For most people, though, a less expensive board such as the ASRock X670E Taichi or Gigabyte X670E Aorus Master is a more sensible premium buy. X670 and X670E are an older AM5 generation now, so compare current prices with newer X870 and X870E boards before buying.
“Performance” here means power delivery for sustained workloads, memory and BIOS features, storage, networking, and expansion—not a promise of higher gaming frame rates. Premium X670E boards have generally tested close to one another in games; choose for the features your build will actually use.
Best X670 motherboards at a glance
| Board | Best for | Standout feature | Main trade-off |
|---|---|---|---|
| MSI MEG X670E ACE | Best overall features | 10GbE and three PCIe 5.0 M.2 connections reported in TechSpot’s comparison | E-ATX-class size and flagship positioning; verify case fit and current price |
| ASRock X670E Taichi | High-end value and mixed storage | 40Gbps USB4 and eight SATA ports reported in comparative coverage | Its value depends on current pricing and whether you need those connections |
| Gigabyte X670E Aorus Master | Balanced premium build | Two PCIe 5.0 M.2 sockets and a capable, power-efficient design in Tom’s Hardware’s review | Not the pick if you specifically need 10GbE or the most Gen 5 M.2 sockets |
| ASUS ROG Crosshair X670E Hero | Enthusiast tuning and gaming | Premium BIOS and tuning features, USB4, and broad Gen 5 support | 2.5GbE rather than 10GbE in TechSpot’s comparison |
| ASUS ROG Strix X670E-I Gaming WiFi | Mini-ITX builds | A compact X670E option | Compact expansion and access are inherently more constrained |
| ASUS ROG Crosshair X670E Gene | Micro-ATX enthusiast builds | A specialist compact X670E board | Two-DIMM compact layout; check the exact manual and current availability |
These are feature-based recommendations, not a current-price ranking. Historical review prices are not reliable indicators of what any board costs or whether it is in stock today.
Best overall: MSI MEG X670E ACE
The ACE is the easiest recommendation when a build can use its unusually broad connectivity. MSI lists a CPU-connected PCIe 5.0 x16 primary graphics slot, and TechSpot’s X670 comparison identifies three PCIe 5.0 M.2 connections and 10Gb Ethernet. That combination suits a Ryzen 9 workstation or gaming-and-creation system with several fast NVMe drives and a wired 10Gb network. See TechSpot’s X670 motherboard comparison and MSI’s ACE specifications.
#1 Best Overall
- AMD Socket AM5：Supports AMD Ryzen 9000 / Ryzen 8000 / Ryzen 7000 Series Processors
- DDR5 Compatible: 4*SMD DIMMs with ECC/Non-ECC Unbuffered Memory
- Commanding Power Design: Direct 16+2+2 Phases Digital VRM Solution, 8-Layer 2X Copper PCB
- Cutting-Edge Thermal Design: Advanced Thermal Design, M.2 Thermal Guard, Ultra Durable Armor
- Next Gen Connectivity: PCIe 5.0, Quad NVMe x4 M.2, USB-C, BT 5.2
Its advantages matter most when the rest of the system can use them: 10GbE requires a compatible network interface, switch or router, NAS or server, and suitable cabling. Multiple drives and add-in cards also make lane sharing and slot layout important. Consult the ACE manual’s lane-sharing tables before planning a GPU-and-storage configuration, and check that an E-ATX-class board fits the case, including clearance for connectors and cable routing.
Buy the ACE when its 10GbE, storage, and expansion justify the price over a simpler X670E or newer alternative. If you will install one graphics card, one or two SSDs, and use ordinary home networking, most of its premium capacity may go unused.
Best high-end value: ASRock X670E Taichi
The Taichi is a compelling alternative for a creator or workstation build that needs external high-speed connectivity and a large SATA array. Comparative coverage highlights integrated 40Gbps USB4 and eight SATA ports, alongside flagship-class expansion. Tom’s Hardware also noted its comparatively low launch price against extreme flagships, but that is historical context—not a current street-price guarantee. Read its X670E flagship comparison.
USB4 can be useful for fast external storage and docks, but do not assume it guarantees Thunderbolt certification or compatibility with every Thunderbolt device. Check the board’s exact specifications and the peripheral maker’s compatibility guidance. The Taichi makes most sense when it costs less than more extravagant flagships and those USB4 or SATA connections have a real job in your system.

