Multi-threaded applications will definitely allow the new
Pentium 4's Hyperthreading technology to shine.
Applications such as Adobe Photoshop 7, Newtek Lightwave and
XMPEG have been coded to take advantage of multiprocessor
systems and as a result, will directly benefit from
Hyperthreading as well.

Where multithreading and
Hyperthreading take flight |

We took a standard MPEG 2 format
video clip and converted it to DIVX with the most recent
5.02 CODEC installed. Here are the results.
Higher Scores, In Frames
Per Second , Mean Better Performance
As you can see,
not only does the Pentium 4 dominate this test but the
Hyperthreading enabled P4 pulls ahead of the non-HT CPU by a
commanding 16% margin. The standard 3.06GHz scores
scale accordingly versus lower clock speed processors.
The 3.06GHz P4 is roughly 10% faster than a 2.8GHz chip.
In case you
haven't heard of Main Concept's video conversion utility,
here's a link to their site. We used their AVI to
MPEG converter that you can also download and test for
yourself. We took a relatively small 5MB AVI file and
converted it to MPEG format and used the "DVD" type option
for conversion. The results here fall pretty much in
line with expectations. However, once again we see the
benefits of Hyperthreading, with the HT enabled system
coming in some 11% faster than the standard P4 at 3.06GHz.
