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.These are made on the 90nm process, using a 533MHz FSB. They are compatible with the Intel 852GME and 852PM chipsets. Also unveiled was the 1.50GHz Intel Celeron M 340 with a 512KB L2 cache and a 400MHz FSB.
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.
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.
