AM4 motherboard: learn how to choose the ideal model for Ryzen chips

0

There are several AM4 motherboard options for sale in Brazil. The chipsets are aimed at AMD’s Ryzen processors, and have differences that may be important according to the type of use desired. Therefore, it is also important to know the offerings of USB ports, high speed PCs and also the possibility or not of overclocking, as well as other advanced features. Check below the models available in the Brazilian market and learn how to choose the ideal AM4 motherboard for your new PC with AMD processor.

Input cards: A300 and A320
The A320 chipset appears in motherboard options for Ryzen processors, in addition to the latest AMD APUs with socket AM4, focused on cost-effectiveness. Simpler, this platform does not allow overclocking, nor does it support PCIe 4.0. Thus, using PCIe 3.0, the model offers 24 high-speed tracks, enough for just one NVMe SSD. In terms of USB, the A320 supports a USB 3.2 Gen2 port, a USB 3.2 Gen1 port and six USB 2.0 ports. From the storage point of view, the card is capable of having three SATA interfaces, one of which is of the Express type.

Another detail that consumers need to consider is that A320 cards vary when it comes to supporting the latest Ryzen processors. Models like the Ryzen 5 3500 may not work on an A320 card, even if they fit physically in the socket. When in doubt, the best solution is to consult the documentation of each manufacturer to find out if the latest CPUs are fully compatible. Prices, in turn, start at around R $ 369 in the national market.

The A300 chipset offers more or less the same feature profile. The big difference is that this option appears on very compact boards, aimed at minimalist installations. Thus, the pattern may be common in notebooks with an entry proposal.

Intermediate plates: B350 and B450
One of the highlights of these sockets is the overclocking support on any Ryzen processor. Although they are restricted to the third generation PCIe, both B350 and B450 offer a great advantage over the A320, as they have 28 high speed tracks, something that allows a computer with more versatility in peripherals.

Regarding the USB ports, both chipsets guarantee two USB 3.2 Gen2, two USB 3.2 Gen1 and six USB 2.0 ports. There are also three SATA interfaces for hard drives and SSDs, one of which is the Express standard.

As they appear on boards compatible with different types of use and in different price options, chipsets can be used in various products. Its prices are around R $ 379, for Biostar B350ET2, or R $ 540, for Asus Prime B450M Gaming.

Top of the line cards: X370, X470 and X570
The premium options are compatible with all three generations of Ryzen chips currently available. The X-line chipsets offer more features, more advanced hardware support, as well as appearing on higher priced motherboards.

The three allow for overclocking and, in the cases of X370 and X470, 38 ways of PCIe 3.0 are supported, which should be enough to use two video cards at the same time. The X570, more recent and created in conjunction with the Ryzen 3000, offers PCIe 4.0 and 40 high-speed tracks, a relevant advantage for those who want to build a powerful computer with a good useful life.

The X370 and X470 versions can have two USB 3.2 Gen2 ports, six USB 3.2 Gen1 ports and six USB 2.0 ports, while the X570 is compatible with up to eight USB 3.2 Gen2 and four USB 2.0 ports. Regarding SATA ports, the first two have six interfaces, two of which are Express type. The more robust option, on the other hand, has a total of 12 SATA ports.

As they are the most advanced chipsets, X370, X470 and X570 are present in the most expensive motherboards for Ryzen processors. Prices can vary widely, but the most affordable options with the X470 platform are around R $ 779 at the moment. Top of the line cards, such as Gigabyte X570 UD, for example, appear in the range of R $ 999 in the Brazilian market.

How to choose the best one?
At the moment, AMD chipsets are quite competitive, but there are some features that can make a difference when buying. After considering your budget, the first one is the type of use you want for your PC. Games, productivity and even access to advanced functions, such as overclocking, can be served by the B350 and B450 lines at affordable prices.

An interesting point to note is the use of PCle 4.0. The technology is not yet as common as the third generation of the standard, but its support on the motherboard could mean a PC with a longer life. This is because the latest version guarantees the high performance of more powerful graphics cards and SSDs, and if it is possible to spend a little more, the X570 will allow the system to be upgraded for a few more years.

Another possibility is to wait for the launch of new motherboards aimed at Ryzen 4000 processors, since the expectation is that even intermediate models, with B350 chipsets, for example, offer support for PCle 4.0.
