What is the point of 9800X3D in 4k? Isn't 9950X better at the same price?

[R-T-B]

the 9950x parks the second CCD in games, the 5950x does not.

Maybe its because I did a static overclock, but I have yet to see this.

You will still see a much tighter fps with the X3D chip - your 1% lows will be closer to the 138 fps cap. UE5 games are so badly optimized even at 4K you will feel a difference with the faster chip.

Why do you keep repeating that?

AMD Ryzen 7 9800X3D Review - The Best Gaming Processor

The Ryzen 7 9800X3D establishes AMD as the leader in gaming performance. This Zen 5-based X3D chip is not only fast, it also comes with full support for overclocking. Besides gaming, application performance is considerably improved over the 7800X3D, but that comes at a price.

www.techpowerup.com

9800X3D gives you 77.8fps at 4k (default settings).
If you're looking for a 3fps loss (74.8) you have to go all the way back to 9700X or 5950X. Even my aging 12600k manages 72.7fps. You're telling me I should upgrade for a 5fps gain?

 

[JustBenching]

So I am building a new PC for RTX 5090. I was looking for CPU.
9950X is the same price as 9800X3D right now.
What's the point of 9800X3D if I will use my PC only in 4k+?
Isn't it better to go X and have 8 extra cores for the same price?

That's a wrong dilemma. If you care about those extra cores (Mt performance) than the 9800x 3d is out of the picture anyways. I'd say if you don't care about the MT performance and you are playing at 4k you can look at the 9700x which is half the price.

Keep in mind that when I was comparing the 12900k to the 9800x 3d (with a 4090) I had to drop to below 1080p (dlss perf) to measure differences, the GPU will be a much bigger bottleneck. In any of those heavy games your 5090 will choke at 4k, in the lighter games even the 9700x will spit a lot of fps anyways.

Do you have the Xbox game bar installed? That's the component that parks cores while gaming on a 7900X3d, 7950X3D, 9900X, and 9950x.

That's with a 4090.

Fact is the CPU FPS numbers are the same for all resolutions, you just become more GPU limited the higher you go which pulls down the numbers. With an infinitely fast GPU the potential of the CPU is the same at 1080p or 4K, doesn't matter.

That's why you look at 1080p results for CPU testing, and 4K results for GPU testing.

There's also the reality where many games are CPU limited, or GPU limited. Tarkov for example doesn't care about your GPU, it's CPU and memory starved.

Guy was asking whether an X3D CPU would make sense for 4k gaming. You tell him to look at FHD numbers. Nuts.

 

[dgianstefani]

Bottom line is having a much stronger CPU is nice even at 4K, and there's no reason for a gamer to buy a dual CCD chip.

If you say so bud.

Perhaps you can point out the benefits of two CCDs for gaming to the community.

What's it like pretending CPU limited games don't exist?

It's not me saying, it's the benchmarks. Nothing to point out, in 4k you can't put a piece of paper between the two.

The OP questions was rather simple:

Benchmarks say he will gain very little from 9800X3D. Both CPUs will perform the same in games, with the 9950X giving him an advantage in other multithreaded apps.

Ah, the CPU benchmarks tested with a two year old graphics card.

I see.

 

[Frick]

Some games really like the x3d stuff. If pure gaming and that budget there's no sense to get the 9950x, but if the workload includes anything that can make use of cores I'd absolutely get the 9950x instead.

Because it's true?

You're posting an average across all games -- that's the "bill gates in a room full of nuns" problem - everyone in that room is, on average, a billionaire - but it's not the reality.

 

[harm9963]

If you have a 4K Monitor then no, don't let anyone make you overthink it to the point you're paying a premium for 0 reason... buy the most current platform you can and a CPU that makes sense for you when it comes to Windows OS performance, productivity etc.

When I think of a gaming computer I think of the GPU first.

over two years with my 4090 ,over 4 years with my 5950X CPU, never been better .

Those averages at the minimums of a cheaper x3d chip, have never been better.

No, I intentionally removed it. That does explain it.

