Rumor: AMD planning 400-series chipsets with PCIe 3.0 connectivity
 

While AMD's Ryzen processors generally chat directly with graphics cards and NVMe storage devices over 8 GT/s PCIe 3.0 lanes, peripherals attached through existing 300-series chipsets are limited to the bandwidth offered by PCIe 2.0 lanes. The company's upcoming 400-series chipsets could bring PCIe 3.0 capabilities to all slots of future Ryzen motherboards, according to recent updates in the PCI-SIG Integrator's List.

As a refresher, AMD's Ryzen chips communicate directly with storage devices over four dedicated PCIe 3.0 lanes, with another 16 top-speed lanes set out for one or two graphics cards. Another four PCIe 3.0 lanes attach ...
