Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000)

[DisEnchantment]

Speculate at will

 

[Philste]

Yes, that's called having no competition.
1T power is still up and you're probably gonna feel it.

So it's all for 1T, so 9700X might have lower MT perf than 7700X because it clocks so low at 88W compared to 142W 7700X that the IPC is completely negated?

None of the Z4 DT parts ever hit rated TDPs due to thermal limits.
142w on the 8c Raphael is a joke.
These things are tjmax-driven, like phone chips. Or Hamoa.

YIKES!

All that performance for 5mm^2 moar die area? Sign me tf up broski.

I know but down to 88W is still a big reduction if the Cores itself need a good bit more

No.

The whole thing with v/f curves is that you don't have to ride the very top.

Unless you are Intel....

AMD rode it very much for Z4.
Competition!

 

[lixlax]

If those TDP numbers are true then it confirms that Zen 5 is excellent and AMD doesn't mind leaving a few percent of performance on the table to gain efficiency. Except for the 16 core that is the flagship anyway.

The cynic in me wonders if this will widen the gap between the 9700X and 9950X in games and that will push some gamers to go for the 9950X before the x3D parts launch in 6 months or so.

If we are hearing rumors correctly, the 9950x will be better in everything than the 7950x3d or 7800x3d in gaming.

 

[Timmah!]

But what if we are not? How are we supposed to wait 3 more days to find out? :-D

A year.
Gotta wait a year.

 

[APU_Fusion]

No way I am waiting a year for 9950x3d. Sounds like 9950 and 5090 combo to boost my Office 365 productivity is in my immediate future.

 

[Timorous]

A year.
Gotta wait a year.

So the X3D parts are going to be a mid cycle refresh before Zen 6. I mean if there is no competition then there is no reason not to slow play it and get people to double dip but it does not make me happy.

Bingo.
This year is new IP, next one is derivatives and midgen kickers.
Rinse, repeat.

So not CES for X3D?

 

[adroc_thurston]

no. CES is mobile stuff.

 

[Philste]

no. CES is mobile stuff.

Wow, that's another ZEN5 product that skipped, right? Pretty sure the rumor was X3D at CES2025 for last few months.

Anyway, good thing imo. X3D is worth a geneeational uplift, so mid gen is the right spot for it to launch. ZEN4 was just early because Raptor was kinda strong in Gaming.

 

[adroc_thurston]

Hopium.
Zen4 V$ parts were only early because a comp response was necessary.

 

[poke01]

no. CES is mobile stuff.

ahh yes. My favourite Strix Halo from AMD.

 

[Joe NYC]

no. CES is mobile stuff.

2023 CES had both mobile and X3D. Hopefully a repeat in 2025.

 

[Timorous]

For gaming, especially tic-rate limited titles, Zen 4 X3D or Zen 5?

 

[adroc_thurston]

Competitive. Response.

The answer should be pretty obvious.

 

[Timorous]

The answer should be pretty obvious.

Lack of testing makes it hard. Zen 5 is throughput monster so can see it being better late game Stellaris for example. But mid game while the dataset fits in V-Cache I could see the Zen 4 being faster.

 

[adroc_thurston]

It's just a way better core.
Plain and simple.

You know the thing has something funny going on when x87 IPC is up double digits.
