Discussion Zen 7 speculation thread

[Thunder 57]

btw is the guy incharge of the names Italian?

AMD has used city names before. And cars. And stars. Hell, even names from "The Land Before Time". Oh, and who can forget everybody's favorite, construction equipment!

"Magny Cours" was my favourite codename. Because it had many cores

 

[dangerman1337]

Verano is just a Zen 6 EPYC with a different IOD compared to Venice's. Just like Zen 3 Trento was.

Maybe higher clocks with N2X as well? Would make sense IMV

Or hell trees with HD 5000 GPUs, Cypress etc.

Big take away is that AMD seems to want to target new core to a new major node release from TSMC, which extend the cadence from 18 months in the past to realistic 24 months presently to as long as 30 months.

At the same time, Intel is on an annual cadence and releasing 2 completely distinct cores in each release.

Apple is on average 15-month cadence.

AMD seems to be headed to the extreme end of the CPU cadence. One could say extremely bad...

Thing is Intels annual cadence is useless

Maybe an issue for another thread but it isn't. Constant iteration (even if the CPU performance is stagnant) is how their client group is still doing good business. Always something new for OEMs.

LNC -> Cougar and ARL-H -> PTL-H is an improvement in terms of overall product the GPU is based though for what it has even though the only improvement is efficiency in CPU Department.

AFAIK A14 is 2028 with 1H or 2H for HVM but that's more "offical", I mean I can see A14 ramp up in 1H of 2028 for Zen 7 Epyc and Desktop & Laptop shortly as it seems AMD will be the first customer for it.

Big question is if AMD gets REALLY aggressive with Zen 7 X3D launch, like launch first with Zen 7 Desktop or be the first Desktop one and have Zen 6 be the "budget" CPUs because that 16 Core 98mm2 A14 CCD ain't be cheap.

Unknown on desktop parts. But AMD will most likely focus on Zen7 EPYC (Steamboat or whatever it's going to be).

TunnelBorer wen???

AMD has used city names before

Pretty sure this has been their server side nomenclature for a good 20 years, though the Italian only thing is only since Zen1 IIRC

K8 successor µArch family is Barcelona, Shanghai, and Istanbul - then Interlagos, Valencia, and Zurich for the Bulldozer µArch family.

Speaking of K8, funnily enough Zen6 isn't even the first time Venice was used as a codename.

Ah that was dual Istanbul MCM wasn't it?

Other than Magny Cores that seems correct. I looked it up and it looks right to me. Certain others might disagree with that source though and claim that K8 & K10 weren't things and K9 was Greyhound and something about Tunnelborer possibly using FDSOI but what do I know.

 

[DrMrLordX]

Tunnelborer possibly using FDSOI but what do I know.

Zen7 = Tunnelborer confirmed?!?!?

If Zen7 actually has 1.4nm 8C CCDs planned... 6-core Ryzen 5 lives on

It seems like AMD does not have a good, dedicated solution to 6 core desktop with Zen6. Other than re-using Medusa 1 die, which is 4+4+2 and releasing it in AM5 socket. Which, BTW, is something that OEMs might like for their commercial low end desktops.

 

[Supermecha]

K10 and earlier Bulldozer server chips were named after F1 racetracks. The platform names San Marino and Maranello were related to Ferrari/F1.

The magic trick is not shipping it and making the baseline ASP something like $399 for 8c.

 

[Joe NYC]

The magic trick is not shipping it and making the baseline ASP something like $399 for 8c.

Considering how well AM5 8 core CPUs are holding their price - $240 - $300 range for 7700x and 9700x, $399 is not outside of realm of possibilities, considering that 8 core Zen 6 would get:
- 48 MB L3
- ~6 GHz clock speed
- new IO Die with better memory support and bandwidth utilization
- some IPC increase
It should offer a solid performance uplift over 9700x

It would make no sense to go below 8 cores from the 12-core die. But there is a very wide price band between $150 and $399 that AMD will have to fill with something.

Yeah. Last gen products.

- ~6 GHz clock speed

How do I get 300MHz outta double shrink

 

[randomhero]

How do I get 300MHz outta double shrink

Ask Intel 😛

 

[Joe NYC]

How do I get 300MHz outta double shrink

It's not how much you get, but how much you lose from the top of the line 12 core CPU.

If high end 12 core CPU has 6.5 GHz boost clock, then low end garbage die may be losing 500 MHz to get to 6 GHz.

 

[adroc_thurston]

If high end 12 core CPU has 6.5 GHz boost clock, then low end garbage die may be losing 500 MHz to get to 6 GHz

How does Zen6 lose 5 bins of speed when a comparable chop chop for Zen5 (9600X) loses only 3.

 

[coercitiv]

low end garbage die may be losing 500 MHz to get to 6 GHz.

9950x 5.7Ghz
9600x 5.4Ghz

7950x 5.7Ghz
7600x 5.3Ghz

5950x 4.9Ghz
5600x 4.6Ghz

3950X 4.7Ghz
3600X 4.4Ghz

They tend to be 300Mhz apart.

Not sure I agree, produce a crap ton of 8 Core CCDs with Silverking and they'll be still quite a few 6 core CCDs.

My big question will there be enough defective Silverton CCDs that'll have half the Core and Cache count and still use X3D cache meaning you still have 192MB L3 SKUs and run the same clock speed as the full fat versions? Silverking will be "budget" Zen 7 (I mean it'll be probably be produced for a very long time since AM5 will become "budget" platform ala AM4 is right now).
