With its new Zen architecture, AMD will be integrating the chipset in the chip itself and not the motherboard but now it appears that there are issues with the integrated USB 3.1 controller, which could raise the price of a final product.

According to a report coming from Digitimes, citing industry sources, AMD has out-sourced the design for an integrated USB 3.1 controller to ASMedia and it appears that there is an issue with bandwidth drops in USB 3.1 with increased circuit distance.

This mostly affects the front-panel USB 3.1 headers on the motherboard, which are usually located at the far edge of the motherboard.

In order to get the acceptable bandwidth, motherboard makers will have to use additional circuitry in order to get those ports to work and even dedicated USB 3.1 controllers, which will raise the overall price of the platform.

AMD has already said that Zen architecture is on track, while ASMedia has said that these are just industry rumors and that its solutions have passed all the necessary certifications.

Hopefully, AMD Zen will not face any more issues down the line and we will soon see them in action.
