7-Zip is a file archiver with a high compression ratio.
The built in 7-Zip benchmark shows us a few different things here. The Intel Core i3 2100 is again behind all other CPUs, mostly due to its relatively low clock speed and only having two physical cores. AMD CPUs do relatively well in this benchmark suite. The Intel Core i7 2600K is once again on top thanks to its high clock speed and Hyperthreading.
