During yesterday's earnings call, Intel CEO Brian Krzanich revealed that his company will start shipping 10nm processors near the end of 2017. This will be limited to a lower-volume SKU, the real mass shipments of Intel's 10nm processors will follow in the first half of 2018:
We launched the powerful new Intel Core X-series processor family including a new Core i9 Extreme Edition processor, extending our performance leadership. And we'll be shipping our first 10-nanometer products near the end of the year beginning with a lower volume SKU and followed by multiple SKUs and a volume ramp in the first half of 2018.
Intel is currently sampling 10nm engineering samples to customers. Yields are described as "pretty much right in line with the forecasted ramp rates."
