We’re hoping that AMD’s mainstream Zen 2 (7nm-based) processors are set to be unveiled before too long, and fresh speculation has spilled some details on a sample engineering chip.

If the information, which comes from a forum member at HardOCP (apparently with some pedigree concerning AMD rumors, according to Wccftech), is correct, then the Zen 2 (Ryzen 3rd-gen) processor has 8-cores and 16-threads with a base clock of 4GHz and boost to 4.5GHz.
