Both
Intel, and
AMD's marketing departments don't see the point in changing a product name at every step in the development process, these core names surface only when you are looking very closely at the differences between the performances of two chips; for instance a
Celeron 300A, was a much coveted chip during its' time, because it had half the
L2 cache of a
Pentium 3 which went twice the
speed of the 512k of a
Pentium 2 300 and as such, did better doing specific tasks while being easily overclockable, and available cheaply.

CPUs that are both Pentium X, and Celeron have their L2 cache, either reduced or removed to cut costs and to change its' designation to Celeron
