CPU Upgrade Results (3800X->5800X)

Hello all, first post, hopefully it’s in the right place…

I recently made a small upgrade to my PC, and I wanted to share the results as they might prove helpful to others.

Prior to the upgrade, my PC was as follows:

  • AMD Ryzen 7 3800X (8c/16t)
  • 2x16 DDR4-3200 CL16 (G.Skill Ripjaws V series)
  • Asus TUF Gaming X570-Plus mobo
  • Corsair MP510 960GB NVMe as a boot drive

I have now upgraded to an AMD Ryzen 7 5800X (which necessitated a massively larger air cooler and a BIOS update), but everything else in the system remains the same.

Prior to the upgrade, I created a progressively larger patch until I was getting consistent audio processing issues (“crunchies”). After the upgrade, I then took the same patch and expanded it further until I once again began getting audio issues. Samplerate and thread count (7) were identical.

Despite the 5800X having only ~20% more performance on paper, I was able to double the patch size before reaching the same level of crunchies (and even then I think the second patch still performs better). I’m very impressed by the improvement. As this thread points out, the move from two CCXs (3800X) to one CCX (5800X) is likely responsible for huge difference, due to reduced inter-core data latency.

TL;DR if you’ve got a Zen 2 CPU and you’re running out of cycles, consider a Zen 3 CPU :slight_smile:

I went from a 2700x to a 5900x, literally night and day, haven’t hit a CPU wall on anything yet.
