What is the Celeron M?
The Celeron M is not your everyday Celeron processor, given that it derives from the great Pentium M. The 65nm Celeron M is based on the Core Duo. The datasheets provided by Intel indicate that the Celeron M silicon has exactly the same dimensions as the Pentium M/Core Duo. The distinction between the Celeron M vs Pentium M/Core Duo is that the cache and core is reduced by one-half. But users shouldn’t worry too much about the smaller cache. This is due to Pentium M architecture has between 10-12 stages (unconfirmed), making it less dependent on the large cache size (as did the earlier P2 and P3, Celeron kicked ass.) Now, there are 3 types of Celeron M: Banias 130nm Core (900 MHz – 1.5 GHz with 512 KB L2 Cache) Dothan 90nm Core (900 MHz – 1.7 GHz with 1 MB L2 Cache) Yonah 65nm Core (1.06 GHz – 2.0 GHz with 1 MB L2 Cache, SSE3) About performance, the Celeron M will outperform the P4-M brother by a good 35-40%. So the fastest 1.5 GHz equates to P4-M 2 GHz. The Banias core is about 5% slo
