The entire Pentium D 900 series have a very unified feature and specification list that they only differ from each other in the form of clock speed and power draw. This makes the lineup ostensibly very identifiable as opposed to AMD Athlon 64 X2 processors at the moment. On the other hand, we can't say the same for their existing Pentium 4 lineup, which while being well differentiated with various model numbers, have become rather confusing due to the variety..
