Intel Core 2 Extreme QX6700

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.

We saw some nice performance improvements in our large file compression test, such that it was the fastest time we’ve seen in that particular test. However, these performance advances were mooted when compressing a large selection of smaller files and the Core 2 Extreme X6800 was the faster chip at churning through large batches of small files.

File Decompression & Decryption:

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

You can expect the same performance as a Core 2 Duo E6700 from the Core 2 Extreme QX6700 in large file compression, but performance decreases on the quad-core chip when you start decompressing a smaller batch of files from an archive.
