Brand new R9 5950x or used R7 5800X3D

[Toss]

5950x​

The 5950X is around 20% slower and in some games struggles to even hit 60fps on average it's fine but it still doesn't make sense to spend the same or more for it for a gaming build when two faster options for gaming exist in the same socket.

nice, which games it can't hit 60 fps on average??? I would like to test those

Witcher 3 NG Novigrad with maxed out settings.

It's in the 40s.

are you sure you are not GPU bottlenecked?

Yes with a 7950X3D it's in the 70s lol same system otherwise.

Here is with a 3090 you can see he is clearly CPU bottlnecked.

thx, will test it myself, I have same CPU but RTX 4070 Ti.
His usage seems too suspicious, loaded cores jumping all the time and too unstable. My CPU freq is fixed without any power saving garbage

Mine was similar at that time 3080ti I was seen 50% gpu usage in a lot of parts max settings 1440p DLSS quality. It's was much worse with the 4090.

I fixed and found out the reason. The reason is garbage dx12 optimisation. In DX 11 I am literally 100+ fps all the time

Correct, but that just turns it into last gen witcher and regardless a 5800X3D is going to be much faster in both scenarios and that is the whole point of this thread.

There are more games coming out with poor optimization than the other way around in 2025.

still 5950x can run any game 60+ fps any time. I think X3D could be justified for buy if 0.1% lows are more stable but not averages at 4k.
But I can't find any proof about 0.1% lows stability

People are forgetting I guess the OP has a 5600X the 5950X isn't even a worthwhile upgrade over it unless you need them threads for productivity so his best two options are a 5000X3D part or save up for a platform update. I've used all these cpus a ton both at 4k and 1440p a 5000 non X3D chip would be at the bottom of my list as a gaming cpu purchase in 2025 they're fine just not as an upgrade unless the person is coming from a 2600 to like a 5700X.

I am looking now for the most stable 0.1% lows CPU in the market, and seems old Intel Architecture was the one

Look, as soon Intel went TSMC that 0.1% gone garbage
This needs investigation. Maybe the old Intel is the stability king, just smart undervolt so it doesn't fry and call it the day.
x3d slower too.

Old Intel - 230+ fps.
9800X3D - 145+ fps
new intel 100+ fps.

3.96.. ewww.

Is that stock?

Brother nooo

no, I manually locked to 4 GHZ so it synced all the time. My CPU fan is 300 RPM silent lol.
I never got lack of performance yet with that config

Missing big time.. 4Ghz.. for single core stuff you are missing out on 1.25GHz.

I am running PBO here..

I'm not sure merely undervolting was ever a fix. As I recall the issues w/ degradation stemmed from some subsystem voltage on too high of a curve.
Post firmware fix, I might not be afraid of a 13th or 14th gen *but* I could not trust a used example. It'd have to be New or New Old Stock.

I've considered locking all-core freq on my Ryzens, myself. I know there's a LOT of "peak" performance loss, but...
I *very* much miss how "snappy" and "smooth" builds of old were. All this dynamic clocking, latency-spiking nonsense bothers me.


I can't find the article anymore but, back during the early days of Ryzen, a 'big' eSports team switched-back to Ivy Bridge builds, due to the issues w/ latency spikes and overall higher platform latencies.
I'm still hanging onto a z77 board and 3770k in the hopes of eventually building it into a point of comparison w/ newer platforms.

I have to say, my 3770K locked to a static 4700 sure feels soft compared to what I am used to..

 

[A&P211]

Go for 7700

*7700k

 

[LabRat 891]

There's been a *lot* of overall improvements to performance. That can't be denied.
For even 'pedestrian' and 'common' tasks like compression/decompression, there's absolutely no competition...

For me, the Ryzen 3000series was the point that 'the complications' with new platforms, became worth it.
Then, Ryzen 5000 was an appreciable improvement over 3000 -and, the X3D was like a whole 'nother generational leap, inside the 5000series' generation.

This newfangled dynamic technocrappery 'bothers me', yes. But, I'm not that crotchety as to not enjoy what "new" has had to offer.

 

[freeagent]

For me 3000 series was strong, but PBO was pretty junky, it didn't work like it does on old Intel or 5000 and up. I ran 3000 at static clocks.. being at XT it was ok with 4500-4600 static.

 

[tussinman]

5700x3d brand new is 500BGN (130 BGN cheaper than the second hand 5800x3D )

I personally would do that.

500BGN for a new 5700x3d is a better deal than 630/670BGN for the other 2 (with the cheaper option being used).

 

[Todestrieb]

My ram is 32GB 3600mhz ,and 5700x3d brand new is 500BGN (130 BGN cheaper than the second hand 5800x3D )

Brand new 5700X3D then. Way cheaper with minimal (a few %) performance loss, and no "is the CPU damaged?" trouble.

Missed this. Then definitely go for 5700x3d new.

Going to get it in 30min , wish me luck with that 5800x3d ,If I notice ''no-perfection'' in the chip I will send it back to the owner and go for 5700x3d

Update: Got the 5800X3D , the chip is from the picture , It have this fluctations at the soldering which seemed strange to me , but I installed it , it is 5800x3D in hwinfo and cpu-z , max temperature under stress in CPU-Z is 62-63C , what else should I check to confirm its legitimate and working propperly ? For Example how can I be sure that 3dV cache is not burnt or something if this cpu was used for mining or something like that ?

Run some stress test like CB2024 and game on it at low resolution 720p with upscaling

Here are the results of Cinebench 2024 . I took this test with 20C room ambient temp and there are aida64 extreme cache and memory test , should they be like that ? I mean L3 cache (96mb) to be lower than the L2 and L1 ?

And this is what chatgpt said about the strange soldering:


but the soldering on the IHS where meets the chip is kinda strange , not like straight and shiny but something like drops

ChatGPT said:​

That could be normal or a sign of delidding/resealing. The 5800X3D is factory soldered, so any unusual soldering marks might indicate:

1. Factory Imperfections – Not all chips have perfectly smooth soldering. Some have irregularities, but they work fine.
2. Delidded & Resoldered CPU – If someone removed the IHS (Integrated Heat Spreader) to replace the stock solder (maybe for better temps), it might not look as clean as the factory job.
3. Repasted CPU (Liquid Metal Use) – Some extreme overclockers try liquid metal under the IHS, which requires resealing it.

How to Check if Your CPU Was Delidded​

Temps Check – A delidded CPU should run cooler than normal (~10-15°C lower under load).
IHS Edges – Factory-sealed CPUs have a smooth edge, while delidded ones may have tool marks or scratches.
Performance Check – If your AIDA64, CPU-Z, and gaming FPS are fine, then it's working normally.

⚠ If You Suspect a Delid & Are Concerned​

• If temps are too high (above 85-90°C under load), repasting under the IHS might have been done poorly.
• If you bought it used, the previous owner might have delidded it for better thermals.
• If it performs normally, don’t worry about the solder appearance!

Final Verdict: If your CPU runs cool and games well, just enjoy the 5800X3D's power!

mine doesn't have scratches but the soldering is only kinda strange and on drops from one side while other sides are good.
