An interesting suspicion:

One other way to possibly bypass Intel "protection" :

Since Windows XP is using a CPU driver located into
c:\windows\system32\drivers\amdk7.sys or amdk6.sys, I think that we
could be able to modify the AMD CPU's ids by changing the "line" that
specify the id. Thus, people running Athlon could see their
performances increase. So it would be rather simple... in theory.
Or why an AMD user couldn't use a P4 driver ? That way people might
get benefits onto their AMDs.
We could also create a program that emulate a P4 id. I don't think
that so complicated...

In fact, the "compiler trick" would be the reason why Intel gets
better performance on 3DSMax, Media Encoding, several games,
...However, I mustn't misapprehend : it's only a supposition.
