DigiTimes has some details about the shipment dates of Intel's upcoming Broadwell processors:
Intel's Core M processors codenamed Broadwell Y already entered mass shipments in September and have been widely adopted in 2-in-1 devices from vendors such as Lenovo and Asustek Computer looking to attract demand for the year-end holidays. Intel's Broadwell U series will enter mass production in January 2015 and begin mass shipments by the end of the first quarter 2015. The high-end Broadwell H series will become available in the third quarter of 2015.
Intel's 14nm Skylake architecture is expected to follow in Q3 2015 at the earliest, thereafter we can expect the 10nm Skymont.
