Because of the Zen chipsets' design limitations, USB 3.1 transmission speeds drop dramatically as circuit distance increases, forcing PC and motherboard players to add additional retimer and redriver chips or even an independent USB 3.1 IC in order for the function to work properly. This has thus increase the makers' costs.

2 - 5$. I wonder how the final retail cost will be.

AMD Zen chipset designs have already been finalized and will begin shipments at the end of the third quarter and start mass production in the fourth.

They say its a Zen chipset issue but then don't explain why... This is an issue with USB 3.1 regardless... that is why some Z170 motherboards advertise the extra hardware they have, so that your USB 3.x speeds don't drop off...

doesn't sound like something exclusive to AMD to me. I've seen this before.

Long traces have greater resist to change (capacitance and inductance) who would've guessed. This is actually why you can not have GHz signals on traces without difficulties. Doubt it will be a huge deal a normal consumer will probably not even notice it.

Digitimes, do your research before posting male cow excrements please.
if the product is AMD = it is AMD fault. Always..... /s

Intel chipset boards have problems too, mosfets get hot and thus makers need to place heatsinks on the board which costs extra. /sarcasm
