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

[DisEnchantment]

Speculate at will

 

[Timmah!]

So DozerBull. Gotcha!

Yeah. But apparently not Incavator 😛

Geekbench 6 is so unreliable, its results seem to be random. You can't trust GB 6's results under any circumstances. I've already written about it on reddit. Just look at some of the highest results in the GB6 database.

one of many examples of nonsense. According to GB6, 14900 has the same MT performance as TR with 96 cores 😀

It’s not unreliable, you just have to know what the benchmark is doing to determine how valuable its results are for each use case.

🙂

 

[Hitman928]

As you can see in these results what I gave ST also not, look at the results in the first picture. As for MT, 64 core TRs have a score higher than 96 cores. So I wonder if GB 6 can even handle 16 cores(32 threads ) processors like 7950X 9950X and not skew their results. 🙂

We have a whole thread dedicated to GB6 where this has been discussed multiple times over. You should read and post there if you want to discuss GB6.

Question - Geekbench 6 released and calibrated against Core i7-12700

https://www.geekbench.com/blog/2023/02/geekbench-6/ Weird choice of baseline CPU and even weird is that the baseline score is 2500. i7-12700 does hardly 2000 in GB5 with the fastest DDR5.

Zen 5 is about single thread performance and future upgrade path.

The future upgrade path is pretty bleak given the low-hanging fruit iteration - Zen 6 - targets 10% IPC.

Where do you have that from?

 

[SarahKerrigan]

Where do you have that from?

Same MLID roadmap that successfully predicted Zen5.

AMD core roadmap slide showing 10-15+ IPC for Zen 5 and 10% for Zen 6. Published by MLID.

 

[StefanR5R]

I really want this sort of performance in the PC world. Can you imagine a M4 level IPC x86 chip at 5.7GHz!!!!

The responsiveness be like butter.

If you want responsiveness, just fix the software.
Hardware will never win the race against software bloat.

 

[Jan Olšan]

Yeah. But apparently not Incavator 😛

Dozlubber was not so hot (or perhaps too hot, some say), but I could see myself run on Vacatinor all my life, any day.

That's the edited version, original slide just says "double digit IPC increase"

 

[Fjodor2001]

What about frequency bump on top of that due to 2/3 nm for Zen6?

 

[SarahKerrigan]

That the one that you intentionally suppressed because you thought it didn't make Zen5 look good enough, or a different one?

Adored asked my opinion on the slide and whether the 10-15% IPC claim was accurate or intentionally misleading/"sandbagging". I said I heard larger IPC gains, so he decided not to do a video on it and gave the slides to MLID.

Another reason to get Zen5 for users who need the AVX-512. Looks like AMD knows what is doing and companies like Pixar probably sent feedback to AMD and AMD delivered with Zen5.

Yeah, its common misconception that just because rendering is something suited to GPUs and there are GPU rendering solutions available, people dont use CPUs for that task anymore and therefore multi-core performance is not really even needed outside of servers.

Looks like it but it doesn’t hurt to have options.

That thread is a goldmine of information.

The quality of the GPU render is awful next to the CPU render, and it's barely touched on in that blog post, and only in passing. The time comparison was definitely not to achieve the same end result.

Definitely not, there is still a need for CPU based rendering.

 

[DaaQ]

Well, it will beat the bejeezus out of my current setup. So I am getting the 8 core V cache one, also depending on motherboards incoming.

 

[DrMrLordX]

So what's the consensus here, is zen 5 good yet?

It seems top-notch if you can take advantage of SMT with your workload. If not then maybe just kinda good.

 

[Nothingness]

And on the desktop AVX-512 too, no?

 

[DrMrLordX]

And on the desktop AVX-512 too, no?

Well yes. AVX-512 throughput should be much improved. That's a bit niche. I'd say more people could take advantage of SMT without (necessarily) having software specifically engineered for that purpose.

But that is not the selling point for zen 5 though
