The Intel Mobile Pentium III 450 was a mobile processor with 1 core, launched in October 1999, at an MSRP of $348. It is part of the Pentium III lineup, using the Coppermine architecture with Micro-BGA2. Mobile Pentium III 450 has 256 KB of L2 cache and operates at 450 MHz. Intel is making the Mobile Pentium III 450 on a 180 nm production node using 28 million transistors. The multiplier is locked on Mobile Pentium III 450, which limits its overclocking potential.
With a TDP of 15 W, the Mobile Pentium III 450 consumes very little energy. The highest officially supported memory speed is 133 MT/s, but with overclocking (and the right memory modules) you can go even higher. Actual memory technology support depends on the chosen motherboard, because the memory controller is located on the motherboard (not in the processor). For communication with other components in the system, Mobile Pentium III 450 uses a PCI-Express N/A connection.
Many games will refuse to start on this processor due to the lack of the SSE2/SSE3/SSE4 instruction set.
