ASRock B550 Extreme4 Motherboard Review

ASRock have released a wide range of motherboards based on the AMD B550 chipset, and we’ve been busy testing the whole product line and presenting each one of them to you. Today we’ll be taking a look at the B550 Extreme4. The Extreme4 series is well known for its great value and high performance. This is one of the reasons why it became a popular option for gamers over the years.

The Extreme4 looks similar to other ASRock’s motherboards, like the Velocita or the Steel Legend, but they all have significant differences. To find out what is unique in the B550 Extreme4 motherboard, you have to read our review.

If you’re not too sure what the main differences are between the X570 and the B550 chipset, here is an easy chart for comparison. Basically, the X570 offers full PCIe Gen4 support for both the general purpose lanes and CPU chipset uplinks, which will allow for faster performance, while the B550 can only provide PCIe Gen3 support for those lanes.

And to be honest, you won’t see that much of a difference in performance between the two. One of the B550 chipset advantages is that their motherboards are cheaper and attractively priced while offering similar performance to the X570.

I would like to thank ASRock for providing the review sample. This is a snippet from what ASRock has to say about themselves on their website:
