I desided to make a test using the latest of all programs. Latest winzip (v16), latest Winrar (v4.11) and latest 7zip (v9.20)
I compressed a full game of almost 400 MB of mixed data, video, pictures, music files. Here is the result:
7zip: 130 seconds and compressed size became 367,677 kB
WinRAR: 116 seconds and compressed size became 368,461 kB
Winzip: 79 seconds and compressed size became 365,153 kB
All programs used the best compression available.
The latest winzip beat the crap out of 7zip and winrar in terms of time and it is also smaller.
WinRar beat 7zip in terms of speed by a relatively good margin and had just a little bit extra size, nothing that will matter.
7zip had the longest compression time.
7zip compressed 2,896,160 bytes of data per second
WinRar compressed 3,252,614 bytes of data per second
Winzip compressed 4,733,117 bytes of data per second
winzip spent about 40% less time versus 7zip. If you compress 10 GB of data using 7zip and we imagine it will take an hour to do so, then winzip will spend 36 minutes to do the same, thats how serious it becomes when dealing with huge amounts of data.
