Chinese retailer JD.com has jumped the gun and listed the Ryzen 5 3500X on its website before AMD has even formally announced it. The listing confirms the tip that prolific leaker @TUM_APISAK posted last month, with AMD marketing material pitting its upcoming Zen 2 processor against the Intel Core i5-9400F. The listing reports that the Ryzen 5 3500X will clock between 3.6 and 4.1 GHz, but that its 6 cores will not support Simultaneous multithreading (SMT).
