THe Pentium M processor is the Mobile Processor you would find in a lot of laptops. The front side bus is cut down which uses a lot less power making it more ideal for a mobile set up. I think the M processors are at 400Mhz FSB, but I could be wrong. I know the cpu speed is up around 2.6 ghz, possibly more now. I am sure you can get away with doing some audio on an M processor, but you wouldn't be able to get down and dirty. I dont think there is that much of a price difference between a regular P4 and M P4, once again I could be wrong.
The above quote means that it demands less on a battery?
What is the average FSB of a P4 and what aspects of my audio production work would suffer from the M processor reduction?
What would be a recomended FSB speed for audio on a laptop in relation to price and availability?
I recently bought a Toshiba Satellite P4 laptop, which has a 533 mHz FSB - most portables are still at 400 FSB, and desktop procs are up to 800 FSB without overclocking - this determines memory transfer speeds, so is very important for any and allplug-ins etc -
However, most laptops are further choked by 4500 rpm drives, mine is no exception. This will limit track count in multitrack software. There are aftermarket drives, by Hitachi I think, that are 7200 rpm for laptops. Ive not looked into them yet, but that should speed things up some.
