As noted in an above post, others hypothesize (based on limited information) that AMD will skip the 10nm node entirely and go straight to 7nm. That makes sense because 10nm may not be that much faster than 14nm -- and some folks (like gamers) just want speed.
Some think 7nm will be the end of the line for downsizing silicon circuits -- and may be hard to do. If AMD succeeds at 7nm first, their CPUs might surpass Intel (for the second time this century).
This is speculation and guessing in 2016. But, it does show that big increases in CPU and GPU performance are less likely in the near term. Thus, our current upgrades to 14/16nm CPU and GPU may last a few years as the 10nm node may not be "significantly" faster and may be later than planned -- and 7nm may be much later than originally expected -- these are upgrade cost/benefit considerations for those of us AMD fans upgrading early next year (Zen CPU and Vega GPU).
