Performance in Audio Encoding Tasks (Lame)

Although a slight clock speed increase managed to make the new Pentium 4 XE 3.46GHz run faster compared with the predecessor, AMD and Intel processor retain certain parity during MP3 audio encoding.

Performance in Video Encoding Applications

Nothing outstanding happens during video encoding, too. The new CPU appeared slightly faster than the previous model, although Pentium 4 560 based on Prescott core is still faster in this type of tasks. It must be higher working frequency as well as architectural improvements and SSE3 commands support that tell here. So, if you do a lot of video encoding, then it hardly makes much sense to you to go for an expensive Pentium 4 Extreme Edition processor.
