AMD Zen 4 to pack over 25 percent IPC uplift?

As always, I suggest taking these posts with a grain of salt but who doesn't like a good rumor? Chips and Cheese claims AMD's upcoming Zen 4 architecture will feature another massive performance boost. The site claims the 5nm Zen 4 architecture will have over 25 percent increase in instructions per clock (IPC). Coupled with other improvements, Zen 4 allegedly delivers over 40 percent higher performance than Zen 3.

Zen 4 is what a lot of people are waiting for, and, if the info I have is accurate, that wait will prove to be even more worth it. It is important to note that the one common thread in all Zen 4 chatter I have heard is resounding positivity. From IPC gains over 25%, a total performance gain of 40%, and even possibly (finally) 5GHz all-core thanks to the new (full node) N5 fabrication at TSMC!

Now, I can’t say what is true and what is an over-exaggeration, however I was told from a trusted source that a Genoa engineering sample (Zen 4 server chip) was 29% faster than a Milan (Zen 3) chip with the same core config at the same clocks. Factor this in with what I have heard about the possible clock gains that N5 will enable over N7 and Zen 4 sounds like it is going to be a monster of a CPU.
