I agree I think Zen 6 will tie into the release of DDR6.
However it doesn't mean we may not see some kinda of castrated version of Zen 6 for AM5 but doubting the 2025 release date.
Desktop DDR6 if it is a thing will not be like the server version, more accurately I believe it will be LPDDR6 on CAMM.There was that article semi-recently that I'm pretty sure said desktop DDR6 wouldn't be ready until 2027, so I think Zen 6 will be the last DDR5 generation.
Probably.Only LPDDR6 CAMM for desktop?
There is also CUDIMM's coming. Suspect CAMM2 (or rather CAMM3 since JEDEC wants a new toolless version) will only be for laptops.Yep, that’s the future. It’s better than DIMMs
That will extend existing DDR5 infrastructure for a while longer, but CAMM is just plain superior.There is also CUDIMM's coming. Suspect CAMM2 (or rather CAMM3 since JEDEC wants a new toolless version) will only be for laptops.
For what we’re launching today in Strix Point, both the performance core and the compact core both have the AVX cut-down [AVX-256] because they're in a heterogeneous situation, and they're in a mobile platform where area is at a premium.
In the linked article, Mike Clark indeed confirms, that they have 4 designs for Zen5 altogether, because they cut down AVX512 on mobile Zen5 and Zen5c:
An interview with AMD's Mike Clark, the Father of Zen — 'Zen Daddy' says 3nm Zen 5 is coming fast; also talks compact cores for desktop chips
AMD expands on its Zen 5 architecture.www.tomshardware.com
TH: What was the biggest challenge you encountered with Zen 5 development?
MC: It was actually dealing with two technologies [designing Zen 5 for both the 4nm and 3nm process technologies], especially a technology that the previous generation was in. And trying to do so much change, and therefore the unavoidable reality that in 4nm it's going to be [consume] more power than it's going to be in 3nm, no matter how smart we are.
But we need that flexibility in our roadmap, and it makes sense. But still that was really hard to try to control having the two technologies and the features, and a feature that looks great in 3nm not looking so great in 4nm because of the power impact of the not-as-efficient transistor and how it affects the floorplan. Normally, we do the architecture in one, and then we port on the next one, and then you have a lot of time to deal in the floor plan with the two technologies. [..] It was just really challenging. But that gives Zen 6 a lot of room to improve.

Finally the GB6 run with Strix boosting properly and it breaks the 2.9k score for the first time.

I wonder what they had to cut because of 4nm.
Anything more concrete? Is it below Zen4, below Zen1? Do you mean desktop or laptop flavor?Not hearing good news about zen 5 gaming performance atm sadly
Not just Zen 3 and 5. That's been a core part of the Zen strategy from the beginning - reusing dies. All desktop and server dies(not laptop and excluding I/O dies) share the same silicon. Laptop chips are monolithic and, while sharing the same core architecture, have a different design philosophy (mobile).I just realised - Desktop Zen 3 and Zen 5 didn't require any unique silicon just for it. IO die for Zen 3 is reused from Zen 2, and the CCD is reused from / shared with Epyc.
Same with Zen 5 borrowing io die from Desktop Zen 4 and CCD from Epyc.
I know it's obvious but I didn't realise it until now hahah
Intel also goes in this direction. If Arrow Lake SOC tile turns out fine, they can use the same one for gen after arrow lake, and borrow 6P+8E tile from mobile. (though they still have to make 8+16 tile just for desktop)
CapFrameX as a source or something else? There is zero reasons for Zen 5 to have "bad" gaming performance.Not hearing good news about zen 5 gaming performance atm sadly

AMD themselves basically confirmed that ZEN5 is bad at gaming. The Intel Comparisons were probably cherrypicked or some weird Profile for Intel ones. The "9700X is 12% faster than 5800X3D with 6000 EXPO RAM" comparison means that 9700X is 4-5% faster than 7700X. So ZEN5% is actually real in gaming.
Oh and btw Computerbase Editor just wrote this morning that there is no performance regression at all for 14900K and co when using the new profiles. Computerbase does a completely new parcours for both gaming and applications starting with ZEN5 so they habe to retest everything. He wrote, there is like a few specific situations where you can see a slightly lower score, but only if you know it. It's basically in the run to run variance region. So there's no 10 slower or something.
Interesting. Would you have a link? I didn't find anything on Computerbase site.Oh and btw Computerbase Editor just wrote this morning that there is no performance regression at all for 14900K and co when using the new profiles.

I know it’s not exactly the right comparison (since as noted before the 8945H/S, is more similar), but the 7845HX has 12 cores.finally this is impressive, almost better than 7945hx with 4 less cores and presumably less watt and thermals
R23 workload will fit in 7845HX cache, R24 won't I guess after what we have heard so far that R24 is putting more pressure on memory subsystemI know it’s not exactly the right comparison (since as noted before the 8945H/S, is more similar), but the 7845HX has 12 cores.
The average MT shows as - 13738, but some recent posts show 15500-16000.
ST is 2600-2700. So some gain in ST for the HX 370 there. But MT, eh not that impressive.
Power consumption aside, 7845HX scores around 26900 in Cinebench R23 MT. Whereas the leaks from the HX 370 have that scoring 23200 (though the single core is a little better). When considering power consumption, for the R23 score, the HX 370 should be consuming a lot less power (just how much is the important part).
What I pointed out yesterday though was that in Cinebench 2024, the HX 370, scores 1525. Whereas (adding for brevity since I didn’t mention it earlier) the 7845HX scores around 1385.
So it trades blows in those two benchmarks.
I guess my question is what happened between Cinebench R23 and 2024, for the multicore scores differential between these two chips to be so different?
Anything more concrete?

I would not bother to take what he said serious half of his posts are "Is zen5 good yet?" "So is it good yet?" "I've not recovered from the 32% hangover ." "So what's the consensus here, is zen 5 good yet?"Anything more concrete? Is it below Zen4, below Zen1? Do you mean desktop or laptop flavor?
Anyway I was wondering are decoders in Zen5 statically partitioned between SMT threads, so when SMT threads is enabled each thread ends up with 4 wide decoder and only if you disable SMT in the BIOS it might happen that both decoders will be trying to decode the same instruction stream?
Or it could be that the lower TDPs mean the chips are not boosting as high as Ryzen 7000 in games. We'll see soon enough. Looking at the core itself (as the platform is the same), there is no reason for Zen 5 to show mediocre uplift in games.My source is a VAR channel which focuses on professional applications. Ram timing might play a role but I wasn't informed of that. Performance is exactly what amd has advertised minus a few percent.
The rumored changes to boost L3 density? Maybe latency got worse and DRAM tuning plays greater roleOr it could be that the lower TDPs mean the chips are not boosting as high as Ryzen 7000 in games.
