AMD will be releasing a Ryzern 5 3500 as well as Ryzen Pro variants of the Ryzen 5 3600, Ryzen 7 3700 and Ryzen 9 3900. A Eurasian registration database points that out.
It is not the first time that products are spotted there, it is a mandatory step to register products for import in several countries. The procs all have been listed at 65W TDP including the Ryzen 9 Pro 3900 with twelve cores. The database lists the model numbers, the number of cores and the tdp.
The Ryzen 5 3500 has six cores and a 65W TDP. This is probably a cheaper model with lower clock speed. It is not yet known when AMD will release the processors.
