MSI B660 Roundup – Allround-PC

Before we go into the individual models, we would like to briefly mention a few common properties. We compared the MSI MAG B660 Tomahawk WiFi DDR4, MSI MAG B660M Mortar DDR4, MSI MAG B660M Bazooka DDR4 and MSI Pro B660M-A DDR4.

Thanks to the LGA1700 socket, they all support the Alder Lake processors up to the Intel Core i9. The four mainboards each have four DIMM slots for up to 128 gigabytes of DDR4 memory. According to MSI, the main memory can be overclocked to a maximum of 4,800 megahertz (one module). All offer two PCIe x16 slots, the primary of which supports PCIe 4.0, and one PCIe x1 slot. HDMI 2.1, DisplayPort 1.4 and 2.5 Gigabit/s Ethernet are always available .

The B660 Tomahawk clearly takes some aesthetic inspiration from MSI’s Unify range. Both share a black, RGB-less design that will easily blend into most systems.

The primary slot is a x16 slot that supports PCIe 4.0, the second is a x16 slot (x4 electrical) that supports a PCIe 3.0 and finally there’s a PCIe 3.0 x1 slot.
