For most AM4 gaming builds in 2026, a B550 board such as the ASUS TUF Gaming B550-PLUS, MSI MAG B550 Tomahawk or Gigabyte B550 AORUS Elite V2 is the sensible choice, while an X570 board only makes sense if you need extra PCIe 4.0 lanes or more M.2 and USB connectivity. AM4 is a mature, DDR4-only platform, so the real decisions are chipset, BIOS support for your Ryzen chip and which features you will actually use.
Who still buys AM4 and why
AM4 remains attractive for two kinds of buyers: owners upgrading an older Ryzen system with a Ryzen 5000 chip such as the 5600, 5700X3D or 5800X3D class, and budget builders who already own DDR4 memory. The platform is mature, stock BIOS support for the 5000 series is well established on 500-series boards, and DDR4 kits cost less than DDR5 kits. The trade-off is that AM4 is a closed upgrade path. AMD’s newer desktop processors use the AM5 socket and DDR5, so a new AM4 build has no future CPU upgrades beyond what the socket already supports.

View on AmazonIf you are starting from scratch with no DDR4 on hand, compare the total platform cost against an entry-level AM5 build before committing. If you already own a Ryzen 3000 or 5000 chip and DDR4, a new board is mostly about replacing a failed or limited one.
Chipsets in plain terms
- A520: the entry chipset. Typically built for Ryzen 5000 at modest power, without chipset PCIe 4.0 and with fewer M.2 and USB options. Fine for basic builds, not ideal for a high-end chip.
- B450: older mid-range generation. Ryzen 5000 support depends on a BIOS update, which may need an older CPU or a flashback feature on the board.
- B550: the mainstream choice. Supports PCIe 4.0 on the CPU-connected GPU slot and first M.2 slot for Ryzen 5000 and 3000 processors, per ASUS’s specification page for the TUF B550-PLUS.
- X570: the higher-end chipset with more PCIe 4.0 lanes from the chipset itself, often more USB ports and M.2 slots, and active chipset cooling on many models.
At a glance
| Board | Chipset | Best for | Maker-listed highlights | Limits |
|---|---|---|---|---|
| ASUS TUF Gaming B550-PLUS | B550 | Reliable mid-range gaming build | Ryzen 5000/3000 support, four DIMM slots up to 128 GB DDR4, PCIe 4.0 x16, two M.2 slots, 2.5 Gb Ethernet | No built-in Wi-Fi on the base model; second M.2 is not PCIe 4.0 on the CPU lane |
| MSI MAG B550 Tomahawk | B550 | Strong power delivery and cooling for 8-core chips | Heavier VRM heatsinks and fast LAN aimed at higher-end Ryzen 5000 | Larger price tier than basic B550; confirm the exact revision |
| Gigabyte B550 AORUS Elite V2 | B550 | Balanced value with solid features | Full-size ATX board with PCIe 4.0 slots and multiple M.2 sockets | Check revision and BIOS version on the label |
| ASRock B550 Steel Legend | B550 | Budget to mid-range alternative | Full ATX board with a good I/O mix | Fewer premium touches |
| MSI MPG X570 Gaming Plus class | X570 | More lanes for multiple NVMe drives | Extra PCIe 4.0 lanes from the chipset | Chipset fan on some models; higher power draw than B550 |
| B450 Tomahawk MAX II class | B450 | Budget Ryzen 5000 upgrade | Pre-installed BIOS for Ryzen 5000 on later revisions | No PCIe 4.0 and weaker VRM headroom |
ASUS TUF Gaming B550-PLUS
The maker’s specification lists AM4 support for Ryzen 5000, 5000 G-series, 4000 G-series and 3000 series processors, four DIMM slots supporting up to 128 GB of DDR4 with rated speeds from 2133 MHz up to 4800 MHz overclocked depending on the processor, one PCIe 4.0 x16 slot for Ryzen 5000 and 3000, a chipset-driven PCIe 3.0 x16 (x4 mode) slot and three PCIe 3.0 x1 slots. It has two M.2 sockets supporting NVMe and SATA, with the first supporting PCIe 4.0 x4 on compatible CPUs, and a Realtek 2.5 Gb Ethernet port. It is the plainest example of a good B550 board: no unnecessary extras and widely stocked.
Limits are practical ones. This version has no built-in Wi-Fi, so a wireless user needs either the Wi-Fi variant or a PCIe or USB adapter. Only the first M.2 slot gets the CPU’s PCIe 4.0 lanes in typical B550 designs, so the second NVMe drive is best used as bulk storage.
MSI MAG B550 Tomahawk
MSI positions the Tomahawk as a step above entry B550 boards, with heavier VRM cooling and a feature set aimed at higher-end Ryzen 5000 processors. Reviewers regularly point it out as a board you can pair with an 8-core Ryzen 7 without worrying about power delivery. Check the exact board revision and BIOS version on the box because older stock may need a flash to recognise the newest 5000 chips.
