5950X VS 5800X3D for long term

[Zarax]

Hello everyone, I'm trying to finalize my next long term build and I'm trying to understand which move would make more sense in the long run.
I'm basically building a "best of DDR4" rig as that's where the best deals seems to be had but I'm uncertain on processor choice.

If I have to look at today's gaming charts the Ryzen 5800X3D seems a no brainer as it's both cheaper and faster, however it also seems to have pretty... situational performance.
Meanwhile, the Ryzen 5950x due to sheer horsepower does offer lower performance but more flexibility and could be the better long term bet if future games will take more advantage of extra threads.

If you'd have to keep the PC for at least 6 years (but more likely 8-10), which one would you choose? Mind you, I only care about acceptable performance (60-90 fps) and I'm not going to do anything more that swapping GPUs.
To give you some context, I'm writing from a nearly decade-old i7-3770k with an RX590 so I have a pretty good tolerance for relatively low FPS.

If you want it to last 6 years, why start with a platform that is 4 years old and consider 1-2 year old CPUs.

I would stretch my budget to enjoy benefits of higher IPC and performance ceiling of latest gen.
7600X or 13600K will age better than any AM4. Maybe for budget 7600 or 7700 non-X to be released in January? Or for real end-game top gaming performance not to be beaten for at least a year, 7800X3D?

I'm already stretching my budget, if I could have afforded current gen I would have went there.

I would take this combo over any AM4 setup.
Motherboard good enough to not hold back even 7950X. Memory kit with EXPO and a decent chance to run at DDR5-6000 if need be. And a CPU that will match or beat 5800X3D in every task.

• 1 x Gigabyte B650M Gaming X AX (Socket AM5) DDR5 Micro ATX Motherboard (SKU: MB-5BG-GI) = £219.95
• 1 x AMD Ryzen 5 7600X Six Core 5.30GHz (Socket AM5) Processor - Retail (SKU: CP-3DG-AM) = £269.99
• 1 x Kingston FURY Beast EXPO 32GB (2x16GB) DDR5 PC5-44800C36 5600MHz Dual Channel Kit (KF556C36BBEK2-32) (SKU: MY-29U-KS) = £188.98

Total: £678.92 (includes delivery: £0.00)​

Please refrain from giving AM5 suggestions, while I do appreciate the spirit a 7700x build is going to cost me more than a 5950x one, which is why I'm going on AM4.

I agree with this sentiment. It wasn't the case when I bought my 5950x If I only ever intended to game then I would just go for cheaper option with more Cache, now. I like options so went with more cores/Threads.

My thoughts are why do some cpu hold there value while other decrease?

I was on a i7 3770k with same GPU now on ultra with cyberpunk and finished all ending all gigs smooth on ultra. It is partly what you are used too.

Prices on the place I use for assembly
5950x: 732€
X570 MB: 191,5€
64GB DDR4-3200: 307,5€
Total: 1231€

7700x: 536,5€
x670MB: 368,5€
64GB DDR5-5200: 410€
Total: 1315€

Basically AM5 is almost 100€ more expensive for me going down a tier.
My use case is 80% gaming 20% machine learning (hence the large amount of RAM), my i7 held up better than newer CPUs with fewer threads so that's why I'm in doubt.

If you take productivity apps which use all the cores/threads available, then the 5950X wins (and by quite a margin sometimes), but 536 euro for a 7700X is way overpriced (it is 150+ euro too high), you should be getting a 7900X for that money and when all the cores/threads are used, it consistently beats the 5950X. Though, if you spend the extra to buy into AM5, you're only buying it 50% for now, 50% for the future CPU upgrades and they will likely blow the 5950X away.

Most B650 boards have pretty strong VRMs, comparable to the X570 boards, so you can shave off 100 euro there too, but I can understand you might want plenty of M.2 slots.

Heh, that's what happens when you get in the wonderful world of having your PC built by someone else.
It's still a way better deal than buying a prebuild but it also means less flexibility and inflated prices on some parts (7950x 888€).

It is tempting going for 5950x even im thinking of it but i think if im gonna do the switch it may be cheaper to go intel 13th gen with cheapo mobo and carry my ddr4 over to it. Other option is just wait on my zen3 for a few years for am6 platform or what intel has at the time but.... That's boring...

My PC will be 10 years in January, I can hardly wait much longer...

 

[Zarax]

Yes, it is as long as you upgrade from an older AM4 chip or are budget constrained.

for 5950x money ya can get with the am5 gang with 6 or 8 core cpu. for long term as op requested its gonna be the better option.

Well, one could make a bet on 7800x3d vs 5950x for the same platform money, however in this case longevity would be an advantage if and only if you're willing to swap CPU after let's say 5 years.
