Discussion Zen 5 Discussion (EPYC Turin and Strix Point/Granite Ridge - Ryzen 8000)

[DisEnchantment]

Well, since many folks already got their hands (or at least going to get) on Zen 4 CPUs , time to discuss about Zen 5 (Zen 4 already old news )

We already got roadmaps and key technologies like AIE








Some things we already knew

• Dr. Lisa Su and Forrest Norrod already mentioned at FAD 2022 on May 9th, during Q&A that Zen 5 will come in N3 and N4/5 variants so it will be on multiple nodes.
• Mark Papermaster highlighted that it will be a grounds up architecture, Also mentioned last para here
• Mike Clark mentioned that they started to work on Zen 5 already in 2018. This means Zen 5 by the time it launches would have been under conception and planning and development for much longer than the original Zen program

For a CPU architecture launching in early 2024 in the form of Strix Point for OEM notebook refresh, tape out should be happening in the next few months already.

Intel.

If Intel isn't getting any N3 stuff from TSMC until next year it will be N3E.

It's not about the timing it's about the PDK you've picked.

While my initial response was similar to @Doug S ', if what you're saying is true, Intel is so screwed.

That's ok, they're used to this by now I'd say...

 

[adroc_thurston]

N3b is a fine node sans costs.

 

[Doug S]

It's not about the timing it's about the PDK you've picked.

And if TSMC isn't going to produce any N3B wafers once N3E comes online, then Intel would have to port their design. Which wouldn't be much of an issue, if this change in plans was done far enough ahead of time.

 

[adroc_thurston]

Who said they won't?

IT IS.
AN ENTIRELY DIFFERENT.
SET. OF PDKs.
The two nodes have nothing in common.

Hmm, so do you think Apple will maintain two different process nodes in parallel in the future? Let N3B handles high end SoC (A18 Pro & M3 series?) and N3E handles mainstream SoC ???

 

[adroc_thurston]

No they'll get off N3b asap.

Keeping this on topic, is there any reason to think AMD would have used N3/N3B for anything? I imagine they would have to cancel it or port it to N3E, causing delays.

The only candidate could be Zen 5c.

They cancelled/backported all their original N3B designs to N4P.

 

[Joe NYC]

They cancelled/backported all their original N3B designs to N4P.

Then Zen 5c is on N3E?

 

[adroc_thurston]

Then Zen 5c is on N3E?

Turin-D CCD? yea.

 

[Joe NYC]

Turin-D CCD? yea.

Nice

Why is it fine for Apple to switch to N3E in the middle of the A17's run but you seem to believe that's unthinkable for Intel?

 

[adroc_thurston]

Will they?

but you seem to believe that's unthinkable for Intel?

Apple operates like a galley full of slaves (well, most left by now), Intel doesn't.

 

[S'renne]

Will they?

Apple operates like a galley full of slaves (well, most left by now), Intel doesn't.

So basically Apple could do it since they operate on unreasonable schedules 24/7?

 

[adroc_thurston]

Yes.
Been like that for over a decade.

 

[Doug S]

Doesn't Intel have like five different design teams? They would have way more bandwidth to do this than Apple, your silly claim about galley slaves notwithstanding.

 

[adroc_thurston]

Kinda.

Oh hell no, Intel has a ton more designs in flight.

your silly claim about galley slaves notwithstanding.

It's not silly, you go to Apple to ritualistically sacrifice your friends and family for a fat paycheck.

 

[Tigerick]

Ouch, wrong info.delete

 

[Triskain]

Nice meme

Sounds good, hook me up I'm drowning in poverty here 😂

RedGamingTech put out another Zen 5 video on YouTube without any new info, so don't waste your time. I looked through it on youtubetranscript.com.
