Intel Mobile Pentium 4

Logo of the Intel Mobile Pentium 4

The Mobile Pentium 4 (previously marketed under the name Pentium 4 M and Pentium 4 Mobile ) is a notebook processor based on the NetBurst architecture of the Pentium 4. Similar processor cores are used here.

history

Because of the relatively high power dissipation of the Mobile Pentium 4-series Intel began developing a special notebook processor , the Pentium M .

description

The first Pentium 4 M models are operated with a core voltage of 1.3 V instead of 1.5 V (for the desktop counterpart) and do not support Hyper-Threading . The core voltage is reduced by a further 0.1 V when the load is low. The system clock is 400 MHz, and some power-saving technologies such as Enhanced SpeedStep and Deeper Sleep are built in. The Pentium 4 M models were available with clock rates from 1.2 GHz to 2.6 GHz. The Pentium 4 M consumes significantly less energy and thus generates less heat than the Pentium 4. For models introduced later, different values ​​for voltages and clock rates apply (see model data).
