Definitely, it's a non-cluster question, but may be<br>
I'll get an answer: is there any remarkable difference<br>

Intel CPUs, e.g. QX9650 and Q9650?<br>

of course not - the chips are the same inside, so deliver<br>
exactly the performance you expect from their operating clock.<br>
same cache, same clock, same fsb, so same performance...<br>
<br>
as far as I can seem the only difference is that the X<br>
is an older stepping, has a higher TDP and lower thermal spec.<br>
