All three of these archival apps are optimized for processors with multiple cores, but to different degrees.
7-Zip, for example, is known to be really well-threaded. It's certainly nice to overclock and see substantial performance gains, but the ability to schedule to eight threads concurrently via Hyper-Threading does far more for our benchmark.
WinRAR, on the other hand, cares little about the Core i7's extra features. Instead, it appears to respond to clock rate. And the fact that our two contenders run at similar frequencies means they show similarly.
Finally, WinZip's CPU and OpenCL-accelerated benchmarks get notable gains from CPU and GPU overclocking.
