Usually we'd go over each motherboard, talk about the key features, the heatsinks, and the VRM components, but we've got 22 boards, so spending a few minutes on each one isn't all that interesting for this roundup. Instead we'll jump straight into VRM thermal testing, then brush over a spec comparison table, before making some actual board recommendations, so let's get into it. Test System and Notes An expensive motherboard but worth it if you will use the extra features. By far the biggest draw for this board (as another reviewer pointed out) is that is does not take away from the GPU lanes if all NVME/Sata slots are populated. This is massive compared to most other AM5 boards if you hold a lot of data/media. I originally had a Strix motherboard but felt like I could never use the 4th slot, which kind of defeated the point of having it. SMT (Surface Mount Technology) PCIe slot diminishes interference and electrical noise and fully supports the PCIe 5.0 signal.All the motherboards are fairly advanced, but the flagship MEG-series come with M.2 Xpander-Z Gen5 Dual SSD adapter cards that add two M.2-2280 slots for SSDs and therefore enable a rather formidable storage system. In addition, the MEG X670E Godlike comes with an M-Vision Dashboard LCD that displays the status of the rig and allows system tuning with touch control. LAN with LAN Manager, BlueTooth 5.2, and AMD Wi-Fi 6E Solution: Upgraded network solution for professional and multimedia use; delivers a secure, stable, and fast network connection

Aluminum Cover with Extended Heatsink: All-metal extended heatsink cover enlarge the surface of heat dissipation, ensures even high-end processors to run in full speed. Lightning Fast Game Experience: PCIe 4.0, Triple Lightning Gen4 x4 M.2 with M.2 Shield Frozr, StoreMI, AMD Turbo USB 3.2 Gen2. Still, if you were to use PCIe 5.0 devices this configuration would make the most sense, as both delivers would receive x8 PCIe 5.0 bandwidth which is 32 GB/s. In comparison the Asus ROG Strix X670E-F Gaming connects its secondary PCIe x16 slot chipset, which is a lot cheaper to wire in, but does limit you to PCIe 4.0 x4 bandwidth (8 GB/s). Maximum 6 x M.2 Connectors: Onboard and exclusive M.2 XPANDER-Z GEN5 DUAL PCI-Express card offer totally sextuple M.2 connectors for the maximum storage performance. The double-sided Shield Frozr design keeps M.2 SSDs safe while preventing throttling, making them run faster. For some reason Gigabyte spent their PCIe 5.0 budget on the M.2 drives, limiting the PCIe slot support to a single x16 slot. So while we guess four PCIe 5.0 M.2 slots is nice, we'd rather have the flexibility of having more PCIe slots.In the same price range, the Asus ROG Strix X670E-I Gaming WiFi wins the award for the best X670E Mini-ITX motherboard by default, as it's the only one as does the Asus ROG Crosshair X670E Gene for the best and only Micro-ATX motherboard.

M-Vision Dashboard: The Touchable 4.5-inch full-color IPS LCD not only indicates the status of your gaming rig which combines hardware monitor and debug function, but also allows system operation and customization with touch control. Special thanks to MSI for providing us with the MPG X670E Carbon WiFi Motherboard motherboard to review.

In the past, we've seen boards that should perform well fail miserably in this testing, but that's not the case here... Unlike the MSI MEG X670E ACE, the feature set on the MPG X670E Carbon WiFi is more modest, which has:

Let's talk about test conditions first. For this testing we've built a dedicated system inside the Corsair iCUE 7000X case. Powering it we have the HX1000 power supply and for cooling the Corsair iCUE H170i Elite Capellix.As a gaming oriented motherboard, the heatsinks are sharp and angular, giving it a more aggressive look. The ROG Strix X670E-I Gaming is an impressive ITX board, using ten 110A power stages for the vcore it ran very cool and although it features active cooling it was always silent in our testing. Admittedly, we tested it under the same conditions as all the other boards, so in a cramped ITX case it will likely run a bit hotter, but we're confident it's up to the task. A few things to note. Any temperature below 80c is to be considered very cool, VRM temps only start to become a concern when they exceed 90c, and even then there's still 10-20c worth of headroom before most boards will thermal throttle. Below 80c is very safe and will never present an issue, so all X670 boards are well within safe limits.
