AMD X370 B350 A320 X300 and B300 / A300 Compared - Only SLI for X370
AMD announced six chipsets for Ryzen based on AM4: X370, B350, A320 and the mini ITX X300, B300 and A300 with the X370 and B350 already in pre-order and availability next week.
The lads over at ComputerBase compiled an overview chart to demo the chipsets differences in a better to understand manner features wise. First off, it looks like only the X370 chipset is going to support SLI. That means the B350 would not support SLI (but does support Crossfire). THis information has been confirmed. We are not sure why but Nvidia might still be licensing SLI functionality and thus SLI supports adds a charge per sold motherboard. The B350 series is a more budget aimed one so the choice makes sense.
You'll notice there are 20 PCIe 3.0 lanes pulled from the Ryzen processor. Ryzen has 24 of them yet 4 are being used to interface with the chipset. Then depending on the chipset used it adds gen 2.0 PCIe lanes through the chipset. The X370 will add 8 lanes, B350 6 lanes and onwards. Have a peek at the chart for more details.

Each chipset will add USB ports, but the Ryzen processor also offers four native USB 3.0 ports. There is support for RAID 0/1/10 configurations as well as Overclocking support on the X370, B350 and X300 chipset. Obviously the motherboard partners can add 3rd party chips to increase USB 3.0 and so on. The four PCIe 3.0 links for X300 / B300 / A300 seem to be a bit odd, we'll try and confirm that soon.

Yes, I find it very odd, since that info doesn't appear anywhere in the slides from AMD.
Also the source of this chart states: "with X300, B300 and A300 ultimately all based on the A320, the SATA interfaces and PCIe 3.0 lanes being deleted. The PCIe 2.0 lanes are only available if NVMe with 4 × PCIe 3.0 is not available. For this, the four lanes can be output to PCIe 3.0, which come from the CPU."
Anyone else find it odd that the SFF chipsets add PCI-Express 3.0 rather then 2.0?

How about chipset comparison to Z270?

Looking at it more, if it's true, i can only imagine it's because they are gearing towards more of an APU build then a Ryzen build and that only comes with 10 PCI-Express 3.0 lanes, so the 4 PCI-express 3.0 from the chipset rounds it out a little better then 4 PCI-Express 2.0

Will all of these chipsets be able to run a PCI-e 3.0 x 4 M.2 SSD at full speed then?

Also, this just confirms what i've been saying about SFF and USB, they do indeed have more then just what the processor gives
