At the International CES 2002 (Consumer Electronics Show) being held on these days Intel showcased a working notebook built by Toshiba, which used mobile Pentium 4 processor working at 1.7GHz core clock frequency. It means that the mobile Pentium 4 family is already coming.
However, as we happened to know recently, the official launching of Pentium 4-M is scheduled for March. Intel will announce four Pentium 4-M models at the same time: 1.4GHz, 1.5GHz, 1.6GHz and 1.7GHz. All mobile Pentium 4 CPUs will be built on the 0.13micron Northwood core, will feature 512KB L2 cache and will be designed in microFCPGA 478 package. The CPUs will use 400MHz Quad Pumped Bus and support Extended SpeedStep and Deeper Sleep technologies. At first, Intel will position its new Pentium 4-M CPU family as a solution for full-size and slim A4 notebooks.
As far as Intel’s ongoing plans in terms of further Pentium 4-M family development are concerned, in Q3 we expect a CPU working at 1.8GHz, and in Q4 – at 2GHz.
Together with the launching of the first Pentium 4-M processors Intel will announce two discrete chipsets supporting them: Intel 845MP and Intel 845MZ. Both sets of core logic represent mobile versions of Intel 845 supporting DDR SDRAM, however, Intel 845MP will be a more expensive solution and will cost $41, while Intel 845MZ - $36 (in the second half of the year it will sell at around $20 already). The difference between these chipsets lies with the supported memory types. Intel 845MP will support DDR266 and DDR200 modules (up to 1GB), while Intel 845MZ will support only DDR200 (up to 512MB).
As for the first integrated chipset for mobile Pentium 4-M CPUs, it will come out only in Q1 2003 and is now known as Montara-GML.
