Although we’ve known that AMD has long-term plans for its Ryzen Threadripper processors, we now have a few more details, thanks to recently leaked slides from a potentially legitimate internal presentation.

According to leaked slides obtained by Informatica Cero, AMD supposedly has at least three Ryzen Threadripper families planned for launch up to 2020. The information suggests that Threadripper 2nd Generation will launch this year featuring 12nm Zen+ processor cores and Precision Boost 2.0 with a focus on higher clocks.
