Choosing among CPUs, motherboards & memory starts with one practical question: are you building around AM5 and DDR5, staying with AM4 and DDR4, or adding a single desktop-memory module? The four choices here cover those different jobs, so the right pick depends more on platform fit than on price alone.
The listed prices span a $100.00 spread. MSI's B850 board is the lower-priced AM5 route, while the AORUS X870E board adds Wi-Fi 7 and other named features. The MSI B550 board serves an AM4/DDR4 system, and the SK hynix module is for a memory-only purchase.
Quick take
- AM5 and DDR5 at the lowest listed price: MSI B850 GAMING PLUS WIFI6E at USD 134.99.
- AM5 with Wi-Fi 7 and AMD EXPO: AORUS X870E PRO ICE at USD 199.99.
- AM4 and DDR4 for supported Ryzen generations: MSI MAG B550 Tomahawk MAX WiFi at USD 167.99.
- A single 16GB DDR5 desktop-memory module: SK hynix Lenovo PC5-5600B UDIMM at USD 234.99.
Listed-price comparison
| Product | Listed price | Price bar | Platform or format |
|---|---|---|---|
| MSI B850 GAMING PLUS WIFI6E | USD 134.99 | AM5, ATX, DDR5 | |
| AORUS X870E PRO ICE | USD 199.99 | AM5, ATX, DDR5 | |
| MSI MAG B550 Tomahawk MAX WiFi | USD 167.99 | AM4, ATX, DDR4 | |
| SK hynix Lenovo 16GB PC5-5600B UDIMM | USD 234.99 | 16GB UDIMM, DDR5 |
Decision matrix
- Choose the AM5 path if your processor plan is AMD Ryzen 9000, 8000, or 7000. The MSI B850 emphasizes the lower listed price, while AORUS adds Wi-Fi 7, AMD EXPO, and X870E.
- Choose the AM4 path if the system uses a supported Ryzen 5000, 5000 G, 4000G, or 3000 processor and DDR4 memory. The MSI MAG B550 is the only board here built around that platform combination.
- Choose the memory path if the purchase is specifically for a single 16GB DDR5 UDIMM with PC5-5600B bus speed. The SK hynix module does not replace a motherboard choice.
Product notes
MSI B850 GAMING PLUS WIFI6E AM5 AMD B850 SATA DDR5 Motherboard

The MSI B850 GAMING PLUS WIFI6E is the clearest AM5 starting point when the build needs an ATX board with DDR5 and AMD B850. Its AM5 socket covers Ryzen 9000, 8000, and 7000 processors, and the board includes four DDR5 DIMM slots plus a PCIe 5.0 M.2 slot. That combination gives the choice a defined platform and storage path without moving to the X870E model. The trade-offs are concrete: it is open box, and its connectivity name is WIFI6E rather than the Wi-Fi 7 called out for AORUS. Choose it for the lower-priced AM5 route when open-box condition fits the build plan.
AORUS X870E PRO ICE AM5 ATX DDR5 PCIE WIFI 7 AMD EXPO Gaming Motherboard

AORUS X870E PRO ICE suits an AM5 build where Wi-Fi 7, AMD EXPO, and multiple PCIe 5.0 storage options are part of the brief. Its ATX form factor and four-slot dual-channel DDR5 support keep it in the same broad board category as the MSI B850. The reason to choose it is the combination of X870E, Wi-Fi 7, and AMD EXPO named for the board. The limitation is its open-box condition, plus a lane caveat: populating certain secondary PCIe 5.0 M.2 slots may reduce the primary x16 graphics slot to x8 mode. That matters for a storage-heavy build with several high-speed slots in use.
MSI MAG B550 Tomahawk MAX WiFi Gaming Motherboard AM4 DDR4 ATX

MSI MAG B550 Tomahawk MAX WiFi Gaming Motherboard AM4 DDR4 ATX fits a different decision: keeping the build on AMD's AM4 and DDR4 platform. Its processor support covers Ryzen 5000, 5000 G, 4000G, and 3000 series, while the board also names PCIe 4.0, a Lightning Gen 4 x4 M.2 slot, 2.5G LAN, and Wi-Fi 6E. Those specifics make it a focused match for a Ryzen 5000-series parts list rather than an AM5/DDR5 plan. It is marked new, separating its condition from the two AM5 boards and the memory module. Its concrete limitation is platform scope: AM4 and DDR4 are defining requirements.
SK hynix Lenovo 16GB PC5-5600B UDIMM DDR5 Desktop Memory RAM HMCG78AGBUA081N

SK hynix Lenovo 16GB PC5-5600B UDIMM DDR5 Desktop Memory RAM HMCG78AGBUA081N addresses a different need from the three motherboards. The reason to choose it is its single 16GB UDIMM format with PC5-5600B bus speed, giving a memory-focused shopper a clear capacity and form factor. The limitation is equally clear: it is one stick, and the condition is open box. Its listed price is the highest of the four, so it makes sense when a 16GB UDIMM is the intended purchase rather than a motherboard platform change. It does not provide the socket, expansion, or networking features found on the board choices.
Final recommendations by use case
- For an AM5 build with DDR5 and the lower listed price: choose the MSI B850 GAMING PLUS WIFI6E.
- For AM5 with Wi-Fi 7, AMD EXPO, and X870E: choose the AORUS X870E PRO ICE, while accounting for its secondary-M.2 lane caveat.
- For a supported AM4 Ryzen system using DDR4: choose the MSI MAG B550 Tomahawk MAX WiFi.
- For a single 16GB DDR5 desktop-memory module: choose the SK hynix Lenovo PC5-5600B UDIMM.
