It is X370 galore today it seems. AMD just launched 16 AM4 motherboards that will become available from five different manufacturers.

During CES, AMD showcased 16 cutting-edge high-performance AM4 motherboards from five manufacturers, including ASRock, Asus, Biostar, Gigabyte, and MSI. In addition, AMD exhibited Ryzen processor-based “extreme performance” PC designs from 17 top system integrators across the globe, as well as innovative third-party CPU cooler designs, demonstrating a ready and robust ecosystem for Ryzen CPUs.

AMD and its motherboard partners today debuted a wide array of new motherboards from ASRock, Asus, Biostar, Gigabyte, and MSI, all built upon two upcoming desktop chipsets for AMD Ryzen processors: the X370 and X300. X370 chipset-based motherboards are designed for those who need the most performance, cutting-edge features, and superior I/O connectivity from their PCs including support for overclocking, and dual graphics. For users looking for performance in a more compact size, the X300 chipset also features an AMD Ryzen-ready AM4 socket while utilizing the mini-ITX size ideal for small form factor PCs. Both chipsets take full advantage of innovative technology features including:

• Dual-channel DDR4 memory
• NVMe
• M.2 SATA devices
• USB 3.1 Gen 1 and Gen 2
• PCIe 3.0 capability

AMD is to release X370, B350 and A320 chipsets that are compatible with the upcoming RYZEN based processors (previously named ZEN). Socket AM4 evolves the PC infrastructure towards DDR4, NVMe M2 and USB 3.1 Gen 2 and sure, PCI Express 3.0 platform support. 

AMD X370 Chipset (High-End)

So the most high-end chipset will be the X370 with that X for Extreme. This chipset will support Multi-GPU rendering (Crossfire and SLI) with two full x16 PCI Express slots (Gen 3.0). The chipset will support overclocking. Basically this is the chipset series you and yours truly will be after once Zen releases and yes you can expect a dandy overclocking software suite.

AMD B350  Chipset (Mainstream)

If it has a B in the naming schema, you should think mainstream and that B for Business. A more generalized chipset that offers full performance, yet less tweaking options and often less PCI-Express lanes available, the mainstream series. For B350 some specs already have leaked, next tot the 8x Gen 3 PCI-Express lanes, it'll add/hook another 6 Gen 2 lanes  through the chipset and will offer a wide varyity of USB connectivity.  This motherboard series will offer 2 channel DDR4 memory we assume up-to 2400 MHz.

AMD A320 Chipset (SSF/Budget)

Then there is the A320 and A300 series. These are intended for value, budget and small form factor products. This chipset will offer 4 PCI-e Gen 2 lanes with 1+2+6 (USB 3.1 Gen2, USB 3.1 Gen1, USB 2.0) support. A300 should be the chipset for SSF computers (like tiny home theater builds etc). And with this round of chipsets AMD is to offer a complete range and line from top to bottom in the desktop PC segment, they are ready for ZEN alright.
