Mobile Pentium III microprocessors in Ball Grid Array and micro Pin Grid Array packages included many features present on desktop Coppermine Pentium III CPUs. All mobile processors had 100 MHz Front Side Bus, 32 KB level 1 cache, 256 KB level 2 cache integrated with the core, and MMX and SSE instruction sets. The mobile microprocessors had slightly lower core voltage than desktop processors, and included additional power saving modes such as Quick Start and Deep Sleep. Majority of mobile CPUs also included SpeedStep mode. Mobile Pentium 3 processors were produced at speeds ranging from 400 MHz to 1 GHz.
