Corel's WinZip 17 is the product of much retooling. The company heard complaints that its engine wasn't threaded, went back, and optimized for multiple CPU cores. Moreover, it also put in the time to enable OpenCL support. At first, this only worked on AMD GPUs. But the latest version allows OpenCL support on any platform with the requisite drivers.
In our CPU-only test, we'd expect AMD's four-module design, capable of handling eight threads at a time, to turn in a lead. It doesn't, though, and Intel's Core i5 wins at stock and overclocked frequencies.
The OpenCL-based results are much closer together, though the Intel/AMD combination comes out on top again.
WinRAR shows both systems performing similarly at stock clocks, though the Intel box pulls away once it's overclocked.
7-Zip sees a benefit from the FX-8350 that must be related to its ability to operate on eight threads at a time.
