX.

These are designed for minimal solutions, such as Mini-PC or particularly small case. Our advice is to always choose an ATX motherboard or Micro-ATX limit if the case you own or want to buy cannot accommodate a larger one.

How to choose a motherboard socket

The socket is one of the most important components of the motherboard, that part where the processor is case. The type of socket on the motherboard you want to buy will also be decisive for the choice of processor.

The technical evolutions have meant that over time, the housings for the CPUs changed considerably, effectively preventing the use of the most-recent ones on older motherboards and vice versa.

AMD Socket

AMD is the company that together with Intel controls the CPU market. The motherboards designed to host these processors can have different types of sockets. The two main types currently used are AM4 and TR4.

AM4 was launched in 2016 and can host AMD processors with Zen and Excavator architecture. This means that you will find first-generation Athlon and Ryzen among the supported CPUs. TR4 is instead of the most-recent socket architecture, developed specifically for the Ryzen Threadripper family, high-performance CPUs that need a special housing.

Keep in mind that with the launch of the new Ryzen, AMD finally seems to have filled the gap that separated it from Intel. It could be a smart move to focus on this new generation of processors, among other things cheaper than the Intel counterpart.

Intel socket

Intel has outperformed AMD for years, producing processors with significantly better performance, albeit at a higher cost. Although the gap has narrowed, choosing an Intel CPU still means equipping your PC with an absolute quality component. Again, you will need a motherboard with a dedicated socket.

Currently, Intel produces processors that interface with three different types of sockets: 1151, 2011-v3 and 2066. If the 1151 socket is designed to accommodate slightly more outdated CPUs, that is those of the Skylake and Coffe Lake series, it is not can say for the other two. 2011-v3 and 2066 make it possible to use Intel processors with Kaby Lake and Cascade Lake architecture.

Which motherboard to choose

After this brief introduction, where we explained how to choose a motherboard, it’s time to see the most interesting models on the market. We have decided to insert three motherboards for each currently available socket, in order to give you the possibility to choose the model that best suits your budget.
