German tech site Planet3DNow claims AMD is planning to launch its Socket AM4 platform in March 2016. This sparks some speculation that perhaps Zen may arrive much sooner than anticipated, but that seems unrealistic. If the rumor is true, it probably means AMD is still planning to launch 28nm Carrizo APUs on the AM4 platform, before the arrival of Zen toward the end of 2016 or early 2017.
The new AMD Zen CPU will use a new socket and also incorporate the current DDR4 capabilities and as such completely new boards have to be designed. In a routine inquiry about this, the publication got a surprising response from the manufacturer. The response: “The internal timetable foresees a March 2016 launch”. That is a lot sooner than expected.
