According to latest rumors, the upcoming AMD Zen 3 Ryzen Threadripper 5000 series (Codename: Chagall) is expected to be launched in August 2021. The new Threadripper 5000 series is expected to be compatible with current TRX40 motherboards.
The last Threadripper series was introduced in July 2020 – those were AMD’s new Threadripper PRO series which only made its way to the DIY market last month. However, the last non-PRO series was launched in November 2019, which means AMD has not updated its HEDT lineup for nearly 16 months.
