A520 vs B550: Socket and CPU Compatibility
Socket type supported
How do we determine which processor is compatible with which motherboard? Can we buy any processor on the market and connect it to our motherboard? The simple answer is no.
All motherboards come with a specific CPU connector. This essential part establishes a connection between a processor and a motherboard. It is called a socket.
In short, the socket helps us determine which CPU is actually suitable for our motherboard. For instance, you can’t place an Intel processor into an AMD socket and vice versa.
Both the A520 and B550 support the AM4 socket. So, if you want to equip your motherboard with an AMD processor, either of these two chipsets is the right choice for you.
Okay, we have determined that the A520 and B550 chipsets support AMD processors. But are these chipsets compatible with all AMD CPUs? Let’s find out more from the table below.
|AMD Athlon with Radeon Graphics||No||No|
|AMD Ryzen 1000||No||No|
|AMD Ryzen 2000 with Radeon Graphics||No||No|
|AMD Ryzen 2000||No||No|
|AMD Ryzen 3000 with Radeon Graphics||No||No|
|AMD Ryzen 3000||Yes||Yes|
|AMD Ryzen 5000||Yes||Yes|
As you can see, when it comes to this segment, both chipsets are similar. Whether you decide to buy an A520 or B550 motherboard, it will most likely support the latest AMD CPU models, such as AMD Ryzen 3000 or 5000.
Unfortunately, you can’t count on the older budget-friendly processors from the table above. If you are on a tight budget and don’t have enough money for the latest AMD CPUs, you can try a motherboard with the X470 chipset. This one supports older CPU models such as Ryzen 1000, Ryzen 2000 APU, or Ryzen 3000 processors.
Have you found a good computer case yet? How about fans? We are aware that the market is full of outstanding models enhanced with RGB lights and other premium features.
But before choosing a PC case, it might be a good idea to pay attention to its size. The most common PC case sizes are ranked from the Full Tower, Mid Tower, and Mini Tower to Small Form Factor.
And why is this important? Keep in mind that not all motherboards can fit into every case. This is why you should pay attention to this aspect when building your PC configuration.
Motherboards come in different shapes and sizes. They also have different numbers of ports and slots. In general, all these pieces of information represent a form factor.
There are three form factors — ATX, Micro ATX, and Mini ITX. The biggest and most common form factor is ATX.
Motherboards equipped with the A520 or B550 chipsets can have different form factors depending on the manufacturer. A520 motherboards are usually designed as ATX, while B550 models also use the Micro ATX form factor.
A520 vs B550: GPU Compatibility
SLI / Crossfire compatibility?
SLI and Crossfire technologies allow you to use multiple graphics cards simultaneously. For instance, if you have two free PCle x16 slots on your motherboard, you can use two extra cards to improve graphics performance. Almost all modern boards have at least one extra PCle x16 slot.
But is this everything you need to have to use this technology? No. There are more requirements. The most significant thing is that your motherboard supports this technology.
Some boards support SLI while others Crossfire. But what is the difference? In general, there aren’t differences between SLI and Crossfire. Both technologies have the same purpose — to deliver enhanced graphics performance. The term SLI comes from Nvidia, and Crossfire comes from AMD.
Last but not least, all graphics cards used in this manner have to be the same. In other words, they need to be identical by the model and number and not necessarily from the same manufacturer. They also need to be compatible with SLI or Crossfire technology.
Unfortunately, A520 doesn’t support SLI/Crossfire technology, as these are budget-friendly motherboards designed for basic gaming.
On the other hand, B550 motherboards support SLI/Crossfire graphics cards. So, if you want to use this technology, it might be a good idea to invest in a motherboard with this chip.
But keep in mind that not all applications and games support SLI or Crossfire. Therefore, check if you can benefit from this technology before you implement it.
A520 vs B550: Performance
There are many creative ways to get the most out of your computer components. Using SLI/Crossfire technology is one of them. However, the main disadvantage of this technology is that you still need to invest money to buy an extra graphics card or even a new motherboard.
Let’s say you want to enhance your existing computer component without investing money in a new one. Is that possible? Of course, it is! The process is called overclocking.
Overclocking allows you to increase the frequency of a computer component above its factory settings. That can be your CPU, RAM, motherboard, graphics card, or any other component which has a clock.
Although it sounds amazing that you can speed up a component, some problems may appear. One of them is overheating.
So, if you want to overclock any of your components, it might be a good idea to equip your rig with proper cooling systems. But before anything else, make sure to purchase a motherboard that supports this function.
The B550 chipset is an absolute winner in this segment since boards with this chip support overclocking.
Data transfer speed
Whether you need to connect an SSD disk or another external device to your computer, it is good to have a motherboard with fast data transfer speeds. In this section, we will determine which motherboard has higher data speed.
The picture above shows all the data transfer speeds you need to know when choosing a new motherboard.
Most A520 motherboards support USB 3.2 Gen1 speed or 5 Gb/s. However, if you want to reach a slightly higher data transfer speed, a B550 board might be a better choice. B550 motherboards usually support 3.2 Gen 2 speeds — 10 Gb/s.
But note that these speeds may vary from manufacturer to manufacturer. So, when choosing a product, read the specifications and find the right label from the image above.
Memory speed and compatibility
It is important to have fast memory speed because the RAM stores all program data. From the moment you turn on your computer and open several programs, RAM starts to store data.
For example, if you don’t have enough memory, your computer may become slow when trying to open an application. So, the more memory you have, the more data you can store.
|Memory Speed & Capacity||A520||B550|
|Maximum Speed||4733 MHz||5400 MHz|
|Maximum Capacity||128 GB||128 GB|
When it comes to memory capacity, each chipset in the A520 vs B550 comparison brings impressive results. Whether you choose an A520 or B550 motherboard, you can upgrade your PC up to 128 GB of RAM.
Besides memory capacity, it is also crucial to take memory speed into account. As you may know, the CPU and RAM exchange data to secure good system performance. If this connection becomes slow, you may also notice a drop in performance.
To support your CPU, you can choose motherboards that support higher maximum speeds. Therefore, the B550 chipset wins this segment since it supports speeds up to 5400 MHz.
A520 vs B550: Other Features
If you want to have a better WiFi connection, the solution can be a PCI-e WiFi card. Instead of using WiFi via a USB adapter, you can connect this card directly to the motherboard and have a better internet connection.
Both A520 and B550 motherboards support WiFi. But, again, it all depends on the motherboard manufacturer and model.
To claim a winner in this section, we decided to pitch two excellent models against each other. In this case, that would be the ASUS TUF Gaming A520M-Plus and MSI B550-A PRO ProSeries. Both models have a decent price and lots of exciting features.
|Features||ASUS TUF Gaming A520M-Plus||MSI B550-A PRO ProSeries|
