Thanks to PAQer who pointed me to these news.
I got a quite bad exprerience with WinZIP I must say. First of all I cannot reach official page in normal way. If I try to access the winzip.com then I always redirected to allsoft.winzip.ru partner site, where they try to sell the obsolete 16 version, not the 16.5 I suppose. Only if I write winzip.com/en then I access the original page.
If you'll decide to install it then I must warn you. Prepare for one of the worst install procedures ever
At almost every step it tries to offer you something that you probably don't want to have. Forget about console. The one which is available for download is obsolete and doesn't support the OpenCL, so the only way to measure the perfomance is the stopwatch.
Testbed: 571 JPG files with total size of 1 434 144 063
OS: WinXP x64 SP2
CPU: i5-2500K @ 3700 MHz
Software: WinZIP v16.5 #10095 (x64 version), PackJPG v2.5
And now the funny thing. I have ATI HD 4770 and it doesn't support the OpenCL. At least according to Wiki page and GPU-Z software, which claims that there is no OpenCL supported by my card. So the question is: where such performance comes from? I monitored CPU usage with Proccess Explorer and found that with OpenCL option turned on, WinZIP utilizes all 4 cores at maximum, giving overall CPU load of 99%, while without OpenCL option it reaches maximum 35-40% of CPU load.
WinZIP default 1 138 657 863 283 sec.
WinZIP OpenCL 1 138 657 863 105 sec.
PackJPG 2.5 1 118 417 119 821 sec.
I wonder if there is a real support for OpenCL or its just a fake?
Also I noticed that multi-core support is available for compression only. Decompression of zipx archive took 409 sec, which is 4 times slower than compression speed.
