AMD is already sampling the Threadripper 2000 series
With the announcement of the new Ryzen Pro mobility APUs, AMD also included a bit of a spoiler announcing the current state of affairs for the second gen Threadripper chips. Thus, AMD is proud to disclose that sampling for the Ryzen Threadripper 2000 series is already underway, and these are expected to ship in late Q3/early Q4 2018.
Previously leaked slides informed about the naming scheme and overall upgrades for the second gen HEDT CPUs. Just like the first gen, there will be an 8-core dubbed Threadripper 2900X, a 12-core model known as the Threadripper 2920X, as well as a top-of-the-line 16-core CPU named Threadripper 2950X. All three CPUs will be manufactured using the Zen+ 12 nm production process and will come with memory latency optimizations and higher clock speeds. The new Threadripper lineup is expected to achieve and even top the 4200/4300 MHz turbo speeds featured by the second gen Ryzen CPUs launched a few weeks ago.
If all goes according to plan, AMD could be giving a sneak preview on the gen 2 Threadrippers as early as June, possibly at Computex.
