MPEG-4 Video Encoding: Xmpeg 4.5 and DivX 5.01 Pro
RAM performance is an important factor in MPEG-4 encoding. We used Xmpeg 4.5 encoder with the DivX 5.02 Pro Codec in order to gauge the performance of the Intel Pentium 4 2.8 against its older brothers to see how much further a 2.8GHz can take you.
The Intel Pentium 4 2.8GHz with 533FSB and 333MHz memory is able to give us a very impressive frame rate for converting movie files to DivX and MPEG-4 formats. We used a 60 minute home video transferred to the PC via Firewire for our tests. The results were very impressive indeed.
One of the most important things that is used today for any kind of file transport is archiving and compression of files. With content getting larger and larger, higher compression formats are needed in order to transmit data at an acceptable level. WinAce is one of the most powerful archivers used in business grade applications.
The 2.8GHz is able to complete its archiving tasks in just over 150 seconds. The 2.53GHz requires 186 seconds. Not a super huge gap but enough for you to start compressing another load while a similarly powered PC using a 2.53GHz is still chewing away at the frist archive file.
