To quote myself from sometime last year:
Although, early days yet. This is just a leak without detail with a pinch of speculation.

I think the guys expecting 4.5ghz will be disappointed. Looking at a 4.0/4.1ghz overclock I reckon
yeah because leaks with ES chips are final product... right.
Everyones said 10%, im still maintaining 10%, im happy to be proven wrong when something official is announced, until then im not buying clickbait.
Same ^^^^ 10% is what we think and we know literally nothing yet.
This isn't that, this isn't 7nm, that's Ryzen 3, 2019.

This isn't what? People were speculating hopes of 4.5GHz+ for Zen+ previously and that was my response.

I recon 4.5Ghz, maybe a little more but no... no 5+Ghz stuff.
Well i didn't see that, the processing node this is built on is touted to be 10% faster.
The 5Ghz thing is the next one, 7nm

It came to conversation when the 2600X "leak" video came out people where trying to guess the clocks despite not knowing the difference between Zen+/Zen2 and Zen3, or whatever else AMD want to confuse the public with.
As for 7nm being a 5GHz thing, that's so far off, it's not worth even throwing numbers about.

Its based on Global Foundries public data for 7nm, what Zen 3 will be built on, as always its speculation but unless GloFo can't deliver on their promises (A possibility) its a pretty good bet.
We have waited 5 years for Intel to give us a 6 core in the mainstream, its not so bad.

I understand that, but public data based on what architecture exactly? We don't know how Zen will turn out at 7nm and how the chip's design will have changed by then. It's speculation and estimations.
Let's dial this back to today, with Zen+ which we know for a fact is just a small increment and mature Zen. Then when we get into 2019 we can see closer to the unknown leading up to the announcement from AMD.

The entire architecture will change, has changed, AMD have said its already design complete and a ground up rework.
As i have explained earlier in the thread the processing node is as much to do with how many Mhz a CPU can run at as it is the CPU its self.
The Mhz a processor can run at does also depend on the architecture, but saying AMD can't get to 5Ghz is like saying Gordan Ramsey can't cook, Mhz if nothing else is what AMD are particular good at, they still hold the record for the world's fastest CPU at 8.72Ghz and Zen 1 can under sufficient cooling run at over 5Ghz on all 8 cores, the first thing it did when launched was obliterate Intel's Cinebench Multithreaded world record, this with a CPU build on a 3Ghz Samsung process.
AMD know how to get Mhz out of their CPU's like no one else, whats limiting them now with existing Zen 1 is the 3Ghz process they are on, that will change when they get on the 5Ghz node.

I'm not saying AMD cannot run 5GHz. I'm saying we don't what it can do yet.
As for saying AMD are "good at MHz"; We're talking about a completely different architecture here, this is my point. It is unknown to us what this architecture/design is capable of currently. Nor do we know what they intend to change by the time we get there.
You would have to assume Zen 3 can't get to 5Ghz even on a 5Ghz node, given AMD's history (the purpose of my explaining it) that's unlikely, but you're right about one thing, nothing of course, is ever set in stone, so whatever man no matter how unlikely i would be stupid to say, blatantly, you're wrong, so go ahead i'm not here to change your mind.
Why do they need huge gains in IPC?
Due to better than Intel SMT their MT IPC is on par with Coffeelake and only 10% short of Intel's in single threaded, Intel's has changed little in 4 generations, i'm surprised you're so focused on being disappointing with AMD while having said nothing about Intel's 3% increments over the past 4 generations of CPU's, seriously while Intel are guilty of incrementalism AMD have in one swoop changed the game, disruptively as far as Intel are concerned and your disappointed with AMD? why hold them to vastly higher standards than Intel?
I am happy to believe they will be targeting 5.0Ghz on 7nm Ryzen 3XXX series as well as going to 6 core minimum rather than 4 core, whilst being able to support much higher frequency memory around the 4000/4200Mhz area at 64GB.
That seems like the 3800x would be a good shout to be a 12 core/24 thread 5.0GHz CPU around the £400-£450 mark in mid 2019.
This is speculation based on current known ability of Ryzen 1XXX series and the 7nm info we have seen so far. I mean we take the 40% at face value and that takes base clock from 3.6Ghz to 5.0Ghz anyways at the same power envelope and I don't see a reason to be shrinking the power envelope right now on desktop.

Unless there is an IPC change together with the small clockspeed bump(or some other fixes which improve performance),looks like I might be skipping this too for Ryzen 2(or maybe the next stepping of Coffee Lake).
