I know everyone seems to be constantly referring to Prescott as Pentium 5, but last I checked they are planning to use the Pentium 4 name at least through the Tejas core. Things may have changed without my knowledge though. (imagine that)
Think about this, when Intel first launched the Pentium 4, they stated the architecture was designed to scale to 10 GHz. Why would they change to P5 already? P4 was launched on the Willamette core but later changed to Northwood without changing the name. As I understand it, Intel changes the name when they introduce a major microarchitectual change, not for a core change. Correct me if I am wrong.
Listen to me now and forget me tomorrow
