7950X3D for gaming - what is your experience?

[Zarax]

Hi, I'm split between 7800X3D and 7950X3D for my next rig.
I know that for purely gaming the former is almost always the best choice, however my workloads sometimes do make use of machine learning (and not the kind that requires GPU) so the extra cores could be useful.
I know in the past X3D cores were preferred via the xbox app, is it still like that or did AMD improve the thread detection?

For those of you who game with a 7950X3D, what has you experience been?

Thanks in advance!

just get the 7800X3D, for me no brainer, even with some additional workload from time to time.

The extra cores literally means hours saved though, we're talking about something that can take up to 3 days to complete.

To me that says you've already made up your mind, but I would too go for the 7950X3D, the extra cores and the extra core speed, youre talking double the cores and 5.7ghz boost vs 5ghz boost, with a little tweaking you'll get it to boost to 5.9ghz.

I honestly haven't, I barely made up my mind about going to AMD this round because I feel e-cores are an unnecessary complication, so I will go for a 7950X3D only if I can be reasonably certain it won't be too complicated to manage.

Then it's an absolute no-brainer you should go for the 7950x3d, but for things that take that long you should ideally try and find specific benchmarks. What is the program out of interest?

XGBoost R library, it eats RAM and cores for breakfast.
But seriously guys, does anyone here have experience with it in games? Because that's what I'll do 80% of the time...

Very happy with mine, depending on the game I was playing and what else the PC was doing i.e. watching Streams / Youtube / discord etc the 7800x3d didn't have much room left when looking at core usage. The 7950x3d has been perfect, gaming on 1 ccd and the other ccd running the other apps.

Do you still have to do the gamebar trick with games?

 

[Zarax]

The only game I've had to manually tell Windows it's a game in game bar is the closed beta for Once Human, any other game I've played is automatically detected.

So AMD fixed the thread scheduling... Very interesting, thank you!

For what it’s worth I got a 7900X3D for the extra cores and it is an excellent gaming CPU. I don’t have to mess around with cores or settings for it to give the best of both worlds.

1. Install latest motherboard BIOS
2. Install the latest official AMD chipset drivers (not the manufacturers ones)
3. Set your power profile to balanced
4. Enjoy your new CPU

In addition to above just make sure to check for AMD official chipset driver and the MS game bar updates regularly.

Why should the power profile be balanced instead of performance?

Ah, interesting... Given that I'm on an ancient i7-3770k I think I missed a lot of stuff

LOL. I just seen another post where the person says that program runs fasrter on an AMD cpu

Not that it really matters since I come from what is effectively now an ancient CPU...
