Picking CPUs, motherboards & memory gets difficult when several boards appear plausible but belong to different processor and RAM routes. The useful payoff is simple: lock the CPU socket and memory generation first, then use format and named ports or networking to break the tie. These four boards divide between two AMD paths and two Intel paths, so price should be the final filter-not the opening one.
Quick take
The AORUS X870E PRO ICE carries the highest listed price, while the ASUS PRIME H310M-A R2.0 carries the lowest. Between them, the MSI Z390-A PRO and MSI MAG B550 Tomahawk MAX WiFi are priced fairly close together but target separate build directions. Do not treat the two MSI boards as substitutes simply because their prices are near: processor route, memory type, format, and named extras are the meaningful separators.
Listed-price comparison
| Motherboard | Listed price | Relative listed price |
|---|---|---|
| MSI Z390-A PRO | USD 172.21 | |
| AORUS X870E PRO ICE | USD 199.99 | |
| MSI MAG B550 Tomahawk MAX WiFi | USD 167.99 | |
| ASUS PRIME H310M-A R2.0 | USD 43.96 |
Decision matrix
- AMD AM5 with DDR5: Choose the AORUS X870E PRO ICE when the build is centered on this socket-and-memory route.
- AMD AM4 with DDR4: The MSI MAG B550 Tomahawk MAX WiFi is the direct match for this established AMD combination.
- Intel LGA1151 for 8th- or 9th-generation processors: The MSI Z390-A PRO is the relevant Intel option.
- MicroATX with listed DVI and VGA outputs: The ASUS PRIME H310M-A R2.0 fits this specific format-and-port requirement.
Product notes
MSI Z390-A PRO
The MSI Z390-A PRO calls out M.2 and USB 3.1 alongside an ATX layout, giving it a clear role for a parts list that specifically needs those named connections. Choose the Z390-A PRO when those connection labels matter as much as the Intel route in the decision matrix. The board is also identified as supporting dual-channel memory, which helps clarify the intended memory arrangement. Its limitation is cost: USD 172.21 sits close to the top of the listed-price range, so it is not the entry-price choice for a shopper comparing these four boards primarily by cost.
AORUS X870E PRO ICE
The AORUS X870E PRO ICE is suited to a build that calls for Wi-Fi 7 and AMD EXPO. Its description also specifies four DIMM slots and extensive PCIe 5.0 storage options, while on-board audio is listed among its features. Choose the AORUS board when Wi-Fi 7, AMD EXPO, and a four-slot memory arrangement are named priorities in the build plan. The tradeoff is its open-box condition, and USD 199.99 is the highest figure in this comparison. That makes the feature set, rather than price alone, the central reason to select it.
MSI MAG B550 Tomahawk MAX WiFi
The MSI MAG B550 Tomahawk MAX WiFi makes its case through PCIe 4.0, a Lightning Gen 4 x4 M.2 connection with M.2 Shield Frozr, and an AMD Wi-Fi 6E solution. The description also names 2.5G LAN, giving the board several explicit connectivity points for a shopper assembling around that mix. Its USD 167.99 listed price places it far from the lowest figure here, so the argument for this MSI model rests on those specified features rather than price alone. That is the key limitation in a cost-first comparison.
ASUS PRIME H310M-A R2.0
Choose the ASUS PRIME H310M-A R2.0 when two DDR4 SDRAM slots are the memory layout you want. That straightforward configuration makes the intended memory arrangement explicit rather than leaving it to guesswork. At USD 43.96, it is the lowest listed price in the group, making it the starting point for a cost-first comparison. The limitation is its used condition, a clear consideration beside the new-condition MSI MAG B550 Tomahawk MAX WiFi. For the stated slot count and low listed price, it is the most distinct alternative in the group.
Final recommendation by use case
Match the AORUS X870E PRO ICE to an AM5 DDR5 build. Choose the MSI MAG B550 Tomahawk MAX WiFi for an AM4 DDR4 parts list, and reserve the MSI Z390-A PRO for an Intel LGA1151 system using an 8th- or 9th-generation processor. Pick the ASUS PRIME H310M-A R2.0 for a MicroATX build that specifically needs DVI and VGA outputs. The right board is the one that keeps the processor, memory, layout, and named connections on the same path.
