Zen 3: 7nm+, design is completed, slated to launch in 2020 (Ryzen 4000 series?)
Zen 2: 7nm, launched in July 2019 (Ryzen 3000 series)
Zen+: 12nm, launched in April 2018 (Ryzen 2000 series)
Zen: 14nm, launched in February 2017 (Ryzen 1000 series)

When asked by CrimsonRayne at RedGamingTech if the Zen3 IPC gains would be in the neighborhood of 5-8 percent, the source said it would be even higher.

It surprises me they keep finding such large ipc gains...

Plus it looks like they found more frquency boosts as well...

Perhaps Intel just managed to lower our expectations after years of Skylake stagnation. There was a time when an 8% increase in IPC would be greeted with "meh", but now it's "large".

Over the past quarter century, we've managed to hit all the "low hanging fruit" in terms of process improvements, clock speed increases, and clever architectural tricks to boost performance. Squeezing more performance out of silicon is HARD now.

E.g... from the early 1970s to to the mid-1990s, microprocessor clock speeds increased by roughly a factor of 100. From the mid-1990s to the present, clock speeds have increased by roughly a factor of 20, and have barely changed at all in the past half decade.
Nostalgia isn't what it used to be.

'Nother example: between 1997 and 2001, Intel increased it's clock speeds from 333 MHz to over 1 GHz. To get an equivalent increase today over what was on the market in 2015 they would need to be pushing over 12 GHz.
