Being pedantic, but it's important: the Pentium doesn't "have" anything. Some architectures are better suited to some tasks, though. http://www.hardocp.com/article.html?art=NTI0LDM= http://www.anandtech.com/showdoc.aspx?i=2275&p=13 http://www.anandtech.com/showdoc.aspx?i=1783&p=18 http://www.anandtech.com/showdoc.aspx?i=1783&p=19 If there were such a thing as lame or a video {en|de}coder for MS-DOS (or any single-tasking OS, for that matter), the P4's super- deep pipeline would just eat thru the data. > it will work better than the AMD, regardless of the > frequency the chip runs at.
