Question Ryzen 2990WX overclocked to almost 4 Ghz: What GPU to pair with it ?

[Furi0usGe0rge]

As the title suggests, I run my Ryzen 2990WX at close to 4 GHZ (I need that many cores for other workloads), with DDR4 speeds of 3200mhz. I currently have a 1080 Ti, which is starting to feel a bit old. I was a bit surprised to see benchmarks showing this CPU can even bottleneck a 1080 Ti in some cases. Then again, those benchmarks were at stock speeds, so I assume the cores were dropping down closer to the 3.0 Ghz non-boost clock speed.

What would be a comparable CPU to my OCed 2990WX for these bottlenecking benchmarks? More to the point, what would be a reasonable GPU to pair with it?

Bottleneck calculators are ridiculous and in no way reflect reality to any appreciable degree.

Your CPU should be fine with just about any graphics card you want to pair it with. It's single core performance is about similar, just slightly less, than a 6700k but with MANY more cores, obviously. Sure, it would perform better if it had better single core performance in addition to it's many cores, but it should do well enough especially at 4Ghz, which probably takes it's single core performance to about what the 6700k has. Depending on what resolution and settings you game at, it might not even be noticeable much at all especially if you're just looking for like 60FPS gaming. If you're looking for high refresh rate gaming you could possibly run into some issues but even so you can probably offset it with configuration tweaks AND regardless, you are going to get better gameplay no matter what going from that 1080 TI to any mid-upper card from the recent generations.

What resolution do you actual game at? What sort of games do you usually play? Are you wanting an ultra settings configuration or you're ok with less than ultra settings?

Won't do any better than a 3080 roughly.

And you came to this magical conclusion, based on what?

Or do you think a 6700K can feed a 4090?

2990WX will match a 2700X in games which is roughly only good enough for a 3060 Ti max without bottlenecks.

If your using a 4K monitor absolutely a 4090 will be fine.

The higher the monitor resolution the better card you need.

One of the most insanely ignorant things I have heard in a long time.

Even at 4K a 6700K is not feeding even an RTX 4070 to full usage let alone a 4090.

Man brush up on your knowledge folks... yeesh.

No it's just the other way around your using 1080p benchmarks not 4K.
Anyhow since you have no clue what your even doing or saying you get placed on ignore.

Edit you might need to stop looking at youtube videos and join the real world.

 

[Wuwu]

Usually you back up your claims with evidence and facts^
Rather than abusing a function all so you never have to face reality.

Your edit ... still no evidence from you or the other one, this video here is above 1080P.
Even a 3080 is bottlenecked.


The claim: "It's about 6700K IPC and has many many cores, it will handle any GPU."

3080 is only 10% the performance of a 4090. And the 3080 cannot deliver it's full performance on a 6700K performing CPU, heck not on anything from the 9700K* and below either.

For the argument sake we also shoehorn in that the OP is on 4K because it suits us to pad our arguments, I allowed you that one.


Why not grab a Core 2 Duo? 8K and all that?


EDITED 3080 percentage to accommodate TPU's testing methodology, if you click RTX 3080 the 4090 then becomes 90% faster, which adds up since the 4090 is still around 40% faster than a 4080.

The 3080 is slower based upon Vram limitations also, do take in mind TPU uses a fixed schematic template across all GPU's tested... within reason, obviously a 4870 is not going to be tested in Alan Wake II in 4K.

When the OP gets back to us about the resolution, common titles and preferred settings, THEN some conversation might make sense. Until then, just isn't worth wasting time on.

I have a 4k monitor. Ideally I'd like to turn everything up to Ultra, but honestly I don't think my vision is good enough to notice the more subtle changes.

I tend to play a lot of FPS type titles. I'm into other genres, but those are the most taxing in my library.

The higher the monitor resolution the better card you need.

I notice in the benchmarks that address bottlenecking, the effect is less as resolution increases.

It seems like, to use the most extreme example, it's fair to say that at 4k I would still benefit from a 4090 over a 4080 ti, if only slightly.

While I'm so far not able to find benchmarks comparing a 4090 with a 6700k to a newer CPU, the trend I'm seeing with other comparisons.

I think it's funny how the threadripper 7975wx beats your overclocked 2990wx. If money is no object, just get the 7975wx and overclock that to 5GHz.

They are not even the same socket. You are beginning to seriously get outside your comfort zone. You honestly need to stop jumping into threads when you are not knowledgeable about the subject matter. I'm not being mean, I'm being honest.

That's fair. I know what you are saying. however, if the OP needs an upgrade in the future, which right now they don't, but they are also overclocking the chip, the 2990wx is AFAIK the highest-end chip for that socket. Any upgrade would require a new socket. I knew that they weren't the same socket, and I also know that outside of maybe some OEM threadrippers, the 2990wx is the highest end chip for the STR4 socket.

Well, it is half a decade and a few generations newer, so I'd expect it to be significantly faster. It also uses 40% more power, and runs hotter, so that helps.

If I were to upgrade to that cpu I'd need to upgrade everything except the case.

Sigh.
