The Mobile Pentium II 400 is a 32-bit x86 microprocessor, part of the Mobile Pentium II family, which operated at 400 MHz. This was the Pentium II Mobile family's highest performance processor. This processor had a TDP of 13.1 Watts. This chip was manufactured in 250 nm process and includes a smaller 256 KB of L2$ on-die. This is the only processor in the family to later be manufactured in 180 nm.
