While speaking with
TheStreet, Norrod gives us some critical insight into the
Zen 3 Milan EPYC processors that will be coming out in 2020. First and foremost, Norrod confirmed that Zen 3 will feature an
all-new architecture, rather than being a further refinement of
Zen 2 and Zen/Zen+ that came before it.
With that should come some nice improve in instructions per clock (IPC). AMD was able to eke out a roughly 15 percent uplift in IPC performance going from Zen/Zen+ to Zen 2, which is to be expected with the die shrink from 14nm/12nm to 7nm and evolutionary improvements to the architecture. But with a completely new architecture under the hood, coupled with
TSMC's refined 7nm+ process node, we could see an even bigger jump in performance with Zen 3.
According to Norrod, AMD will deliver "right in line with what you would expect from an entirely new architecture." He also added that he is confident in AMD's ability to "drive significant IPC gains each generation." In addition to the IPC gains, the 7nm+ node should allow AMD to ramp speeds slightly, which should result in even greater performance across the board.
