I can see eco mode being pretty useful not for gamers or freelance productivity users but for stuff like big scale OEMs that supply corporate office settings that just want to deploy workstations for engineers to model their bathroom faucets or transformer housings or whatever on and not worry about them for years at a time. No one wants noise in their corporate office, no one's gonna open the thing and undust it twice a year, it's supposed to be quiet and just work for years, maybe your OEM workstation case design language isn't particularly airflow friendly, and less heat and therefore less required airflow are exactly what you're going to want for that setting.
By the way my own slightly aged workstation at work (I didn't pick it) uses a Xeon that's basically an i9 9900K cut in half and a Quadro that's like a GTX 1060 but with nearly 40% lower TDP despite nearly the same performance figures. Really weird setup, but apparently that's what corporates and the OEMs supplying them want. Don't question the OEM market.

Perfect for my next SFF build!
I really want power consumption figures for efficiency under work loads and at idle, otherwise the manufacturers can simply waste energy and punt the heat/bills without any accountability.
Now I use game profiles, so I can run my GPU by default with under volt/frequency and reduce heat/fan noise; while I under volt CPU with curve optimiser to gain a little efficiency and performance. So at least with AMD Adrenaline softare it's really quick & easy to go to stock or an overclock if a game benefits from high frequency performance. Adrenaline makes it easier to do than the GeForce Experience software I have used but they may have improved it since, though given the popularity of 3rd party software like Afterburner I doubt it.
It's really funny to see Gordon prove SFF is viable with his Eco mod scores in Cinebench :) So I think these kind of numbers shows my point about wasting watts to win benchmarks by negligible margins is futile and misguided.

I think I'd like the ability to tell the chip to push for 90C instead of 95C. Rather than eco mode limiting the chip on power, and stock settings limiting the chip on temp.
I imagine 90C could help longevity (even if the chip can take it long term, the fans, paste, etc will not strain as much).
but I've a habit of buying chips which are a little more powerful than what I really need, and then declocking them slightly, and watching them last like they're immortal while I save a few pennies on the power bill.

26:50 I plan on putting the 7950x in a 1U server, combining my file server, TV recording server, and transcoding server into one box.
The 12900k came close, but i need a 1U form factor, and 240w just aint going to cut it, but at 65w, the 7950x in eco mode is just the right device as it has the power to both record and transcode at the same time, and it has an iGPU for playback on devices that dont support MPEG2, H265, or AV1

I'm tired of the bias that exist in the PC gaming ecosystem
when AMD runs hot they get a free pass but when intel runs hot they are criticized, joked and bashed for it.
now power consumption has become a AMD fanboy talking point that it is almost political.
you see their are double standards when it comes to AMD and Intel, because without double standards AMD has no standards and AMD are guilty by thier own damn standards

This is one of the most interesting day-1 video I found!
I wanted some sort of confirmation that the default behavior (MORE POWER!!!!!) was just a competitive push for the top numbers, no matter what.
But in real life, we can get most of the performance while greatly reducing power consumption, if you just let the cooler head prevail. Pun intended.

Audio producers and maybe ither people want their pc to be as quiet as possible, and not everyone has the money to build a server rack and put it in a cooled cabin outside the working room.
So saying that yoy wouldn't want to make your very expensive cpu to run cool and quiet is not entirely true.

Showing the graphs showing the power consumption is cool, but rather than just talking qualitatively about them ( It looks like red has higher spikes overall ), it'd be so much more meaningful if you could also calculate the integral to give a total energy usage for each test.

the eco mode results bodes very well for upcoming EPYC server CPUs.
EPYC has to run the chiplets lower in the efficiency/power curve than desktops so I strongly suspect the eco mode results on desktop will correlate well with performance increases in EPYC.

Thanks Gordon for taking the time out to do eco mode power comparisons, this has helped put my mind at ease as every vid I have seen so far did not test the eco modes. I was concerned these modes were cop outs and fortunately it seems they are not the case.

With these results with ECO mode, now I m wondering if you can use curve optimiser while you are on this mode in order to get pretty close on stock multicore performance and little bit higher single core performance overall..

Why would small form factor buyers go for a 7950X, you might as well just go middle of the park 7600X which is aimed at efficiency like its older sibling 5600X. Would never buy 7950X just to run it in eco mode.

I am one of those mad men who will buy the 7950 and put it in ECO65W mode.
I live in the uk.
The power companies are having their way with me.
I am their front spoon.
And this is not just the tip.

Yes it does draw more power. Power is measured in Watts, basically energy per second. If I can render a scene or compile code 2x as fast while drawing 30% I actually used less energy overall.
