So what are current thoughts on overall IPC (throughput/MHz) increase for ST for Zen 6?

Are there still some who are going to make outlandish claims like they "invented the question mark" and that Zen 6 will be +30% ST over Zen 5?
I think the new IOD is going to help as will the larger shared cache (due to 12 core CCX). I think a few tweaks to the core itself will also contribute, and of course, support for faster memory.

Still, I am guessing squarely in the range of 10-20% including any clock speed improvements with the most likely number being 15%.

.... and then sadly, I suspect there will be an even longer dry spell until Zen 7 (I am guessing 4 years) as moving the design from N2 to A16 will likely not make that much sense .... so A14 would be the next design target I am thinking.

I'm a little late answering this question, but my philosophy is to mostly ignore rumors and just base my expectations off what has been achieved in prior generations. AMD has averaged low 20s percent performance-per-core every couple years since Zen1.

Sometimes generations that are supposed to be huge improvements fall flat, and sometimes generations that are rumored to be minor end up being surprisingly good. Zen+ had no architectural changes and it was 13% faster. Zen2 was rumored to be huge (so many people saying "low hanging fruit" and comparing it to sandy bridge), and it was only 18% faster. Then Zen3 was 21% faster. based off TPU's numbers

If Zen 5 is 5.7 GHz on N4P, is it that inconceivable that on the originally planned Zen 5 on N3 could reach the original target of 6.0 GHz?
Yes, only because we have been in the ~ 5Ghz window for quite some time. Increasing frequency beyond a certain point starts getting you exponentially higher thermals.... and failures.

More than anything else, it just hasn't been economically sound. Intel pushed the boundary and paid the price. I am relatively certain AMD isn't going to rush out and try to duplicate their mistake.

Of course, I could always be wrong .

I hope they can achieve 5.1GHz under 15 watts that would good. That would instantly make them leaders in x86 efficiency.

That also means they can cram in more cores for mobile. Its doable on N2 i think

I think that this is much more likely than the 3nm Zen 6 reaching 6Ghz! In fact, this is exactly the kind of thinking and strategy that would make a server based Zen 6 chip an enormous success.

a) it's N2
b) speed is funny (also matters)
I have heard the potential that the desktop and laptop might be N3P while the server is N2.

This is essentially how AMD is running now (N4P desktop/laptop and N3E server dense).

I could be wrong, but this seems to be how AMD rolls. Intel seems oblivious lately to costs, but AMD appears to be paying close attention to not just making chips fast, but doing so while maintaining a profit margin.

I agree with this. Currently with the 9950X 5.7GHz is only reached with 1 or 2 core or very light loads without extreme cooling. We will see what happens but I doubt boost frequency will increase and even it it did it wouldn't matter in day-to-day use situations.

I would be much more impressed if under the same cooling as Zen 5, when Zen 5 is all-core at say 5.1GHz, Zen 6 would run the same compute load at 5.3GHz. That would be a tangible improvement in frequency, not an opportunistic 1 or 2 core Goldilocks situation.

wait..... every top cpu has at least 10% free OC headroom.... why not default clock them up to 6ghz? bazinga

most client buyers dont understand cpu but everyone understand big giga hertz number. best marketing

In hindsight, it is a testament to Intel's tenacity with regard to the design focus on higher frequency that after Tejas, Intel still pushed too far with Raptor Lake.

I do believe that Intel is currently on a better strategic path with the Arrow Lake ish architecture. They are simply very late to the concepts of chiplets and high efficiency.

They still seem somewhat oblivious to the concepts of design for profit though. Arrow Lake is considerably more expensive to produce than Zen 5, but is under performance. I personally chalk this up to latency problems in the design related to the use of tiles. As a result, I also believe that Intel will overcome these problems just as AMD did in Zen3. I remain more concerned about design for profit at Intel.

I'd be satisfied to just have 16 cores at 3.5-4.0 Ghz under 65W.

Gimme gimme gimme.

Intel doesn't have a choice. For the long run it's also a war of attrition and AMD remains unchallenged
My point is that Intel needs to focus on design for profit..... and I agree, they don't have a choice OTHER than to start designing for profit or they wont exist.

Gaining (or regaining) market share at the expense of profit (as Intel was able to do when there was profit to spare) will end in bankruptcy, not Intel returning to its glory days.

AMD has been doing things right in this regard since they spun off GF. I am not saying they do EVERYTHING right, but the basic concept of design for profit seems to be a significant driving force in Zen and AMD's business model.
