AMD has officially unveiled its current CPU roadmap around the successors to its ground-breaking Zen microarchitecture which debuted last year. The company detailed its plans well into 2020 and beyond, talking about Zen 2, 3 and even Zen 5.

Last month we reported that the company will begin sampling its upcoming Zen 2, 7nm based core this year. And it won’t be sampling just any old Zen 2 design, the company revealed that it’s going to be ready to sample enterprise server parts based on the upcoming microarchitecture, which take considerably longer development lead time compared to the consumer desktop products.
