While the older 300-series chipsets from AMD support the new 2nd Generation Ryzen processors, there are some features limited to the 400-series chipsets. The high-end X470 chipset released with the new processors and soon the more mainstream B450 chipset will be releasing as well, and ahead of this release, Gigabyte is sharing what we can find on its upcoming motherboards.
For USB, SATA, and PCIe connectivity, the B450 chipset does not differ from the B370 chipset, but it does support both the Precision Boost Overdrive feature and StoreMI. With StoreMI the user can have SSDs and HDDs combined into a single drive, with content intelligently placed on the different physical media, depending on your behavior. The more you access specific files, the more likely they are to be placed on the faster SSD than those you rarely use that remain on the HDD.
Also coming with the new set of motherboards is a new naming scheme, with Gigabyte dropping the Gaming 7, Gaming 5, etc. convention to instead use the Xtreme, Master, Ultra, Pro, Elite, etc. convention also found with their graphics cards. For the B450 boards, the Aorus Pro WiFi is at the top offering dual band 802.11 AC WiFi. The B450 Aorus Pro is identical but lacks the built-in WiFi support. Both of these motherboards come with two m.2 heatsinks for their two slots, Intel 211AT LAN, ALC1220-VB audio, and an ATX (305 mm x 244 mm) form factor. A step down is the Aorus Elite that has Gigabyte Gaming LAN, only one m.2 heatsink (still has two ports), and no USB 3.1 Gen2 ports. The Aorus Pro boards have a Type-A and Type-C USB 3.1 Gen2 port in addition to the six USB 3.1 Gen1 and eight USB 2.0 ports. All three of these boards have an 8+3 Hybrid Digital Power power phase configuration
Going to the smaller mATX form factor we have the B450 Aorus M and B450M DS3H. The Aorus M has the same 8+3 power phase design of the larger boards and supports the same number of expansion slots, but only has one m.2 slot and heatsink and uses Gigabyte Gaming LAN. It does have the USB 3.1 Gen2 ports of the Aorus Pro boards. The B450M DS3H only has a 4+3 power phase design, uses Realtek GbE LAN, has one m.2 slot but does not come with a heatsink, and lacks the USB 3.2 Gen2 ports. All of these boards though do support four DD4 DIMMS though, which is not the case of the last one.
The B450 I Aorus Pro WiFi is the lone mini-ITX board of the bunch. Being ITX, it has only the single PCIe 3.0 x16 slot and two DDR4 slots. It also has a 4+2 IR Digital Power power phase design. Its display interfaces, for those who want to use the built-in GPUs of the Ryzen APUs, are a DisplayPort and two HDMI ports, while the other boards offered an HDMI port and DVI-D port. It does have the dual band Intel 802.11ac Wave 2 WiFi of the Aorus Pro WiFi, Intel GbE LAN, and comes with a heatsink for its m.2 slot. For USB ports though, it does differ from the others and its two USB 3.1 Gen2 ports are both Type-A.
