Long time member but I have not posted in a while.

I am currently running a 7900X3D on an Asus 670E Strix mobo with 32GB RAM at 5800.
It is cooled with a 360 AIO and set to default PBO settings.
I have a 4080 Super OC as well.

The rig does everything I want it to, but like many of you here, I enjoy running new kit whenever I can.

There is not much reliable information on the 7900X3D vs 9800X3D. I went with the 7900X3D (yes I know, the hated cpu) when the price dropped to $350 on Amazon Prime Day. At the time I like the idea a solid gaming while still having productivity chops. And at the price point it made sense to me.

The 9800X3D is hard to find but I have one in hand from the nearest Micro Center. I bought it on a whim because they came into stock and I was itching to upgrade. Choice now, with a cooler head, is to sell it to a buddy for what I paid for it and keep the 7900X3D. Or swap off the chips for some extra gaming performance. Honestly my productivity needs have dropped in the last year and the rig is mostly a gaming rig with a little work and home admin stuff. But moving from 12 core/24 thread to 8/16 feels like a step back.

What would you guys do? Is the 9800X3D worth $479 less what I can ebay the 7900X3D for?

Thanks for the advice.

9800X3D, all the way. The 7900X3D is meh, at best. if you had a 7800X3D or even a 7950X3D, I'd say hold off.

I'd wait for the 99xxX3D myself, to see if they've improved the two big ones compared to the first generation, including the scheduler.

I went from a 7900X to a 9800X3D myself a little while ago and I find the non-gaming performance quite underwhelming in comparison. Whenever I do something vaguely productive I find that I'm really missing the 7900X and I strongly suspect that I'll end up with a 9950X3D.

We can make some inferences to overall performance using the TechPowerUp review of the 9800X3D.

We could assume gaming performance of your chip to be similar to, but less than, the 7950X3D. If you game at 1080P then there could be an OK bump in gaming performance on average.

If you game at higher resolutions, this performance uplift obviously decreases and essentially disappears at 4K.

We can also infer that it would perform slightly worse in other applications that leverage all cores/threads compared to the 7900X.

For TPU's application test suite, the 9800X3D is ~7% slower than the 7900X. I would probably say this would essentially be a wash because one CCD of the 7900X3D runs slower.

Screenshot

There's a decent argument in favor of the single CCD to avoid any scheduling issues at all; regardless of whatever fixes have been implemented. Everything is guaranteed to "just work" with one CCD.

If you want to upgrade "just because" then that is also fine. You will likely be gaining a little performance on average in gaming, and it will also likely be a wash on average in other applications. Any instance that simply runs better on the new architecture, or with a single CCD, is just an added bonus.

The 9800X3D is also tunable and overclockable to get even more out of it.

Plus it's MSRP...I'd say grab it and sell your 7900X3D. That makes the purchase even more justifiable.

keep it, sell the 7900 towards a 5070 + to try and harness its power

Run them both, keep the one you like the most. Pretty easy..

I would ditch the 7900X3D. It was easily the worst one of the bunch for a simple reason: As a split CCD design (1 X3D, 1 standard Zen 4), whenever you wanted to run games using the X3D CCD, you effectively had only a 6-core part, so even the 7800X3D with full 8-cores on X3D CCD would beat it.

So imo if you are using it for gaming primarily, the single CCD part will be better since you get 8 cores, no scheduling issue potential between split CCD types, and no latency penalty crossing the infinity fabric to access the 2nd CCD.

Personally I am going to wait around and see if Zen 6 brings 12-core CCD's (as is the rumor) for my next upgrade.

I went from the 7900x to a 9800x3d. I recommend you stay with the 7900x3d if you do anything other than gaming that requires higher than 8 core count. Right now you can sell the 9800x3d for probably more than you paid, whereas you'll take a serious hit on the 7900x3d and you really won't even notice any realistic difference in gaming performance.

Really great replies from everyone. Thank you all.

It seems the consensus is that there will be an obvious gaming uplift. I do game on an UWHD 3840 x 1600 (75% of 4k pixel count), so the gains may be limited a bit even with the 4080 Super.

Of note is that both users that have made the same move from the 7900x3d to the 9800x3d are not recommending it due to limited gaming gains at higher resolutions and the loss of productivity. It is likely that given my gaming resolution I fall into that camp.

If the 9800 isn’t where i go, I will probably move on the 9950X3D if the scheduler issues are reduced and ccd with 3D cache clock penalty is eliminate as rumored. But the pricing will likely be pretty scary for that beast though. Yikes.

Well, the 9800x3d is in hand. So I’m going to follow the advice from someone above and just try it. My risk is not being happy and losing some value on the resale as a used 9800x3d and when supplies are likely better down the road. The upside is that it may pair really well with my 4080 Super now and support 5000 next gen cards when they come out soon and I leve it at that… saving big money by not jumping to the 9950x3d when they drop in March.

Thanks again for the thoughts. This is the best forum that I still visit.

In terms of core affinity/scheduling, you could give ProcessLasso a shot.

Allows you to set core affinity on a per application/process basis. It is freeware, but will prompt you each time the PC restarts to purchase; only on restarts, not when resuming.

The only experience I have with it is for gaming with Intel CPUs; 12600K and 13700K. Setting D4 and Path of Exile 2 to run on P-cores only, without HT, helped with frame rates, and especially in terms of D4, made it run a whole hell of a lot smoother.

My brother recently overhauled the entire HVAC system at my place and my payment to him was a 7950X3D/MoBo/RAM. He also noted much improvement in gaming overall, and system responsiveness. He set all games to only run on the X3D CCD, and everything else on the standard.

App worked well enough that we bought it; ~$40 for 5 lifetime licenses.

If you are 8 years old and have to compensate for your small mini penis with a new CPU so that you want to brag to strangers on the Internet with some meaningless screenshots ... Yes, then you need to buy a new CPU.

Here and there you'll be 5-10% faster, but for things other than children's games you'll be 25-50% slower because of the missing cores.

In a mixed calculation, this will result in -10%/+10%, no idea how pathetically small the ego is and with which value you then calculate the new CPU nicely or badly. If you are older than 13 years old, you can pay for such a CPU out of petty cash, whether you do it then depends on your penis size, ego and IQ. The majority of benchmark disciples are brainless mongos sitting alone in the basement and only buy new stuff so that they have something to show off. Of course, the target group is also just as brainless mongos with small penises sitting alone in the basement. The very fact that you ask others whether x or y is worthwhile shows that you don't actually need anything new. Pro tip: As a player Mongo with IQ <40 ... simply switch off the FPS displays and just play. It doesn't really matter whether you have 55 or 58 FPS or 400 and 430FPS. Brainless monkeys only imagine stuff based on a display that shows them a number.

Holy cow. I hope this post doesn’t reflect the type of person you truly are. You should be careful as your jealousy and contempt for others is showing.

last I checked this is an enthusiast forum. Getting new kit and tweaking out the best performance with what you have is what this place is about, is it not?

I’ve been overclocking since I cut into my first Slot A and changed the multiplier on my Athlon 700 with the GFD. That said, I’ve been away from the hobby for a number of years. I value the advice of others that may have some experience in what I’m attempting to do. Unlike you I’m open to ideas of others.

I feel sorry for you. Being so jealous and petty. Hopefully it was just an off day for you. Peace.

If you can still return it do so, or sell it to your friend. There will still be more coming down the supply chain when the dual CCX chips arrive and you can make a better informed decision then. I've almost jumped on a 9800X3D many times since they came out but cooling off from the excitement and thinking clearly is always the best route.
