Archiving and Encryption
To test the processors performance during data archiving we resort to WinRAR archiving utility. Using maximum compression rate we archive a folder with multiple files 560 MB in total size.
There are a lot of factor affecting the WinRAR performance: clock frequency, number of cores, cache-memory size, etc. As a result, triple-core processors and Phenom II X2 - the only CPU in our session with a large L3 cache - become the leaders in this test.
The processor performance during encryption is measured with an integrated benchmark from a popular cryptographic utility called TrueCrypt. I have to say that it can not only effectively utilize any number of processor cores, but also supports special AES instructions.
Encryption is a task that can be easily paralleled, so it is absolutely logical that the triple-core processors with relatively high clock frequencies win this race. As for the results demonstrated by dual-core testing participants, Athlon II X2 and Phenom II X2 turn out a little faster than their competitors from the Celeron and Pentium series.
We measured the performance in Adobe Photoshop using our own benchmark made from Retouch Artists Photoshop Speed Test that has been creatively modified. It includes typical editing of four 10-megapixel images from a digital photo camera.
Intel processors perform faster in Adobe Photoshop. Their advantage is so significant, that a 50-dollar Celeron is even faster than AMD Phenom II X2 priced over $90.
