Let’s take a look at the MSI B350 TOMAHAWK, a mid-range motherboard with the AM4 socket, based on the AMD B350 chipset, supporting Ryzen and AM4 A-series CPUs. Check it out!
The AMD B350 chipset is the mid-range model for the AM4 socket, used by the Ryzen CPUs and the seventh-gen APUs. The B350 differs from the high-end chipset for this platform, the X370, by the number of PCI Express 2.0 lanes (six, against eight on the X370), USB 3.0 ports (two on the B350 and six on the X370), and SATA-600 ports (eight on the X370 and six on the B350).
Another difference is that the B350 doesn’t support splitting the 16 PCI Express 3.0 lanes into two slots (x8/x8 configuration) like the X370. So, the B350 is aimed at single-VGA systems.
Both the chipsets support two USB 3.1 ports, and RAID 0, 1, and 10.
You can see the MSI B350 TOMAHAWK motherboard in Figure 1. It uses the ATX form factor, measuring 12” x 9.6” (304 x 243 mm).
