AMD Ryzen Threadripper 2990WX up to 4.1 GHz Today we have a CPU-Z screengrab showing Ryzen Threadripper 2990WX processor running on MSI's X399 MEG Creation, which was first showcased at Computex. A source, which provided the material, claims that chip shown in the photograph was provided by AMD (it is probably safe to assume this is a review sample or production sample provided to motherboard makers). According to the source the screenshot showcases Ryzen Threadripper 2990WX boosting up to 4.1 GHz (Precision Boost mode). We are yet in the process of confirming what W stands for in the model name.
