Question Ryzen 9 5900x vs 7900x?

[Greywolf74]

I currently have a 5900x running on the X570 chipset. I was tempted to upgrade to the 7900x or maybe even the 7950x but Im wondering if Im just throwing big money at a minimal performance increase for a gaming machine. I mean I know that benchmarks will obviously be better but Im talking how much real world performance difference will I see? Im assuming its probably not that much even on some of the newest titles. Thoughts?

Follow up question, Is there an Intel CPU that would be a better upgrade if I did upgrade?

In cinebench r23 multicore, the 5900x scores 21878 pts. The 7900x scores 29306, and the 7950x scores 38657. I understand that this is a synthetic test and not indicative of real-world performance, but it at least gives you an idea. the 7900x outperforms the 5900x by about 25%., and the 7950x outperforms it by 44%

Also you may want to get a new PSU as your current one is probably reaching the end of it's life and you don't want it to kill other components.

Upgrading your cpu to a 7900X or 7950X will require more than a processor replacement.
It will require a AM5 motherboard, and that will require DDR5 ram.
For a pure gaming pc, the X3D suffix processors have a good following.
Possibly, the 5800X3D might be good if Games are the only thing you do.
But for anything else, X3D performs worse than the underlying base chip.
Gaming performance is primarily determined by the single thread performance of the processor.
Unless you are a heavy multiplayer gamer, most cpu activity will be on the first 8 threads.
Run the cpu-Z bench on your 5900X. You should see a score like 668:

CPU-Z Benchmark for AMD Ryzen 9 5900X (1T) - CPU-Z VALIDATOR

Best CPU performance - 64-bit - November 2023

7950x would be 767.

You asked about Intel.
A I9-14900K would score 967. That is what I get on my 14900K using ddr4 ram.
I only need a noctua nh-d15s for a cooler.
14th gen heat issues are a myth:

You never menton what kind of games you like, but in general you will be most likely just just throwing big money for close to nothing, or nothing at all.

If you game at 1440p or higher (perhaps you use some kind of multi-monitor setup for gaming, would love to try that for my sim trucking games) the GPU will have a more noticeable impact on perfomance than the CPU.

And yes I agree with geofelt, the Ryzen 7 5800X3D is a beast for most gaming scenarios, beating even many of the newest and expensive cpus from AMD and Intel.

I would wait or sell this whole machine and build a new one. AM4 boards can't upgrade to AM5 CPU.

So your looking at new CPU, new MB, new RAM at the MIN.

I went from a 3900x to a 7900x, I do some light gaming, productivity, and photo editing. For me it was worth the upgrade, not night and day, but very noticeable on tasks and gaming.
