AMD FX-8320E AM3+ Processor Performance Review

CINEBENCH R15

Maxon CINEBENCH is a real-world test suite that assesses the computer’s performance capabilities. CINEBENCH is based on Maxon’s award-winning animation software, Cinema 4D, which is used extensively by studios and production houses worldwide for 3D content creation. Maxon software has been used in blockbuster movies such as Spider-ManStar Wars,The Chronicles of Narnia, and many more. CINEBENCH Release 11.5 includes the ability to more accurately test the industry’s latest hardware, including systems with up to 64 processor threads, and the testing environment better reflects the expectations of today’s production demands. A more streamlined interface makes testing systems and reading results incredibly straightforward.

The CINEBENCH R11.5 test scenario comprises three tests: an OpenGL-based test that models a simple car chase (which I didn’t use for this test, since the graphics card performs most of the rendering work, and I’m testing the CPU), and single-core and multi-core versions of a CPU-bound computation using all of a system’s processing power to render a photo-realistic 3D scene, “No Keyframes”, the viral animation by AixSponza. This scene makes use of various algorithms to stress all available processor cores, and all rendering is performed by the CPU: the graphics card is not involved except as a display device. The multi-core version of the rendering benchmark uses as many cores as the processor has, including the “virtual cores” in processors that support Hyper-Threading. The resulting “CineMark” is a dimensionless number only useful for comparisons with results generated from the same version of CINEBENCH.

The first benchmark renders the scene using only a single core. Overclocking the FX-8320E gets us another 10% or so in this test, but the Intel chip is half again as fast simply based on its superior core architecture.

The multi-core rendering test, though, shows that cores count…and they count for a lot. The Core i3-4360 score more than doubles (the result of Hyper-Threading), but it simply can’t compete with the 8 real cores of the AMD FX CPUs.

The OpenGL portion of CineBench produces a surprise: the Intel CPU wins decisively. We see nice result scaling with the overclocking of the AMD FX CPUs, but this is obviously not a test that can make use of multiple cores.

Let’s start the gaming-oriented testing with Unigine Heaven 4.0

    Gaming performance is changing… I picked up a G3258, Great little CPU with performance greater than say the i5 750(ish) overall. So nothing to sneeze at and if you overclock can easily surpass stock i5s. Problem?

    Well, a few of the newest games can’t be run on it (think Dragon Age Inquisition) as they require 4 cores. So what are we left with? On the cheaper side this or say the 860K. Suddenly those cheaper AMD Quads are looking a whole helluva lot more attractive and as you said your not likely to see to much difference. Fast is still fast just not as fast as some. I’ve always maintained though that for “most” your not going to notice much of a difference is most tasks provided other areas are relatively equal.

      I’ve never heard of a game that requires four cores; generally, a program just spawns threads and lets the OS and CPU sort out which resources will handle them. Windows has dozens of threads running when you’ve just booted and are sitting there (actually, I just checked, and Task Manager says I have 65 processes going in this case). Most of these threads are low priority, and it could certainly be the case that some modern games would run better with four cores, but they should run, if poorly, with dual cores or even a single core.

      So, as you point out, AMD’s lower cost multi-core chips may well be better for some of these games than a “faster” Intel CPU.

        Hi David, So sorry for the late reply. I never heard of it either till recently.. Kind of floored me actually since I’ve built a few budget machines for others that will certainly complain if they land up buying that game (one other to.. can’t remember it’s name) Basically what happens is both cores go to 100% and just sit there not allowing you to play.

    I would have been more impressed if AMD had die shrunk this CPU to 22nm instead of just reducing the clock speed thus the TDP from 125 to 95 well big whoop AMD as soon as you clock it the same as an FX8320 (3500MHz) it’s using the same 125W

      Well, it’s up to GlobalFoundries to get their process size down. It’s a non-trivial thing, you know, which is probably why I don’t know of any company other than Intel that’s managed it.

      I agree the “E” thing seems kinda silly.

    It took 8 cores to do it but they finally beat an i5 whether that’s good or bad I don’t really know, but hey still cheaper than an Intel processor I’m not complaining I bought one as well.

    Hi, I picked up an interesting but odd 8320E , purchased it for 132 CAD , came sealed in an amd box with fan which is a pretty good price, Everywhere I look on websites
    the base clock is listed as 3.2 ghz , the unit I have is a base clock of 3.5 , I even looked at the chip again to make sure that the E was present on the processor , which it was ,cpu z reports it as 8320 E, So at stock settings it`s 3.5 and 4.0 turbo , I have a ASrock
    970 extreme 3 board so out of curiousity I set the multiplier down to 3.2 and , it didn`t want to go there, still reported 3.5,
    Guess I could force it down , so this begs the question , Is it a 8320 misbranded and 125watts or a flukey 8320e thats running 95 watts at 3.5 . I haven`t seen anything on the web from anyone else about this, Any thoughs or info?

    1. David Ramsey

      That is an excellent question. My first suggestion would be to make sure you’re running the latest BIOS for your ASRock motherboard– the 8320E came out after most 970 motherboards. So update your BIOS if needed and see if that fixes things.

    Moreover, upgrading the memory, hard drive or the most
    other components of your desktop Pc requires minimal understanding of the way in which the computer works.
    8 GB) 1600 MHz – Cost: $124. Even though the Steam sales are over,
    you can still get great games for a outrageous price.
