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

[DisEnchantment]

Speculate at will

 

[Saylick]

You suppose that his code uses FMA? SSE2 in x64 mode has also 16 registers, 8 limitation is only in 32bit mode.

Intel actually offers great performance monitoring programs so developer doesn't need to guess where code is bottlenecked.

He mentioned GEMM and GEMM will use FMA if available so it could use it. Since SSE2 predates x64 its hard to say if his software was compiled for x86 or x64.

But yes without profiling we can mostly throw around random guesses

The software was re-compiled to run in x64 mode, but I just double checked my email correspondence with the software vendor from 2017 so I must issue a correction: it utilizes SSE3, not SSE2. I have not reached out to them in recent history to see if they updated the underlying analysis engine to take advantage of newer vector instruction sets (i.e. AVX2), but I have not seen anything in the update logs to suggest they have.

I'm a complete noob when it comes to profiling, but I suppose it can't hurt. I'm guessing this page is a good start? https://www.intel.com/content/www/u...pc-performance-characterization-analysis.html

Probably a placeholder price, but ~$500 is somewhat realistic given the 7800 X3D launch for $450.

What the heck is “X3D Turbo Mode”?

https://twitter.com/x/status/1848182325378736139

Gigabyte X3D Turbo Mode promises up to 35% higher gaming performance on Ryzen 9000X3D — Ryzen 9000 could see up to 20% improvement

Gigabyte claims X3D Turbo Mode enables Ryzen 9000 CPUs "to achieve similar gaming performance levels as their Ryzen X3D counterparts."

did 1080p by mistake
will go again

 

[itsmydamnation]

also thats stock both 7800X3d and stock 7800XTX

Hmm..crazy if this is AMD's technology but Gigabyte is pretending like they invented it. Why would AMD let them do that?

Pretty good!

Thanks for the stock settings part.

Just one more screenshot from anyone here

Maybe they didn’t and that’s why the webpage isn’t working anymore.

it utilizes SSE3, not SSE2.

Prescott New Instructions!

Oh man, you have been robbed! Tejas would've been PERFECT for you!

My guess: 105W TDP mode for non-X3D CPUs. What's it doing to X3D, no idea, but best explanation is always OC or relaxed power limits (PBO).

As a long time lurker I feel like I can contribute a little bit to this thread.

Hi Wcctech!

 

[itsmydamnation]

that was not the number i was expecting ........ need more games to confirm....... but i did theory craft a reasonable position as to how Zen5 x3d could see more IPC uplift from the cache then zen4.

was my guess

1. clocks , can they get x3d clocks closer to base models relative to zen4?
2. can vcache allow Zen5 to stretch its legs further relative to zen4?

AMD’s Ryzen 9950X: Zen 5 on Desktop​

AMD’s desktop Zen 5 products, codenamed Granite Ridge, are the latest in the company’s line of high performance consumer offerings. Here, we’ll be looking at AMD’s Ryzen 9 9…

chipsandcheese.com
you can see Zen5 is both more data memory bound and front end latency bound then zen4 . Also zen5 is less retirement bound then then Zen4 and Zen4x3d puts noticeably more pressure on retirement.

So zen5x3d could be a banger if both the above occur.

Hi Wcctech!

@igor_kavinski should put a big ol’ “WCCFTech can kiss my a**” watermark all over those screenshots and see if they’d still write an article with em.

 

[Sunaiac]

Wow.

 

[poke01]

umm, yeah Intel is dead for gaming till mid-late 2026.

Man, this makes we wanna upgrade but I need to hold as I upgraded 4 months ago.

Edit: 400MHz OC, I wonder what the power consumption is, maybe around 180watts.

 

[Gideon]

Am I really seeing 5.6Ghz all-core clocks there?

That would make the 9950X3D a really exciting CPU to own for a software developer that also games

I know it's PBO and all ( thus prolly very good cooling coupled with heavy tuning) so the stock perf might be closer to 5.4, but it's still very impressive

 

[itsmydamnation]

62000/48000 = 1.30

we have found Zen5 30% boys ..... epic hype train return!!!!!!!!

BTW, am I blind, but i don't see what GPU he is using for the Dawntrail benchmark?

Considering the score and FSR I presume it's RX 7900XTX, but I find it strange he has blurred it out.

GPU limited
Actual score is 1. (65536 overflowing to 1)

unless its like 5090 and it has stupid high raster performance , i might put on my GPU oc's and see how much it improves score will leaving CPU stock

nup this is super heavy cpu bound , my 7900XTX with my max stable witcher 3 OC ( near 400watts ) is only pullng like 300 and max GPU utilisation is 70%

Probably some high end GPU obviously but this benchmark with this setting will make the GPU yawn from boredom

GPU be like, have at me!

CPU, all sweaty, going, I'm trying! I'm trying!

Yeah, would be interesting to know. Here there are some runs in the mid 50000-ies at 1080p with a 4090:

FINAL FANTASY XIV: Dawntrail Official Benchmark

1024x768

www.techpowerup.com

And our very own @Det0x has a score of 53072 with his absurdly tuned 9950X and RTX 3090 at 1080p:

FINAL FANTASY XIV: Dawntrail Official Benchmark

1024x768

www.techpowerup.com

I wonder what he would score with FSR + 720p?

I mean it's a super promising result, but I wouldn't mind to see a comparison to a highly tuned RTX 4090 rig, with the same settings

 

[itsmydamnation]

this is super cpu bound in some scenes im at 300fps ~ 300watts gpu with 3.0ghz clock
in other scenes im at 160 fps with 1.3ghz gpu clock but all 8 CPU cores are at 4.6-4.8ghz.
