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

[DisEnchantment]

Speculate at will

 

[Hitman928]

AMD's Zen 5 chips pack in 8.315 billion transistors per compute die, a 28% increase in density

Something it did not do earlier.

www.tomshardware.com

28% is incredible.

That's like a full node shrink worth of density gain.

Physical Design magic?

The core grew significantly but they were able to shrink the L3 to compensate. How they were able to do so is unknown right now.

 

[Hail The Brain Slug]

What's the ST score at 5.65 and 5.7?

Hard to know if the difference was membw or clocks.

Stock/JEDEC: 120
6400/2133 EXPO tuned: 126

I thought EXPO was for RAM overclocking only? It affects ST boosts?

Can't tell you why it's behaving this way. My only thought is maybe it's not boosting higher since it's bound by the slower memory config somehow. The performance difference is certainly a lot larger than a 50MHz clock/effective clock difference.

 

[StefanR5R]

Note that the figure of 8.315 B transistors is not from a public statement from AMD, but something which Hardwareluxx wrote they had heard unofficially.

Stock/JEDEC: 120

The ST perf gain of the ES seems to be in line with the average IPC % uplift of Zen 5.

143Pts and my hard-on gone again.

Still no word about that "ladder" cache, huh? I guess we'll just have to wait for either the launch date to get more info, or worst-case Hot Chips in August.

Oh, the unbearable agony of going through all the screenshots! I hope he didn't end up in hospital. Real journalism is so hard these days!

Unlikely, because HWInfo has reported CCLK limit of 5650 mhz in cbr24 st.

 

[biostud]

No offense to 5950X owners but that's so ancient now

Then the 5900XT

lol your post have been feeding so many of these sites I hope they are cutting you a cheque or some stock options

 

[Josh128]

Then the 5900XT

Thats what Im rocking...

 

[igor_kavinski]

Thats what Im rocking...

OMG! I've got a LONG list of benchmarks for you!

 

[igor_kavinski]

Nah. I'm no.9 which means that whatever I do, I remain poor while everyone else around me gets rich!

 

[biostud]

Thats what Im rocking...

How did you get it?

 

[Josh128]

FALSE ALARM!!! I read that wrong, lol. I have 5900X, not 5900XT. Sorry bro's. Nothing to see here.

Pretty impressive it can hit 11.4 GHz at only 40 W...

 

[Josh128]

143Pts and my hard-on gone again.

Not impressed?

 

[Hemu2K]

I get 139 ST @ stock clocks on 14900KF. 143 at 5.7GHz sounds really good!

Does your score change with ram speed?

 

[Hemu2K]

Does your score change with ram speed?

I suppose it does a little? R23 does not sure about r24, my ram was at XMP 2 8000

 

[Josh128]

R15 through R23 doesnt scale with RAM speed at all. Its why the 9950X ES leaker ran his R23 at 4800MT/s. Actually helps the score a tiny bit by feeding less power to memory, thus having more to give to CPU.

I think R24 does a little bit, probably no more than 2% - 3%.

 

[gaav87]

Not impressed?

No. I anticipated max OC -30CO ST score not ~Stock
I guess il degrade that 9700X very fast trying 6Ghz like i degraded my 5600x 4years ago only took me 45days of running ~4.9ghz and 2100fclk 1.15vsoc for it to degrade. Then it needed 1.464V for 4.85G and could only do 2000fclk. Thank god 5800x3d released as by the end it could only do 4.65G and 2000fclk started giving whea's.

While my ST only saw a 120->126 score going from jedec 4800 to fast tuned ram, MT sees a much larger gain. I'll run it real quick for reference.

4800 JEDEC - 1,950
6400 Tuned - 2,280 2,190

edit: wrong MT score from memory, 2,280 was probably with PBO+CO

i was spot on. Nice work by AMD for an x86 CPU

Not impressed?

I mean Apple does up to 144 at 4.06GHz on the M3 series.

 

[Josh128]

^^ Interesting.

Igor what RAM config was used for the ES R24 run? I dont see it on the HWinfo screen.
