WinZip 8.0
 






BIOS & Drivers

Test Settings Compressed Size (bytes) % Of Original Compression Time (s)
Fast WinZip 7.0 32,781,256 51.80% 23
WinZip 8.0 32,781,372 51.80% 27
Normal WinZip 7.0 32,059,666 50.66% 27
WinZip 8.0 32,059,782 50.66% 30
Max WinZip 7.0 31,888,939 50.39% 62
WinZip 8.0 31,889,055 50.39% 65

As you can see, WinZip can roughly cut the size of the average driver package by half. The compression performance of both WinZip 7.0 and 8.0 was not significantly affected by the different compression method used (Fast, Normal or Max).

But from a compression efficiency point of view, the Normal setting is the most efficient. At the Normal setting, both WinZip 7.0 and 8.0 showed only slightly poorer compression but at a significantly higher compression speed (more than twice as fast actually).

You will also notice that WinZip 7.0 consistently performed better than WinZip 8.0. The ZIP archives produced by WinZip 8.0 were always 116 bytes more than the archives produced by WinZip 7.0. That's really peanuts, compared to the total size of the files tested (63,288,349 bytes). In other words, the difference is only 0.000183%!

More important is the compression speed, which have fallen somewhat. WinZip 8.0 is now 8.2% slower than WinZip 7.0. That means the total time taken by WinZip 8.0 to complete the three tests was 10 seconds longer than the time taken by WinZip 7.0.

With highly compressible spreadsheet and word processor documents, WinZip can almost cut their sizes to a third. Using the Normal compression mode improved the compression ratio of the Fast setting by 7.2% but using the Max compression mode merely improved on that by a mere percent.

With a compression speed close to that of the Fast setting, the Normal setting is the most efficient setting. In contrast, the Max setting suffered a 62% drop in compression speed in return for an improvement in compression of only 1%.

Again, WinZip 7.0 consistently performed better than WinZip 8.0. The ZIP archives produced by WinZip 8.0 were always 106 bytes more than the archives produced by WinZip 7.0. That's really insignificant compared to the total size of the files tested (58,722,263 bytes). In other words, the difference is only 0.000181%!

More important is the compression speed, which have fallen a little. WinZip 8.0 is now 1.6% slower than WinZip 7.0. The total time taken by WinZip 8.0 to complete the three tests was about 2 seconds longer than the time taken by WinZip 7.0. Again, this is nothing great but still, for a newer version of WinZip, one would have expected some gain, not loss.
