Mobile Pentium III microprocessor family is based on Pentium III Coppermine core and includes many features present in desktop Coppermine Pentium III CPUs. All mobile processors have 32 KB level 1 cache and 256 KB Advanced Transfer Cache integrated on the die. All mobile microprocessors operate at 100 MHz Front Side Bus and include support for SSE instructions, that were introduced in Pentium III Katmai core. The mobile microprocessors have slightly lower core voltage than desktop Coppermine processors. In addition to lower core voltage the mobile processors include new power-saving modes that save battery power by temporary suspending the CPU:
  • Quick start mode - this mode offers better power savings than standard Auto Halt or Stop Grant modes. CPU exit time from this mode is shorter than exit time from the AutoHalt/Stop Grant modes.
  • Deep Sleep mode - this mode offers the best power savings, but CPU exit time from this mode is the slowest.

Majority of mobile Pentium III microprocessors also include SpeedStep technology. This technology allows the CPU to switch to battery optimized mode. In this mode the processor has lower frequency and lower core voltage, which greatly reduces processor's power consumption. Typically, switching to battery optimized mode can cut CPU's power power consumption in half.

I graduated to the Dell C series Latitude laptops, each of which use mobile Pentiums upto the Tualatin ranged 1200. Depending on the serial under the Dimm2 slot, it can be determined which will work with higher CPUs. I cannot determine from this, however, why one with a 900Mhz chip won't work but put in the one lower at 850 (speedsteps slower) and it will. I will be trying the 900 CPU in a Compaq Evo n600C soon. Someone said the C640 Dell's Pentium4 at 1800 was somehow sluggish compared to the spritely P3 mobiles. These also have fans over their desktop brethren from my findings