Gigabyte B550 AORUS Elite V2
A full-size board with PCIe 4.0 support and multiple M.2 sockets. The V2 revision is the one to look for, because Gigabyte updated the layout and power delivery from the original model. Buyers often pick it when they want a balanced board without paying the Tomahawk tier. As with any older AM4 board, confirm the BIOS version on the label against the maker’s CPU support list for the chip you plan to use.
X570 and when it matters
X570 boards add extra PCIe 4.0 lanes from the chipset, which matters when you plan to run several fast NVMe drives, a capture card and a USB add-in card at the same time. Many X570 boards have chipset fans, which add a small noise source and a potential failure point. For a single GPU, one or two NVMe drives and a typical USB load, B550 gives you the same gaming performance because the GPU lanes come from the CPU. Choose X570 only for the connectivity.
Which AM4 CPU you are pairing
The board’s power delivery should match the CPU. Entry chips such as the Ryzen 5 5600 run fine on any B550 board. An 8-core Ryzen 7 5700X3D or 5800X3D benefits from a board with better VRM cooling, which is where the Tomahawk and AORUS Elite earn their place. The X3D parts have fixed multipliers, so overclocking features add nothing for them. A Ryzen 5000G series chip with integrated graphics runs PCIe 3.0 for the GPU slot and can also work on A520.
Compatibility and fit notes
- BIOS version: confirm the board shipped with a BIOS that recognises your Ryzen 5000 chip, or that it has a USB flashback feature.
- Memory: AM4 uses DDR4 only. Check the board’s qualified vendor list for the kit you plan to buy.
- Cooler mounting: AM4 coolers mount with the standard backplate. Check clearance around the VRM heatsinks for large air coolers.
- Form factor: full ATX for the boards above. Micro-ATX variants exist for compact cases, with fewer slots.
- Storage: count how many M.2 and SATA ports you need, and whether M.2 slots share bandwidth with SATA ports.
- Wi-Fi and Bluetooth: only the Wi-Fi variants include them.
Pick X if…
| Your situation | Pick |
|---|---|
| Simple gaming build, wired network, mid-range chip | ASUS TUF Gaming B550-PLUS |
| 8-core Ryzen 5000 with sustained loads | MSI MAG B550 Tomahawk |
| Balanced value with several M.2 slots | Gigabyte B550 AORUS Elite V2 |
| Several NVMe drives plus add-in cards | An X570 board |
| Tight budget, upgrading an older Ryzen 3000 build | B450 or A520 board with confirmed Ryzen 5000 support |

Budget tiers
Budget: A520 and B450 boards, suited to Ryzen 5 chips if the BIOS is up to date. Mid-range: B550 boards, the best fit for almost every gaming buyer. Premium: upper B550 and X570 boards with better power delivery, extra M.2 slots and faster networking. Since AM4 is no longer receiving new CPUs, spending at the premium tier is mainly justified by connectivity rather than future upgrades.
Alternatives to consider
If you do not already own DDR4, price an entry AM5 platform with a Ryzen 5 chip, because AM5 gives you a socket that AMD continues to support. If you want to stay on AM4, secondhand boards are common, but check for bent socket pins, a clean BIOS flash history and the revision number. For compact builds, look for B550 Mini-ITX boards, noting they carry fewer M.2 slots and fewer headers.
Frequently Asked Questions
Is AM4 still worth buying in 2026?
It is worth it if you already own DDR4 memory or an older Ryzen chip and want a low-cost upgrade. For a completely new build, compare against an entry AM5 platform, which gives a longer upgrade path.
B550 or X570 for gaming?
B550 is enough for nearly every gaming build, since the GPU slot and first M.2 slot get PCIe 4.0 directly from a Ryzen 5000 CPU. X570 is better only when you need more PCIe lanes, USB ports or M.2 slots.
Can a B450 board run a Ryzen 5000 chip?
Many B450 boards can, after a BIOS update from the maker. Check the board’s CPU support list for the exact revision, and make sure you can flash the BIOS before installing the new chip.
Do I need Wi-Fi on the motherboard?
Only if you cannot use a wired connection. Boards without Wi-Fi are usually the same board minus the wireless card, and a USB or PCIe adapter can cover the gap later.
Does the Ryzen 7 5800X3D need a special motherboard?
It needs an AM4 board with a BIOS that supports it. The chip locks its multiplier, so features aimed at overclocking do not add much. Good VRM cooling and a compatible BIOS matter more.
How much DDR4 memory should I pair with an AM4 board?
Two modules totalling 16 GB is the common baseline for gaming, with 32 GB for heavier multitasking. Use a kit listed on the board maker’s memory support page when possible.
