About this deal

It's an extreme motherboard as well, the 16 teamed 110A powerstage vcore VRM is no joke, there's two PCIe 5.0 M.2 slots, USB4 support, loads of USB ports, onboard buttons, debug LED codes, 2.5 Gbit LAN and WiFi 6, it's an impressive but also ultra expensive mATX motherboard. For the stress test, we're using Cinebench R23 looped for an hour, at which point we're reporting the maximum PCB temperature recorded using the k-type thermocouples. 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.

And well, the good news is you don't have to worry about VRM thermals with X670 boards, not even a little. In the past, we've seen boards that should perform well fail miserably in this testing, but that's not the case here...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 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). Over the past few months we've been gathering as many AMD X670 motherboards as we could to test their VRM performance and to see if they can all handle the Ryzen 9 7950X without any kind of thermal throttling, something we ran into with a number of X570 motherboards a few years ago. Of course, it is an X670 Extreme board so you get PCIe 5.0 for the primary PCIe slot, which is nice, there's also a second PCIe 5.0 M.2 slot and the VRM has been upgraded with 105A powerstages from the 60A models used by the Elite AX but really that's going to be of benefit for very few people.

For recording temperatures we're using a digital thermometer with K-Type thermocouples and we'll be reporting the peak rear PCB temperature. Finally, we're not reporting Delta-T over Ambient, instead I maintain a room temperature of 21 degrees and to ensure a consistent ambient temperature a thermocouple is positioned next to the test system. 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.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. You also get USB4 support, 10 USB ports on the I/O panel, high quality external audio, two M.2 ports, 2.5 Gbit LAN and WiFi 6E, so it's a super well equipped ITX motherboard, but of course it's not exactly cheap. The best high-end X670E motherboard is simply the MSI MEG X670E ACE. The stupid expensive Asus ROG Crosshair X670E Extreme and MSI MEG X670E Godlike are excellent motherboards, but we can't justify the asking prices, especially in the case of the Godlike.

Essentially both boards have the same amount of PCIe bandwidth, the Carbon can just better spread that bandwidth across multiple slots while almost 90% of the PCIe bandwidth of the F Gaming is eaten up by the primary PCIe 5.0 x16 slot. These are great news to share: there are no bad X670/X670E motherboards. Surely prices might be a bit hard to swallow, but there are no duds, and that's a rare thing when reviewing an entire motherboard series. We hope you found this useful and expect a similar piece covering B650 motherboards. Shopping Shortcuts: Asus is the only brand to offer a Mini-ITX X670E board, and they're also the only brand to also offer a MicroATX X670E board. So that means we have one Mini-ITX, one MicroATX and 20 ATX boards on hand.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.
