laptop processor
Today a went to purchase a laptop, when I got to the shops I noticed the processors were 1.40/1.60/1.80 MHZ Intel Celeron M 380 this to me appeared to be half the speed of my daughters P4 2.8 I purchased for her two years ago. I asked the seller how come these chips have halved their speed. He reckons with the M 380 chip it’s actually twice the speed that is advertised so 1.40 is actually 2.8MHZ he said Intel have advised them of this. Any thoughts here?

The architectures of the P4 and the Pentium/Celeron M line are different. Even though the M line of chips are clocked at a lower frequency, they perform on par with and at times better than faster clocked P4's. HTH

Laptop processors scale more in line with the new Core 2 Duo desktop chips. So a 2 GHz one should give performance roughly in line with your P4 2.8, maybe even better.
Interesting article comparing the Dothan Pentium-M with many desktop CPUs including P4s: http://www.tomshardware.com/2005/05/...over_netburst/
