vs the Mobile Intel® Pentium® 4 Processor-M
Back in the dark ages (maybe 3 years ago), desktop processors ran at 3.3Volts and were therefore hot, and if used in a laptop,
used up the battery fast. They were also very large and difficult to fit into laptop computers. In those Golden Olden days there was a
special processor made for laptops that only ran at 2.3Volts, and was somewhat smaller; about the size of a pocket calculator.
They were favored for laptops because they ran cooler and provided longer battery life. Of course they were considerably more expensive.
Over the ages, both desktop and laptop processors began to use less voltage, and they also got smaller and smaller. The MOBILE PIII Processor got down to 1.8Volts and was about the size of a large postage stamp. Then, just last fall the new Mobile Intel® Pentium® III Processor-M was introduced. It uses 1.4 to 1.1Volts, down to .095 to 1.15Volts when on battery power, and was the size of a small postage stamp using 0.13 micron technology. Then the BIG BREAKTHROUGH came. The widely anticipated and highly touted 478-Pin "Northwood" Intel® Pentium® P4 Processor, available at up to 2.4GHz w/512 L2 On-die Cache, was introduced. It uses 1.5Volts (a far cry from the older, hotter, 3.3Volts), and is the same small postage stamp size using 0.13 micron technology. WOW...what a breakthrough for laptop computers. No more reason to settle for slower speeds and pay the expensive premium for a laptop processor! Heck, these processors are faster, cooler, and smaller than the best Mobile processor available just 6 or 7 months ago. The next step was the introduction of the Mobile Intel® Pentium® 4 Processor-M. It runs at 1.3Volts, down to 1.0Volts when on battery, and it too is the same small postage stamp size using 0.13 micron technology. Now, I have to give the Mobile Intel® Pentium® Processor-M its due respect when it comes to battery life. As it requires as much as 0.55Volts less power it will give you a little better battery life. But it is a well established fact that 80% of all laptop users say they "...rarely or never..." use their batteries. They are instead after the portability of a laptop, and are almost always plugged into either AC power, or use a 12V Auto or Airplane adapter. Well, now that you know the Truth, you can decide whether you prefer the faster, less expensive 478-Pin "Northwood" Intel® Pentium® P4 Processor, or the Mobile Intel® Pentium® Processor-M.
