The MEG X670E ACE appears to be MSI’s high-end board for those that aren’t interested in spending a small fortune on the Godlike board and it should cater to just about all needs. The board has a 22+2+1 phase power design and MSI is using a heatpipe as well as a stacked fin-array heatsink and a MOSFET backplate to help cool the oversized power circuitry. Other features include 10 Gbps Ethernet, although there is only one Ethernet interface, a DisplayPort 1.4 compatible USB-C 10 Gbps port (which was said to be DP 2.0 compliant at Computex), as well as two 20 Gbps USB-C ports around the back. USB4 is nowhere to be seen, but is most likely related to ASMedia being late to the game with its host controller. MSI has gone for a design where the x16 PCIe 5.0 lanes from the CPU are split between the first two PCIe x16 slots and the third slot is using four lanes of PCIe 5.0 from the CPU. The final four PCIe 5.0 lanes from the CPU are for one of the M.2 NVMe slots and the board has a further three M.2 PCIe 4.0 slots. On top of that, MSI also includes an M.2 Xpander-Z Gen5 Dual add-in card that can accept a further two PCIe 5.0 NVMe SSD at the cost of eight PCIe lanes from the GPU.
The MPG X670E Carbon WiFi gets a slightly trimmed power regulation design with 18+2+1 phases and sadly loses the stacked fin-array heatsink, but does at least retain the heatpipe for the MOSFETs. MSI has also dropped the 10 Gbps Ethernet port in favor of a 2.5 Gbps port and the third PCIe x16 slot is only PCIe 4.0 on the Carbon. However, the Carbon gets two PCIe 5.0 M.2 NVMe slots onboard and has a further two PCIe 5.0 M.2 NVMe slots. IF you’re looking at taking advantage of the expected integrated graphics in the upcoming Ryzen 7000-series CPUs, then this might be the board for you, as it has an HDMI 2.1 port, a DP 1.4 port and a USB-C port with DP 1.4 support. There’s a second USB-C 20 Gbps port around the back as well. The MPG X670E Carbon WiFi looks like it should be a well rounded board for most people.
Finally the Pro X670-P WiFi gets a 14+2+1 power design and this time around MSI has dropped the heatpipe, although the company has still applied a rather large heatsink. MSI dropped most of the niceties on the Pro, as gone is the pre-attached I/O shield and not all M.2 slots come with heatsinks. Somewhat surprisingly, MSI includes a 20 Gbps USB-C port here and the display outputs are identical to the Carbon. This is the only board from MSI to offer up a PCIe 3.0 x1 expansion slot and as this is an X670 board, the three x16 slots are all PCIe 4.0, although the configuration is x16, x4 and x2, with none of the lanes being shared . The board has a single PCIe 5.0 M.2 NVMe slot and three PCIe 4.0 M.2 NVMe slots.
All three boards rely on eight-layer PCBs with two ounce copper layers. MSI has also included screwless M.2 drives installation on all boards, with the higher-end models also have screwless heatsinks on some of the M.2 slots. All three models also have a Realtek ALC408x USB audio codec, with the ACE gaining an ESS ES9280AQ DAC as well. Overall it looks like MSI is going to have a small, but pretty solid range of X670 and X670E motherboards.
