    AMD says it changed in WinZIP 18: http://community.amd.com/community/a...-apus-and-gpus

    I see only WinZIP 16.5 tested in reviews, though, so maybe it's wortwhile in the recent version?

    and for comparison:

    D:\Testing\!text>arc a m:\a.zip enwik9
    Compressed 1 file, 1,000,000,000 => 327,467,415 bytes. Ratio 32.7%
    Compression time: real 6.77 secs. Speed 147,702 kB/s

    D:\Testing\!text>arc a m:\a.zip enwik9 -mt1
    Compressed 1 file, 1,000,000,000 => 327,467,415 bytes. Ratio 32.7%
    Compression time: real 30.35 secs. Speed 32,954 kB/s
