Hi all,

I'm thinking about upgrading from my current Ryzen 9 5900x to a 5950x. The rest of the system would remain the same. Would I need to install a clean OS or would that be unnecessary given that the architecture of the two CPUs is so similar?

You wouldn't need to do anything except swapping the CPU. They are the same CPU, both have 2 CCX-es with 8 cores, the 5900X just has 2 cores per CCX disabled.

CCX = core complex.

 

Might I ask why you're upgrading? Productivity tasks?

Yes, I'm currently working on an animation project and will render many shots with after effects. Adobe implemented the render multiple frames simultaneously a few months ago, which makes a better use of a higher core count.

 

Edit: also prices are low at the moment so it sounds like a good time.

Have you considered Zen4 AM5?

30% more cores for maybe a 25% uptick in performance doesn't seem like that great of a deal.

 

Unless this is literally what you do all day every day for a living, and saving a couple minutes a dozen times a day over a year means you get 3 days of your life back..

 

If you go big, I'd just get a 7950X and go whole hog. Otherwise it's kind of a waste of money in my mind.

Not really. Even if the uplift would be a lot more significant, I'm not ready to invest in a whole new platform - both financially and technically. I feel like finding a second hand 5950x and selling my 5900x is a small investment that makes more sense right now if I find a good deal.

That's precisely why I asked if it needed any extra work. If I lose a day resetting everything, the investment makes less sense

I've upgraded a 3900X to 5900X, and really it's 15 min work (mostly due to uninstalling/reinstalling cooler)

If you're in productivity stuff the upgrade makes sense, will cost you maybe $100-$150 (sell/buy used) + 15min work for 25% faster processing

A 7950X will give you +50% but would cost way much money and effort
