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 1.4 GB in total size.
Archiving algorithms work with data aggressively that is why A8-3800 is naturally ahead of the Athlon II X4 630, because Llano has larger L2 cache. However, it doesn’t save the newcomer from being defeated by inexpensive LGA1155 processors with almost 30% better results in WinRAR.
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.
Dual-core Sandy Bridge processors are not always ahead of the quad-core AMD APUs. The diagram shows just the opposite situation this time. A8-3800 encrypts data way faster than Core i3-2100, which Intel deprived of encryption instructions support. However, Athlon II X4 630 still remains unreachable, because of Llano’s low clock frequency.
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.
Adobe Photoshop has never favored AMD CPUs. Now things have become absurdly bad. Core i3-2100, which costs about the same as AMD A8-3800 is almost 70% faster than the new AMD processor. AMD is long due for a dramatic microarchitecture upgrade and hopefully when Bulldozer comes out we won’t see poor results like this any more.
We have also performed some tests in Adobe Photoshop Lightroom 3 program. The test scenario includes post-processing and export into JPEG format of a hundred 12-megapixel images in RAW format.
Batch image processing in Adobe Photoshop Lightroom is well optimized for multi-core architectures. Therefore, unlike Photoshop, A8-3800 does pretty well here. It is especially pleasing to see that Llano outperforms Athlon II X4 630, which means that in a number of cases new Husky cores do deliver a performance boost compared with the previous-generation processors.
