Intel Core 2 Duo E4300

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 E4300 punches above its weight in our file compression and encryption tests; in particular, it punches well above its weight in the small file test, as it performs the same as the Core 2 Duo E6300.

File Decompression & Decryption:

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

File decompression and decryption performance was a similar story, with the E4300 outperforming the Athlon 64 X2 4200+ in the large file test and it even outperformed the X2 4600+ in the small file test. Meanwhile, the Core 2 Duo E6300 outperformed AMD's Athlon 64 X2 5000+ EE chip based on the 65nm Brisbane core.
