However, if AMD follows recent norms, it could release them next month. Looking back at Threadripper's history, we can recognize a fairly consistent pattern. AMD launched the first-and second-generation Threadripper processors in August 2017 and 2018, respectively. There's a good chance AMD could continue that trend.
On the other hand, the Ryzen 3000-series desktop processors launched a few months later in the year than their 1000 and 2000-series counterparts. The first generation Ryzen processors launched in March and April of 2017, with Threadripper coming several months later in August. The second generation came in April of 2018, with some Threadripper processors coming in August, and others in October. Third generation Ryzen didn't come until July, so if Threadripper again comes several months after the AM4 parts, we might potentially be looking at a release sometime around November.
Plus, I can't see AMD launching their as-yet unannounced Threadripper processors prior to launching their already announced 3950X for the AM4 platform, which is set to come out in September. And perhaps most worth considering, AMD hasn't even launched their Epyc 2 server processors yet, and it seems almost certain that those will come before Threadripper, seeing as Threadripper is pretty much just a cut-down Epyc. Epyc previously launched a couple months after the AM4 processors, and a couple months before Threadripper. AMD announced that Epyc would be coming in the 3rd quarter, but hasn't said anything about a release window for Threadripper, meaning we are probably looking at a release closer to the end of the year, in the 4th quarter. An August release seems rather unlikely.
