Does Celeron Centrino Exist?

If you pay close attention, you will find some stores selling “Celeron Centrino” notebooks. There is just one detail: Celeron Centrino does not exist.

In order to be called Centrino, a notebook must have three components: Pentium M processor, Intel 915 or 855 chipset and Intel/PRO wireless LAN. You can see this at So, notebooks based on Celeron M cannot be called Centrino because they are not based on the Pentium M CPU. Even notebooks based on Pentium M that don’t have Intel/PRO wireless LAN or Intel 915 or 855 chipset cannot be called Centrino.

The differences between Pentium M and Celeron M are basically the external clock rate and the amount of memory cache:

At first calling Celeron M as Centrino wouldn’t be a problem. However, this causes certain confusion on the market. A “1.6 GHz Centrino” is faster than a 1.6 GHz Celeron M, since a Pentium M is faster than a Celeron M running at the same clock rate. The problem is the user buying a 1.6 GHz “Celeron M Centrino” thinking that it will achieve the same performance of a “real” 1.6 GHz Centrino, which won’t happen.
