DivX Encoding Performance
We have been using a DivX encoding test as a part of our CPU benchmarking suite for quite some time now, however the performance test has never been truly realistic as it wasn't geared towards producing a high quality DivX rip - rather it was designed to stress CPU performance.
We have since revised our benchmark and now follow the DivX 5 encoding guide published at Doom9.net . For our test title we use Chapter 9 from The Sum of All Fears DVD. We conduct a 2-pass encoding process and report the encoded FPS from both passes averaged together. The results are lower than our previous Xmpeg tests, however they are much more applicable to real-world usage.
Hyper-Threading along with other features of the NetBurst architecture give Intel the performance advantage in video encoding as you can see by our DivX results above. The Athlon 64 3400+ performs respectably but it isn't the CPU that's best for these sorts of tasks.
