Adobe Photoshop Elements 4.0

For our Photoshop Elements test, we used a selection of 400 three megapixel photographs taken in a variety of surroundings using the batch file processing function in the Elements Editor. We performed all of the auto fixes, including Auto Levels, Auto Contrast, Auto Colour and Sharpen before resizing the image to 640x480 and saving as a high quality JPEG.

At low latencies, the OCZ is faster than Kingston's modules, but at stock speeds the Kingston nudges ahead of OCZ's memory. With both modules running at their highest overclock with 7-7-7 timings, performance is very similar with the OCZ just two seconds faster. That can be attributed to the fact that the CPU front side bus is running 8MHz faster.

File Compression & Encryption:

Our file compression and decompression tests were split into two halves to cover a broad spectrum of performance. The first test we ran was to compress and encrypt the MPEG-2 source file from our video encoding test with the highest quality compression ratio. Secondly, we compressed and encrypted the folder of 400 photographs used in our Photoshop Elements test with the same compression settings.

The OCZ is again faster at lower latencies, but the Kingston is better at stock speeds.

File Decompression & Decryption:

The two RAR archives created during the compression and encryption tests were then decompressed and decrypted.

In our decompression test scenarios, the Kingston outperforms the OCZ on nearly all accounts, with the Kingston several seconds ahead in some cases in this short test.
