Question Zen 6 Speculation Thread

[CouncilorIrissa]

I think the 1.1 is a very solid prediction. 5.7GHz>6GHz seems like a stretch though.

Not really, if it's on N2 (or even N3P). 6 GHz was the target frequency for Zen 4 in fact.

6Ghz Zen 6 with 600MB of L3 and DDR6 on 6/6 of 2026...

They cant pass that up.

6 core CCD 💀

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

You'll get stuff and a lot of frequency.
Client is out of N-1 ghetto for once!
