CPU Upgrade - worth it or not

[Mihu83]

Hi guys,

I'm wondering about cpu upgrade in my current build - for now, I have Ryzen 7 3700X paired with 64GB of ram, GTX 1070 Ti and a mix of nvme and ssd drives on a X570 mobo.

Been wondering lately about swaping 3700X with Ryzen 9 5900X... is it worth the hassel, will there been any gains in 3d applications? I know that my GPU is kind of a bottleneck at this point, but I don't have plans for changing it anytime soon, as for me it is still a solid hardware.

So, any thoughts? @AbnRanger you have some experience with Ryzens if I remember correctly?

@Carlosan Thanks, I've seen it already. Would rather hear some experience with usage inside 3DCoat, which had issues with AMD cpus.

AMD makes great CPU's, but in 3DCoat, my experience is that a comparable Intel will outperform an AMD...probably due to lingering CPU throttling in the Intel TBB (Thread Building Blocks) Library that 3DCoat uses for Multi-threading. 

I will say, though, I was able to test 3DCoat on a laptop with an AMD 4800H (8 core) CPU, a few years ago, and the performance was stellar. I had a first generation AMD ThreadRipper (1650X) and noticed that the sculpting performance was sometimes a little disappointing. But, when I tested that laptop (brand new at the time, Jan 2021), the sculpting performance was rather robust. It would be helpful to hear the feedback from artists here, who use the latest generation of AMD CPU's with 3DCoat. I switched back to Intel a few years ago (10900k) and it was a noticeable improvement over the ThreadRipper, but there have been some significant improvements to AMD CPU architecture in the last few years, so the difference could be negligible now.

Thanks for the reply. Yes, I remember there was some lawsuit against Intel, for crippling AMD CPUs.

I might try Intel CPU at some point, but not for now, as X5900 is still compatible with my AM4 mobo, so the cost will be only a fraction of what I would need to spend to make a platform change.

I guess, I'll try that 5900X and see myself if it's a worthy upgrade.
