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

[DisEnchantment]

Speculate at will

 

[Markfw]

Silverbench P60424 Normal , X5194 Extreme
Cinebench 14242 Multicore singlepass

what model do you have for that score ? And its an ES, right ?

 

[igor_kavinski]

a CPU that excels on unoptimized, branchy code.

Instead of real 8-wide, they split it up into two 4-wides. I think they did it that way for SMT uplift so that the virtual core can boost some other branchy thread in parallel. An optimization could be that you deliberately write code that tries to stay within L2 cache and uses thread synchronization between the real and virtual core to eat its way through gobs of data.

 

[igor_kavinski]

what model do you have for that score ? And its an ES, right ?

No. It's a release laptop. An ASUS OLED with 50 TOPS AI power.

Cinebench 14242 Multicore singlepass
Cinebench 1939 Singecore singlepass

These scores are on battery with balanced profile?

No, this is the Zenbook S from Bestbuy.

It's the Ryzen 9 365.

Mains power with balanced profile.

Let me try battery

Edit: 13679 with battery

This laptop is crazy quiet, I feel like some performance is left on the table. I may poke around in the bios in a minute.

 

[Josh128]

Thanks for these. Is it even possible to lock frequency for an R23 run? Not sure what options are available for mobile. 4 GHz would be perfect to compare points/GHz to other chips.

A comparison point:

Core i5-12500 with the latest Dell BIOS update and 12 threads DDR4-3200 dual channel CL22 scores: P52719 and X4867. You carryin' around faster than desktop power in your hands in a slim form factor!

 

[StinkyPinky]

I am not sure how to lock the frequency?

Ugh. That's as fast as a 7840U. Kraken will be a total dud with 4+4. Probably will be slightly slower in both CPU and GPU compared to Phoenix.

Should be noted this is a very thin laptop with what I suspect may be a quiet fan profile (I will look in the bios in a minute). This laptop is Macbook Air thin. I suspect the thicker laptops will boost longer.

You dont know what is the power used by his device, so that s just speculations on a vaccum, it s 100% sure that a 7840U use quite more power for this score, eventually roughly 50% more power.

Edit : It should be at barely 0.5x the power for a same score as a 7840U.

IPC uplift is 17%, core count is 1.25x, so that make about 1/(1.17 x 1.25)^2.3 = 0.42x the cores power at same perf than a 7840U.

poke

I feel called out 😛

Should be noted that this is a *very* thin laptop, it's not designed to eke out every percent of performance.

Can you try Cinebench 2024?

 

[StinkyPinky]

Ok, this thing runs hot (according to the pretty basic bios). Idling in the 80s. That's a bit odd.

Well it has dual fans and Asus says 28W. It could be a bit lower than that in that specific setting, but i dont believe it when its plugged in. 7840U has 13000 something at 32.5W short burst and 28W sustained in Thinkpad T14 G4 according to Notebookcheck.

I agree with you Strix Point looks to be a minor improvement in CPU performance over HawkPoint.

Most CPUs run at 100% in BIOS so naturally it would get hot.

 

[DrMrLordX]

So if you wanted to purpose build an app to exaggerate the uplift of Zen5 over the competition, maybe branchy code could do that. While still being net slower than a comparable optimized program.

Actually what you want is something like Dr. Cutress' 3DPM v1 with its cache thrashing. It constantly dumps the pipeline. It loves SMT.

Yeah you're right. Of course. It's around 45-50 in windows.

That’s not normal. I would return it. Might be shoddy thermal paste. Even Apple fanless M chips idle at 40C.

Edit: didn’t know you were in the bios, my bad.

Igor is right, it will run hot in the bios now that I think about it. My desktop does that also. It's fine in Windows. I was certainly concerned for a minute though!

Yeah I edited my post. It’s all good.👍

I agree that I don't think it's a massive performance boost, but just pointing out this probably isn't the best device to get the full picture.

I wish the Bios was better, it's very basic. No fan profiles or anything, even in advanced mode.

I think they would have advanced UI based BIOS only in their TUF or ROG line.
