AMD’s next generation “Zen 2” core, which is slated for release some time next year, was a largely a mystery up until earlier in the month when the company took the covers off what its CPU engineering team has been cooking in its labs and it’s quite the tasty recipe!

Zen 2, despite its name, is actually going to power the company’s 3rd generation lineup of Ryzen processors. We have already seen the company’s 2nd generation product in the form of the 2000 series Ryzen lineup. Which brought us some algorithmic power and frequency fine tuning in addition to an improved FinFET process.  With that being said, AMD does not consider 2nd generation Ryzen a redesign but rather a refinement of first generation Zen, which is expected to hold the line until 7nm is ready for prime-time next year.
