New budget PC: i9 12900 or Ryzen 9 5950x?

[Basshunter]

Hey guys,

I'm helping a friend to build a new PC for 3ds Max and Corona. Right now he's trying to choose between a i9 12900 or Ryzen 9 5950x.
Which one do you think would be a better and why? Any help will be highly appreciated.

5950x = noticeable multithread performance boost over 12900k
12900k = so and so single core performance boost over 5950x

In short words, your rendering/interactive rendering speed would be better with 5950x while your single core performance would be a lil worse than 12900k but nothing major as the first mentioned thing.

I would personally go for the 5950x it tends to overheat less and works better for 3d rendering out of the box. Or you can wait a month or two and get the newest 13900k (will support ddr4) which from what I hear will be a noticeable boost over the 12900k, especially in rendering.

You also have the 7950x that just released but tends to get rather hot and is only ddr5 and since you mentioned budget I would skip ddr5 all along :).

Ryzen 7950x is out now, just FYI.

He did say budget though :- ). 7950X + DDR5 + Any board = Quiet a lot of money.

In terms of performance (from most to least) :  Ryzen 7950 > i9 13900 > Ryzen 5950 > i9 12900

Thank you guys for all your answers. There's still something I quite don't understand: Why is it that some CPUs like the 12900 perform worse than 5950x when they both have the same amount of cores (16)? Same goes for the new 7950x which is supposed to perform better than 5950x but again, they both have the same mount of cores.

well, cores are not everything - each core has a frequency (GHz) and those will differ quite a bit.
Also with Intel, cores are seperated in Performance and Effiency variants, which again have different frequencies.

How much can the difference be, no? A few hundreds? And you'd be on AM5 which gives you several years for an upgrade...
I think it's worth it.
I'm thinking on building a 7950X myself but briefly checked on prices for DDR5/motherboards.

EDIT: I'm reading further comments here. Thanks. https://forum.corona-renderer.com/index.php?topic=38003.0;topicseen

A few hundreds?

But that can be a lot of money in this particular range :- ). Especially now with high inflation, super weak EUR (or CAD, GBP) to USD, recession looming.
And the saved budget can go towards GPU, which are still expensive.
