AMD Ryzen 9 3900x VS Ryzen 7 5800X

Hey all. I'm getting a new config. I already have most of the parts but I'm still hesitating on the CPU.

Here is the specs I already have:

  • Case: NZXT H510
  • Cooler: NZXT Kraken X53
  • PSU: Corsair RM750X
  • HDD: Seagate BarraCuda 1TB
  • SSD: Sabrent Rocket 1TB NVMe PCIe 4.0 (M.2)
  • Motherboard: MSI X570-A Pro
  • RAM: 2x16GB 3200MHz DRR4 Crucial Ballistix
  • GPU: RTX 3080 (jk, still waiting for availability 😭)

I'm coming from a 2013 config with GTX-760 and I5-4570 so it's quite a big upgrade here.

I'm based in France and I have 450€ of budget for my CPU. My question is, what CPU should I get ?

 

The main usages I have on my computer are:

  • Gaming (from Warzone, Watchdogs, No Man Sky, to rocket League, DBD...)
  • Working (Dev, Cybersecurity, ...)

I may try to stream next year when I will finish my engineer degree.

What I'm aiming here with this config is simple: longevity. I want this config to last 5 to 10 years.

 

So I know the Ryzen 5000 are not released yet, but I'm hesitating between

Ryzen 7 5800X:

  • 450€ at launch
  • More recent
  • Zen3
  • Less cores but better single thread performance

Or Ryzen 9 3900X:

  • cheaper (~385€ currently)
  • Zen2
  • More cores but lower single thread performance

 

I have the feeling that the Ryzen 7 5800X is the way to go because 8 cores is plenty enough, but at the same time the Ryzen 9 3900X has double the cache and since I'm aiming for longevity, more cores may be a better choice.

I will of course wait for independant review of the Ryzen 7 5800X but still, I think you can help me to make an educated choice here.


Thanks !

r9 3900x, it has those 4 extra cores, and can run them all at more or less at the same frequency, on top of being cheaper.

the only difference is that the r7 5800x "might" have better oc potential.

Go with the best CPU that fits in your budget. In this case, wait until the 5800x launches and see if you can get one. This generational leap in performance is claimed to be pretty massive especially with gaming which you should keep in mind. More cores don't really help you in the situations you will be using this computer for. 8 cores is more than enough for streaming as well as enough for the future.
