Hi again everyone! I'm sharing my comprehensive list of AM4-socket Motherboards (with X570 / X470 / X370 / B550 ^{(added June 2020}) / B450 / B350 / A320 chipsets). This sortable database aims to easily compare detailed specifications of all the different motherboard brands and models for AMD Ryzen CPUs (the link to the database opens to a shared Google Spreadsheet).

Each viewer can arrange or hide any data in the table to show only the models being considered through sorting/filtering the specific features and components one is looking for in an AM4 motherboard. (General instructions on how to sort and filter the only models you wish to see and compare are mentioned in the spreadsheet).

All information found in the table were researched and verified to the best of my ability based on manufacturer's data, user manuals, and reviews. I may update the table from time to time when new information are made available. If there are discrepancies/errors, let me know.

DEFAULT ARRANGEMENT OF THE DATABASE

When first viewed, the database is arranged in the following order of priority:

• By Chipset: X570 ---> X470 ---> X370 ---> B550 ^{(added June 2020}) ---> B450 ---> B350 ---> A320

• By Size / Form Factor: E-ATX ---> ATX ---> mATX ---> ITX ---> Thin ITX

• By Brand (Alphabetically): Asrock -> Asus -> Biostar -> ECS -> Gigabyte -> Msi

The above data can be seen in the left-most columns. Apart from the Brand/Model Name, a few other data are included at the main left-most columns such as: Photo of the motherboard, the Year (and Quarter) when the motherboard was made available, the Price Range, and a Subjective Tier ("ranking").

PRICE RANGE

This data shows the average approximate retail cost of the motherboard, indicated by a $ symbol. The first $ symbol means the board costs around $80 or lower, while the succeeding $ symbol thereafter is equivalent to an additional $40 each symbol over and above the $80 price tag. So,

• $ = ~$80 or lower

• $$ = From ~$80 to ~$120

• $$$ = From ~$120 to ~$160

• $$$$ = From ~$160 to ~$200

• $$$$$ = From ~$200 to ~$240, and so forth...

SUBJECTIVE TIER

This is a personal and subjective assessment on how the motherboard is "ranked" based on its features, specs, and quality compared to the models of the same brand. I have generally categorized motherboards in four (4) tiers, named and color-coded as:

• ENTHUSIAST (Green) Models

• HIGH PERFORMANCE (Yellow) Models

• MAINSTREAM (Brown) Models

• ENTRY-LEVEL (Magenta) Models
