What the heck is “X3D Turbo Mode”?



If you go to Gigabyte’s website the page is broken…

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).

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…

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.

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

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

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.
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 :D

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:

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

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

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.
I have a bad feeling that this CPU could remain OOS for a year! :eek:

And dang scalpers!

AMD needs to implement some sort of fair buying system with checks and controls against abuse for these CPUs.
