Question TR 24 Core 3960X, 32 Core 3970X: 280W? (16 Core downgrade)

[Kedas]

Buying an 24core on TRX40 and turning it in an 16 core to drop power is probably a waste of money, but can it be done? What would the power and performance be compared to an 16 core 3950X on AM4?
I assume the gamer mode setting would take care of less active cores.

Any guesses on cooling 280W with an air cooler? 250W was just acceptable.

The only settings I need from AMD for TR is enter your max power (Watt) and enter the max number of cores to be used, on the fly if possible, then I'm happy.

I wonder how good these will be for gaming? I don't need 24 Cores, but if they can clock to the moon...also 4 channel memory is nice.

Linus's review with the blurred out charts had them slightly below Ryzen 3k at stock. Very slightly.

The full reviews are in an hour and a half though, so not long to go.

The review I saw says it beats the 9900x all the time. GAMES

I think if Intel wanted to try to compete with this they'd have to send out waves of coders and convert everything to avx512

AMD 3960X 3970X do seem to drop for 4K in games compared to 3950X I assume that will be similar for VR.
I will wait a bit maybe there is some tweaking that can be done to fix that.
Since it's not really made for games I don't think that will be their first priority to improve on.

So makes me think of splitting my budget for an 3950X now with 2080 Super that can run more or less silent on Windows with Linux VM, not a simulation beast but still powerfull and then buy a linux server Threadripper Zen3 next year in another room that can be very noisy.

Then just turn the power down in Ryzen master. Or let it run stock with whatever cooling you have, it will throttle so it won't burn up and give you the best performance you can get with your existing cooling. Just let it do it job, no need to mess with it.

This seems like the best option. Chances are you won't be using all 24 cores most of the time anyway? Perhaps you will, but limiting the power in software will make the most out of the situation, you probably won't lose anything at low core counts in terms of frequency, and only lose a bit at highly threaded workloads. Seems like it's the answer...

Which review is that, please? @Markfw

It was a video, and I stopped watching it, at which point it was not winning near as many games, so I retract that.

But all 3 CPU's, the 3950x, 3960x and the 3970x were just stomping the 10980xe all over the place. It was a pitiful showing for the New Intel HEDT line, including the 3950x beating it more than half the time at HEDT tasks. A desktop chip no less, that is less expensive !

This is an interesting article of the power setting of the 32 core TR 3970X

Threadripper 3000 mit 180 Watt TDP im Test

Der Threadripper 3970X mit 32 Kernen ist extrem schnell. Daran ändert sich auch nichts, wenn die TDP nur 180 statt 280 Watt beträgt.

As mentioned before it's not because it has no ECO-mode support that you can't change the TDP setting.

If you make the 3970X an 180W version (instead of 280W) you only lose 10% and you can use air cooling. (10% is almost like an 29 core)

Nah i highly doubt if ur getting one of these guys its definitely not for gaming.

The gamer wants higher processor clocks after 6 cores.
The gamer also doesn't like HEDT unless its a HEDT gamer which has its own rules.

The processor will only draw what is required.
If your worried about the extra heat, i honestly say its very moot, can easily be mitigated by downvolting, rather then disabling cores.

The article also talks about using lower RAM frequency for reducing idle power usage. Using DDR4-2133 instead DDR4-3200 essentially halves the power the uncore consumes. That change very likely makes the chip less fitting for games though.

Why not enable eco-mode? It drops power draw to 140w iirc. Ironically, the 3970x in eco-mode still spanked the 10980XE.

The AMD Ryzen Threadripper 3970X CPU has been tested under ECO mode, revealing it to be an absolutely efficient monster of a chip, beating the 165W Core i9-10980XE at 140W.