The Aorus Master offers a strong feature set without chasing every flagship extra. Tom’s Hardware’s review describes it as well-equipped, capable, and power-efficient; comparative coverage lists two PCIe 5.0 M.2 sockets. It is a good fit for a premium gaming or productivity PC where two Gen 5 SSD positions are enough and 10GbE or integrated USB4 is not essential. See Tom’s Hardware’s Aorus Master review and its final analysis and feature discussion.

Prefer it when you find it materially cheaper than the ACE or Hero and its particular I/O matches the build. Before installing several drives or cards, check the exact board manual: available lanes and slot behavior can depend on which connectors are populated.
Best ASUS enthusiast choice: ROG Crosshair X670E Hero
The Hero is aimed at builders who value ASUS’s enthusiast BIOS and tuning tools, high-speed I/O, and a premium platform for memory and CPU experimentation. ASUS markets broad Gen 5 support, and Tom’s Hardware’s review covers its performance and firmware features. In one Far Cry 6 test, it posted the highest average result among the boards compared; the differences were small and do not establish a dependable gaming lead. See the benchmark results and the ASUS product page.
TechSpot’s comparison lists the Hero with 2.5GbE, not 10GbE, so it is a weaker match than the ACE for a 10Gb NAS or workstation network. Choose it for its controls and ecosystem rather than expecting a meaningful FPS uplift over other quality X670E boards.

Lower-cost X670 and X670E boards
Many builds do not need flagship networking, USB4, a large count of high-speed M.2 drives, or unusually extensive diagnostic features. TechSpot’s comparison includes the ASRock X670E PG Lightning, ASRock X670E Pro RS, ASRock X670E Steel Legend, and Gigabyte X670 Gaming X as lower-cost candidates. Current stock and pricing need checking before naming any one of them the best value. Use the comparison as a shortlist, then compare the exact model’s support page, manual, and I/O with its current price and newer alternatives.
For a typical single-GPU gaming PC with one or two SSDs, a lower-cost board with adequate power delivery and the ports you need is usually a better allocation of budget than paying for unused expansion. Do not assume a cheaper X670 board has the same PCIe 5.0 graphics or storage configuration as an X670E model; specifications vary by board.
Compact options: Mini-ITX and Micro-ATX
Mini-ITX: ASUS ROG Strix X670E-I Gaming WiFi
The Strix X670E-I is the compact-platform candidate for a small AM5 build. TechSpot identified it as the principal Mini-ITX option in its reviewed X670E field. Mini-ITX limits expansion compared with ATX: plan around the board’s available slots, storage, cooling, and case layout rather than assuming you can add cards later. Check current availability and the manufacturer’s exact specifications.
Micro-ATX: ASUS ROG Crosshair X670E Gene
The Gene is a specialist choice for a compact enthusiast system. TechSpot’s comparison identified it as the only X670 mATX board in that reviewed field; that is not a claim that no other model exists in the current market. Its two-DIMM layout and compact expansion profile make it important to check memory-kit compatibility and the number of add-in devices you need before choosing it.
X670 versus X670E—and whether to buy either in 2026
X670E is the more aggressively specified version, with stronger guarantees around PCIe 5.0 graphics and storage support. X670 can still offer excellent CPU performance and PCIe 5.0 storage, but the lane configuration and guarantees depend on the specific board. The chipset itself does not make a Ryzen processor faster at stock settings; the practical differences are connectivity, expansion, power delivery, memory support, firmware, and I/O. For many gaming PCs, paying extra for X670E solely for FPS is difficult to justify.
X870 and X870E are a newer AM5 motherboard generation. Compare a board’s actual ports, storage layout, CPU support, and price rather than assuming that a newer chipset is automatically the better fit. TechSpot’s X870 motherboard coverage provides context for the generation change. X670/X670E can still be worthwhile when discounted or when a specific board offers the SATA count, networking, or layout your build needs; if pricing is close, examine the newer option before committing.
What matters for sustained Ryzen 9 workloads
For a high-core-count CPU running long rendering, encoding, or compilation jobs, look beyond a headline VRM phase count. Power-stage quality, VRM cooling, firmware behavior, and workload temperatures all matter. The Aorus Master was described as capable and power-efficient in Tom’s Hardware’s review, while the ACE is a sensible flagship candidate for demanding Ryzen 9 systems. Those descriptions do not mean every Ryzen 9 needs a flagship board: a properly specified midrange board can be adequate, and no supplied comparison establishes one board as universally fastest under every sustained workload.

