AMD FX-8320E Performance On Linux

Here's a look at the AC system power consumption over a number of different tests... On average the FX-8320E had a total system power draw of 200 Watts with a peak of 347 Watts at stock speeds, or 434 Watt peak when overclocked.

The average temperature of the FX-8320E was 29C with a peak of 44C.

For those wishing to see how their own Linux system compares to the AMD and Intel CPUs benchmarked in this article under Ubuntu 14.10, you can install the Phoronix Test Suite on your own system and then run phoronix-test-suite benchmark 1501200-DE-CPUTESTSL33. This will carry out all of the same tests with the same test settings in a fully-automated manner to the ones used in this article followed by merging all of the data in a easy to analyze, side-by-side manner.

The FX-8320E could serve as a nice upgrade for those with an older AM3+ CPU currently and wishing to boost their performance without doing a full system upgrade, but when compared to the Intel Haswell CPUs, the FX Vishera CPUs have a tough time competing in most general workloads. With the many open-source Linux benchmarks shown, there's a number of specific cases where the FX-8320E was able to outperform the Core i3 4130 (~$120 USD) and in some cases even the Core i5 4670 ($210~220), but for general desktop usage a Core i3 Haswell CPU would win. If you engage in any of the (mostly scientific applications) workloads where AMD Has the upper-hand, the FX CPUs are worth considering or if you're an existing AM3+ owner wishing to upgrade but otherwise devout AMD Linux users would be better off waiting for AMD's future products.
