DFI Infinity 975X/G

Adobe Photoshop Elements 4.0

For our Photoshop Elements test, we used a selection of 400 3MP 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.


The DFI Infinity 975X/G is a fraction slower than the Intel D975XBX mobo, but it is as fast as the other fastest boards we've tested. The CrossFire overhead is a couple of seconds at most.

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.

Again, in compres-encryption the DFI 975X/G as fast or faster than the other boards and some more expensive boards we're comparing to. The multi-GPU overhead overall is negligable. We found that memory performance has quite a large effect in our compression tests here.

File Decompression & Decryption:

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

The Infinity loses out to the D975XBX by a few seconds in the small file decompression test, but large file decompression is virtually the same. This test is somewhat dependent on hard disk write speeds, on top of CPU/memory performance and the DFI 975X/G delivers similar performance to the other boards on test.
