Intel Corporation introduced the Pentium 4 in 2000 as its premier family of processors for personal computers. However, when the company faced the problem of fitting the chips into laptop PCs, Intel designed a new line of processors for such an application in 2002. It was dubbed the Mobile Intel Pentium, or Intel Pentium M. One of its entries was the 1.8-gigahertz (GHz) Pentium 4 M.
Manufacture
The Intel 1.8 GHz Pentium 4 M is a single-core processor, meaning it has one processing unit. The single core is placed on a 131 square-millimeter die that contains 55 million processing transistors. Intel used a 130-nanometer (nm) lithographic node to manufacture the chip.
Speeds
The 1.8 GHz Pentium M is named after its clock speed. Thus, it performs its fundamental tasks at 1.8 gigahertz. The clock speed range of the Mobile Intel Pentium 4 is between 1 GHz and 3.46 GHz, thus placing the 1.8 GHz processor at the lower end in terms of processing performance.
The processor also has a front-side bus (FSB) speed. This is the rate at which the processor transfers data with the computer's motherboard using the system's front-side bus. The 1.8 GHz chip has a FSB speed of 400 megahertz (MHz). The other available speeds for the Mobile Intel Pentium 4 are 533, 666 and 800 MHz, therefore placing the 1.8 GHz at the bottom of this category.
Cache
Each processor has a cache, or memory bank, which is used to store the laptop's most frequently used data. This feature makes it quicker for the processor to access information; it does not need to go to the random-access memory (RAM) to do so. For the Intel 1.8 GHz Pentium 4 M processor, the cache has 512 kilobytes (KB).
Power and Voltage
Each Mobile Intel 1.8 GHz Pentium 4 chip uses up to 30 watts of power. With a Pentium 4 M power range of 5 to 88 W, the 1.8 GHz is one of the best power-conserving chips in this particular family of processors. Additionally, it uses 1.3 volts for its operation.
