5800X3D or 5900X?

So the 5800X3D is £349 and the 5900X is £10 more. Which one do you go for?

I just see PC components getting more expensive so looking to drop one of these CPU's into my rig and be done with upgrading for a good couple of years, whilst pricing and availability is good.

I can't see the 5900X dropping in price much more if the historical 3900X pricing is anything to go by.

Part of my is swaying towards the 5900X. 12 cores and 24 threads. Complete overkill for my needs now but I'm not looking to change for a while, so should theoretically last longer.

However, I'm getting back into gaming and that extra cache in 5800X3D looks like it definitely helps with FPS, especially the 1% low (depending on resolution and game). However, will future games and their engines benefit more from the extra cache of the 5800X3D? Or will the extra cores of the 5900X be of greater benefit?

For reference, I' moving from a 3600X and GPU is a 3700ti.

Depends on what you use your PC for. If it's gaming get the 3D model for sure but if you use it for work and you can use the extra cores then the 12 core is probably the way to go (time equals money after all).
 
Pc components get outdated very quickly so I wouldn't be too bothered. Used prices will always come down.

Its not like buying a used car or a house.

I'd say the former is far more likely than the latter, within the lifetime of this system. If you play one of the few games that makes decent use of more cores, you'd probably know already.
 
Think I'm going to wait to see what deals Black Friday brings and pull the trigger.

I'm leaning towards the 5800X3D as that would easily handle my productivity needs (I don't do anything taxing) but would I would see the benefit in gaming (which I'm slowly getting back in to).
 
Waiting a little longer may be a good idea, AMD have apparently dropped the X3D slightly further to $329 in the US so deals are likely. I switched one from a 5900X and the difference is very noticeable in a few games I play (almost none in others, but that's expected).
 
Just came on to ask a similar question lol.
Similar to you, my main PC use case is gaming but I also use it for work (nothing too intense - Jira, Figma, Chrome, Miro etc).

The 5800X3D seems like a no brainer but can't but feel like the extra cores on a 5900/5950X would be better future proof my system.

1st, 2nd, 3rd gen Ryzen and 8th - 13th gen says that fewer faster cores are better for games than many slower cores, unless you have fewer cores than the game requires. It's a bit like memory, if you have enough memory then speed matters, if you don't then the game just runs like ****.

If your productivity tasks use the cores in a meaningful way and you spend a lot of time waiting for tasks to complete, then I'd buy the 5900/5950X, no doubt about that, but lesson of the past (if it repeats) is that they won't age better than the 5800X3D, before all the cores are too slow. An example of that is how the 4 core 12100/12100F smokes a Ryzen 1700 in games (8 core) and keeps pace with a (6 core) Ryzen 5 3600 or i5-10600.

Yeh fair point - I think like the OP I'm best waiting for a good deal on a 5800X3D. I don't think I'll use the extra cores TBH, I just thought it might be safer for the future as I'll likely keep it for 5 years.

I would simply ask the question, will I spent more time gaming or more time running apps that can benefit from extra cores?
As someone mentioned, you'd probably know already if you needed more cores.

I have a 5900X but as a gamer, if I was buying today I'd probably get the 5800X3D.

That said, In the past I faced a similar conundrum, 2700X or 3600. I went 2700X in the end for the extra cores even though the 3600 has better IPC and hence lightly threaded performance.
 
Both offer really good single and multi core performance across many workloads. I’d personally lean toward the 5900X as Intel have moved the i5 to 14 cores and increasing core count looks to be Intel’s only strategy and the direction of the desktop CPU in general.
 
It depends on what games you are running,but in a game such as Fallout 4,the Ryzen 7 5800X3D is massively faster than the normal Zen3 CPUs:

Background A few of us still play some of the old Creation Engine based games such as Fallout 4. Annoyingly a lot of reviewers don't seem to test older games anymore,and these generally benefit the most from better single threaded performance,faster memory speeds,etc. Fallout 4 tends to be...
