I've been looking to change my CPU/MB etc for a while but haven't got around to it.

So for gaming (using with an Nvidia 4090) what would be my best choice, an Intel i9 13900KS or AMD Ryzen 7950X3D? my initial thought is the Ryzen.

I've listed these as they appear to be the current top of the line.

For only gaming? Neither.

Mainly yes as I use a Mac for video/photo editing etc and wouldn't change from that.

Why would the 7800X3D be better, because of the 8 cores? and if so how much of that is game specific i.e. would newer games take advantage of more?

The 7950X3D doesn't have the cache across the entire CPU, only one CCD, the 7800X3D doesn't have the additional cores to begin with.

I suspect you won't be using the 7950X3D anymore when that's the case.

I'd go for the 7950X3D. If you like to run some background apps while gaming, having >8 cores is a sensible decision. I've tested both, the 7950X3D does much better in things like Cyberpunk at 4k with RT on.

Only if your budget can swallow it though, else get a 7800X3D.

Cheers, I have the budget and I'd rather buy something that gives me more options although it will be pretty much just gaming.

As long as the 7950X3D isn't noticeably "worse" than the 7800X3D then I'd rather get the 7950. It will be used with a 4090 and I know a few things now where my CPU is holding back the GPU a bit.

The 7950X3D is the faster chip in every scenario. It’s absolutely the highest performance gaming CPU and will tap out any graphics card on the market.

I've tested both with a 4090 Strix. No circumstances where the 7950x3D was worse. Just a couple of games where the 7950x3D does push ahead, such as Cyberpunk 2077. Again this is 4k with RT enabled.

I run a new install of W11 (don't let my install get > 6 months old, before format/reinstall of latest W11 build) with no bloatware. Just a couple of background apps, such as spotify, youtube, discord, telegram, monitoring software.

Excellent and thanks for the info, I’ll be using the 4090 strix too so this sounds perfect.
 
I would go for the 7950X3D I have one with a 4090. I wouldn't listen to those especially YouTube videos that say you must overclock it or use Curve optimizer for the 7950X3D to get the most out of it otherwise get the 7800X3D. I haven't overclocked or touched the 7950X3D its at stock just run expo on the ram and everything works perfect and the performance is very good on every game. The I9 13900KS great winter build for the colder nights coming in turn heating off won't be needed :D

Even if the CPUs were equal, the Ryzen is the first CPU on the AM5 socket, so you'll have at least 1 more generation of CPU you can upgrade to without changing motherboard, maybe 2 generations. The 13900K is the last CPU of consequence on its socket, so if you want a meaningful upgrade it's a new platform.

Just another consideration.
 
7950x3d, or 7800x3d if you're lazy.
With the 7950x3D, you can use process lasso to set it so that your games run exclusively on the CCD with the extra cache. The game will run as if it were on a 7800x3d basically, then you can have the other 8 cores process anything you have running in the background. Plus for games that do benefits from more than 8 cores you can just run it at full tilt on both ccds
 
Also, AMD's platform is superior, and you have the possibility of upgrading to Zen 5-3D in the future, which should bring a significant performance boost. It doesn't make sense to go with Intel until they offer something new like Arrow Lake