4K Balance upscaling is not even close to 4K native , which is what I use ,plus DLAA which is more demanding .

You powershelled it out?

Do you get the 'select app for the ms-gamebar' or whatever notice? I cant get that to stop poppin up.

So you like to play at 60FPS - a that's fine.

nah, our enterprise image has it completely uninstalled. So its gone from the get go.

Yes, I do unfortunately. I just associated that link to a custom coded app that does literally nothing lol.

If you have this game , run the same settings ,lets see your results please !!

[MrBanana]

The answers is easy no?
If you just play games get the 9800x3D, if you need more cores for other types of workloads get the 9950x
Don't overthink it.

 

[Dr. Dro]

For 4K+ gaming, editing and megatasking, R9 9950X, Core Ultra 9 285K or i9-14900K. Personally, I'd go the unpopular/unconventional route and buy the U9 285K alongside a nice Z890 Apex and some 10000 MT/s CUDIMMs. Fun build.
Will be running my 5090 on the i9-13900KS (= 14900K) and Z790 Apex Encore here.

 

[phanbuey]

...U9 285K alongside a nice Z890 Apex and some 10000 MT/s CUDIMMs. Fun build.

Those are alot of large numbers. NGL that does sound pretty sweet.

@harm9963 - stuck in meetings but will run CP2077 later.

I play that game with FG off at ~160FPS-230FPS no RT @ 4k quality dlss - struggle to keep the 9800x3d feeding it in any heavy crowd scenario. FG makes this game feel mushy, no good for FPS unless you have to use it.

 

[Zazigalka]

isn't DLSS use frame gen x4 from 60 to 240 fps so the CPU is not so important?

FG/MFG isn't relevant to this discussion at all, we're comparing base fps, before any frame generation is applied.

 

[Dr. Dro]

If the experience is anywhere near as smooth as it has been with the 13900KS and Z790 Apex Encore, it will be every bit as sweet as it sounds. With my older 6800 MT/s UDIMM kit, getting it to run at 7600 with similar timings to stock was a 10 minute job... these boards are just raring to go

I think there's a lot of negativity in both sides right now, the X3D vs. no X3D conundrum (I just oppose the split CCD R9 X3Ds, they're a bad deal because ultimately Windows just wasn't designed for what AMD is pulling here, you'll see chips like the 7900X3D have tons of resources that the OS simply cannot make use of, causing it to be worse than the R7 X3Ds and even R5 X3Ds in some situations), the mass hysteria of "Intel chips that drop dead" (despite the fact that it's been patched, affected a relative minority of samples shipped and Intel extended the warranty to 5 years - not excusing them but the bad publicity was quite overwhelming and frankly, far beyond the proportion of the problem and Intel made good to their customers by replacing all affected units and extending warranties), or that the Core Ultra chips don't show massive gains over their predecessors (although they remain as tweakable as ever, iirc), biggest problem with Ultra in my opinion is the dogshit prices and availability, but it should still be reliable and fun IMO

tl;dr X3D isn't mandatory, and if you have the dough for a 5090, just build an enthusiast machine that fits your own personal needs. Buying a 5090 "just because" and then not even knowing what to pair it with... my brother, get a 5080 or 9070 XT then, and a 9800X3D... run of the mill ultra high end gaming PC will cost you a lot less and provide just as great a gaming experience. No use having a 5090 if you'll cut corners anywhere, and that's my $.02

Isn't it better to go X and have 8 extra cores for the same price?

lot of questions here that need more specific details

equal price, the 9800X3D is the clear gaming winner. For the price, the 9950X is not a good value gaming CPU. Most games will not utilize the extra cores in the way you are thinking and the 9800 offers a larger core cache in games that can utilize that. For any apps that can utilize the the extra core, you can certainly make a case for 9950x.

for 4K gaming? You may be GPU locked now but in an upgrade (or two) the 9800X3D makes more sense for gaming which is why people look at lower res benchmarks even if they game at higher res. If your CPU can't do 100 FPS at 1080p, it won't do it at 1440p or 4k either.
