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.

System performance in WinRAR may be affected by many things: clock frequency, number of cores, cache-memory size… However, it is very likely that it is the cache-memory that plays the ultimate role in this case. For example, Core i5-750 with an 8 MB L3 cache retains the leadership and is closely followed by quad- and six-core AMD processors featuring 6 MB L3 cache.

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 process that can be well paralleled, so no wonder that the six-core Phenom II X6 1055T is the winner here. Also, quad-core AMD processors performed very well here: they left behind all of Intel competitors including Core i5-600 CPUs supporting special AES instructions.

Image Editing

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 work faster in Adobe Photoshop. And their advantage is so dramatic that the best competitor CPU, Phenom II X4 970, loses to all Core 2 Quad and Core i5 products.