For overclocking or tuning, useful practical features include BIOS controls for Precision Boost Overdrive (PBO), Curve Optimizer, load-line calibration, memory settings, and diagnostics such as debug codes or POST LEDs. Check the exact model’s manual and firmware notes for the controls you plan to use. Better VRM capacity is chiefly valuable for sustained power delivery and headroom, not as an automatic gaming-speed upgrade.
Memory, EXPO, and boot behavior
All four-DIMM X670E boards do not necessarily run four populated DIMMs at the same speed as a two-DIMM configuration. Advertised high DDR5 speeds are overclocked memory settings, not universal guarantees; the processor’s memory controller, kit, board, BIOS, and number of modules all affect stability. DDR5-6000 is a reasonable starting point for many AM5 builds only when the CPU, kit, and BIOS support it. Check the board’s memory QVL, especially for high-capacity kits or ambitious speeds.
Enable AMD EXPO only after confirming the system is stable at default settings. Memory training after a reset or hardware change can take longer than a normal boot, so avoid repeatedly interrupting the first startup; use the board’s diagnostic LEDs or code display if the system appears stalled. If EXPO is unstable, return to defaults, update to a stable BIOS, test a two-module kit, enable EXPO without extra manual timings, and reduce the memory speed if errors continue. Run a memory test before relying on the system for important work.
As of 2026, some 600-series motherboard BIOS releases have added AMD EXPO Ultra-Low Latency options. This is a later firmware feature, not a launch-era X670 capability, and support depends on the exact board and BIOS. Check the board-specific release notes; see Tom’s Hardware’s coverage of the BIOS updates.

- After assembly, establish a stable baseline before enabling PBO, EXPO, or manual memory settings.
The Hero manual identifies the AM5 platform and directs users to the CPU-support list, illustrating why compatibility should be checked against current model-specific documentation.
Storage, PCIe lanes, and case fit
Do not assume every slot can run at full speed simultaneously. Installing multiple M.2 drives or expansion cards may share or disable lanes, or change how another slot operates. Before purchase, inspect the exact manual’s lane-sharing table and answer these questions:
- Is the primary graphics slot PCIe 5.0, and does populating another slot reduce its lane width?
- How many M.2 sockets are PCIe 5.0 versus PCIe 4.0, and are any supplied through an add-in card?
- Does an accessory card consume an expansion slot or require a proprietary component?
- Are all M.2 sockets heatsinked, and can a large GPU obstruct access to a drive or its heatsink?
- How many SATA ports remain usable with your chosen M.2 configuration?
Also check physical fit: board size, right-edge connector clearance, radiator and GPU clearance around heatsinks, and cable routing. The ACE is E-ATX-class, so an ATX case listing alone is not proof of compatibility.
Networking and external I/O
- 10GbE: Useful for fast workstation-to-NAS transfers when the other network equipment and cabling support it. The ACE is the clearest pick here among these recommendations.
- 2.5GbE: Adequate for many home broadband and gaming setups; it is the Hero’s listed wired networking tier in TechSpot’s comparison.
- Wi-Fi 6E and Bluetooth: Check the exact board’s specification, included antenna, and operating-system driver support. Wi-Fi 6E requires compatible client devices and a 6GHz-capable router to use 6GHz.
- USB4: The Taichi’s integrated 40Gbps USB4 is a notable advantage for supported docks and storage. Confirm peripheral compatibility rather than treating USB4 as an unconditional Thunderbolt guarantee.
- Service and diagnostics: Check rear USB speeds and count, front USB-C headers, BIOS Flashback, Clear CMOS, POST indicators, and audio outputs against your actual setup.
Buying checklist for older X670 stock
Because X670 boards launched years before the current buying window, listings may be old stock, refurbished, or used. Before ordering, verify:
