Intel Corporation introduced Tuesday a number of powerful Mobile Pentium 4 microprocessors designed for notebook computers that are used primarily as desktops. The announcement reflects Intel’s intention to transit all NetBurst-based chips to the 90nm fabrication process.

The Mobile Intel Pentium 4 Processors are designed for larger-sized notebook PCs, also known as “desktop replacements”, typically featuring large screens, full-size keyboards and multiple drives. Mobile Intel Pentium 4 processors 538, 532, and 518 are based on the Prescott architecture and feature 1MB L2 cache, SSE3 technology and the HyperThreading. The chips bring no clock-speed increases over predecessors, even though they are made using thinner 90nm process technology compared to predecessors, and are available in 3.20GHz (538), 3.06GHz (532) and 2.80GHz (518) speed-bins.

The new Mobile Pentium 4 processors feature power management Enhanced Intel SpeedStep technology that enables lower thermals than its desktop counterpart providing more reliable system performance in a notebook. Thermal design power (TDP) of the new “Prescott” Mobile Pentium 4 processors at the speeds of 2.80GHz, 3.06GHz and 3.20GHz is 88W. Intel also tells notebook makers that future direction of TDP is 94W, seriously more compared to 76W thermal design power of previous generation Mobile Pentium 4 chips produced using 130nm process technology.

The revamped Mobile Intel Pentium 4 processors made using 90nm fabrication process utilize 533MHz Quad Pumped Bus and are compatible with Intel 852GME and Intel 852PM chipsets.

Separately Intel unveiled Celeron M 340 (1.50GHz) processor with 512KB of L2 cache and 400MHz processor system bus for value mobile computers.

In 1000 unit quantities, the Mobile Intel Pentium 4 Processor 538, 532 and 518 are priced at $294, $234 and $202, respectively; the Intel Celeron M Processor 340 is priced at $134.
