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

[DisEnchantment]

Speculate at will

 

[Mahboi]

So peasants get only half the GPU of the nobles' Strix Point!

Honestly Kraken feels more like an heir to the 5600/5700g than a PHX heir.
It's not about gaming on an APU, it's about sort of kind of being able to game on an APU. The lowest cost still gaming capable ish system, if you're ok with regularly dropping to low settings, 720p and/or 30 fps.

I feel the best of both worlds would be a Kraken with 6 RDNA 3.5 WGPs, that would go hard in terms of PHX replacement. But it won't happen unless someone (Valve?) cuts down STX PT to 12 CUs and less CPU cores or we wait for Zen 6 to pull something nice out along with better uncore power draw.

Van Gogh is already 8 CU though, so it would have to be a major clock boost which is unlikely to come economically to power.

The Deck has been popular enough to warrant another semi custom chip.

We might just see a 12 CU RDNA4 design.

Yeah, an ideal Steam Deck 2 SoC would be four Zen5c with 12 RDNA4 CUs that also clock higher than Van Gogh. May need to wait for faster memory to be more mainstream though.

Wouldn't the Deck 2 iGPU be CPU limited with just four threads? Z1 Extreme has 16 threads. I mean, it could work for games custom made for the Deck 2 but typical modern games may not work great with just 4 threads.

Dense cores have SMT.

I wonder what kind of power envelope we should expect for Strix Halo.
16 Zen 5 cores and ~20 WGPs?
If N48 alone is 30 WGPs and runs around 215W, that's at least a 150W envelope even if you clock somewhat low.

A graphic card has power hungry GDDR6; if clocked lower STH shouldnt be above 100W including the CPU drive.

 

[Philste]

I thought Halo has 120W TDP? If it behaves like other Laptop CPUs this is more of a lower baseline, with more like open end power draw available for OEMs.

With 10% lower clocks for the GPU it shouldnt exceed said 120W, and that would be at 100% GPU throughput, in practice it shoulkd be around 100W, possibly more if OEMs want to crank up the perfs but that s another matter.

 

[FlameTail]

I recall the leaked TDP for Strix Halo was 125W?

120 - 125W for the top SKU with the GPU clocking at 3GHz.

That contradict your saying that X3D chips are second rate, the first manufactured dies are not forcible the most performing frequency wise, beside they launched servers parts first because that s a much more profitable market.

Nothing I said contradicts anything else I've said. Just because the dice that make it to desktop are "second rate" doesn't make them bad. They just don't test as well for EPYC. That's it. And you know this is true, and has been true for every generation of Zen except Pinnacle Ridge.

 

[Timmah!]

So, no new leaks today? I need my daily dosage of hype!

Well, two "sources" just told me that Zen 5 is actually 10% faster than Zen 6!

How do you know he knows that?

Not sure your left and right butt cheek count as sources.

 

[RnR_au]

Its on twitter... so it must be true...

He's been reading the same forum posts as the rest of us since 2017 (and before then too), that's how.

2500 ST score for Strix Halo in CB R23, which is ~20% better than the 7950X… meanwhile the MT score is ~11% better. Hmm. Strix Point iGPU clock is kinda lackluster given that PHXs iGPU already can do 2700 MHz but the TS score is alright at ~25% higher. I wish it had higher clocks to give a 50% uplift though.

 

[Rigg]

9600G 13% better CB R23 ST than 8600G. Seems a bit underwhelming.

It’s just random forum speculation as far as I can tell.

12C R9 9850S vs 12C R9 9800g 50% difference in CB nT?
12C R9 9855HS vs 12C R9 9800g 47% difference in CB nT?
Strix Point v Kraken having only 36% higher TS score despite 2x bigger IGP?
Hardly true. It's just a speculation.

Remember when the Stilts got mad and quit?
Remember when Zen 1 5Ghz ?
Remember when people thought Zen got the name from Suzzane?
Remember when Raja said "poor Volta"?
Remember when Crytek put a bunch of polygons under water and lied about the whole thing?
Remember when 3.5GB?
Remember when Nvidia had wooden screws?
Remember when AMD launched Hawaii on an aircraft carrier?
Remember when Charlie said Kepler > Tahiti?
Remember when a bunch of AMD executives took hundred of thousands pages of document before fleeing to Nvidia?
Remember when AMD stopped using automated process to design cpus?
Remember when AMD said Intel was using glue for Core 2 Duo?
Remember when Hector Ruiz ruined any future AMD might have had?
Remember when mr. leather jacket man wanted to be AMD CEO?
Remember when Intel said 10Ghz is on the horizon?

I've might have missed a few, and good god we need zen 5 news so badly

Edit: added some more

 

[soresu]

Remember when AMD said Intel was using glue for Core 2 Duo?

Remember how Intel said AMD was being ridiculous for that, and then said exactly the same thing for Zen MCM and Zen 2 chiplets?
