AMD FX-8320 versus FX-8350

I currently have a Phenom II 955 at 3.2Ghz (quad-core).
CPUboss indicates that my Phenom II would get almost exactly the same performance as an FX-8320 in single core tests. That doesn't sound possible. :s

Would an FX-8320 be a worthwhile upgrade for single-threaded games and applications, or would I need to go to an FX-8350 for a significant improvement?

  1. CPU-boss is generally quite unreliable, but it's not that far off here. There really isn't much of a difference in single-threaded performance between the Phenom II and FX CPUs.

    If you want more single-threaded performance, you should buy an Intel CPU.
  2. http://cpuboss.com/cpus/AMD-FX-8350-vs-AMD-FX-8320

    Not much difference, which ever is cheaper, other wise 8350

    These CPUs are only useful if you are using multiple cores, otherwise even a celeron could potentially rival them. If you use programs that only use a single thread, I'd recommend an Intel i5-4440.
  3. There is less than a 10% performance difference between the 8320 and 8350. And intel is the way to go for best single threaded performance/dollar.
  4. I was worried about that. :/ I actually need an AMD CPU because I need to replace my motherboard immediately (the one I have is dying), but I have an AMD CPU. That means I need to get another AM3+ motherboard, which in turn means my CPU will need to be AMD when I replace it a while later.

    Would I see significant performance increases on double or triple threaded applications with an FX-8320 over my Phenom II?

    Depending on the benchmark, they show 70% or better multi-core performance for the 8320 over your Phenom, & the single-core performance shows as 25% better. Note that I'm not talking about their generic "scores" (out of a 10.0 range), I'm talking about the listed benchmark numbers from the 3rd-parties: PassMark, CineBench, Geekbench, etc.

    The 8320 should be more than fine for you, & is much less expensive than the 8350...which, if you ever decide to overclock, is a major point since the 8320 OC'd can match the 8350 OC'd for performance.
  6. If you have a good mobo and cooler you can OC the 8320 way over 4ghz, if you dont have money for a good mobo/cooler get the 8350

    Passmark is pretty useless, and Cinebench shows a very limited difference in single-threaded performance.
