7-Zip
Website: 7-Zip
Our community requested the inclusion of 7-Zip, a free compression tool that is an alternative to WinRAR and we've obliged accordingly. Using the internal benchmark this measures compression and decompression performance in MIPS and provides an average result. It is multi-threaded so takes advantage of the latest multi-core and SMT enabled CPUs.
We left the benchmark to accumulate 10 runs using a 32MB Dictionary size in order to get a solid, average result.

With the biggest positive margin yet, the overclocked Core i7 920 stretches out a ma-hoo-sive lead of 230-240 percent over baseline, and it's over 100 percent better value than #2 in the table - the Core i7 965. Again all the Core i7's provide good value for 7-zip compression performance here, despite the increased cost of CPUs and platforms it's clearly worth the investment in this test.
The overclocked Q6600 also performs exceptionally well, with naturally the DDR2 platform edging a positive lead in the total platform cost. The AMD's are also again great value on both counts offering nearly 50 percent upwards in all cases.
