Although Intel introduced a new special Pentium M processor family for the mobile market, the company isn’t going to give up the production of Pentium 4-M CPUs based on NetBurst architecture. Moreover, Pentium 4-M family will keep developing and will one by one acquire 533MHz bus, Hyper-Threading technology and 1MB L2 cache.

As we know from Intel reps, Pentium M processor family will be improving very quickly. In Q4 this year, a new Dothan core will be introduced for these particular processors. This core will feature 2MB L2 cache and a number of other enhancements. This core manufactured with 0.09micron technology is expected to push forward the performance of Pentium M processors. The working frequency of Dothan based CPUs will reach 2GHz in Q2 2004, which will allow Pentium M processors to be used in Full Size, Thin & Light, Mini and Sub notebooks little by little ousting Pentium 4-M and Mobile Pentium III from this market segment. Very soon Intel will launch the last Pentium 4-M processor with 2.6GHz core frequency. After that this processor family will stop growing.

However, Intel is not going to push Dothan into the market of Transportable notebooks, high-performance and pretty massive solutions. This is where mobile CPUs based on Pentium 4 architecture will feel at home. After a short period of calm in Q3 2003 the mobile Pentium 4 family will continue growing. Although these CPUs will no longer be called Pentium 4-M, they will become Mobile Pentium 4 processors.

If we go in a little bit more details, we can say that in Q3 2003 Intel will announce Mobile Pentium 4 3.06GHz supporting 533MHz bus. This CPU will be launched on June 8 and will cost $417. Together with this processor Intel will announce three Mobile Pentium 4 modifications working at 2.4GHz, 2.66GHz and 2.8GHz. Here I would like to point out that unlike its desktop brother, Mobile Pentium 4 will not support Hyper-Threading at first.

However, Hyper-Threading will still come to the mobile market one day. In Q4 2003 Intel will announce Mobile Pentium 4 working at 3.06GHz and 3.2GHz, which will support Hyper-Threading. These CPUs, just like their predecessors, will be based on the 0.13micron Northwood core, feature 512KB L2 cache and support 533MHz bus frequency.

In Q1 2004 Mobile Pentium 4 family will be transferred to 0.09micron Prescott core, which will provide them with 1MB L2 cache. At this time the CPU clock frequency will grow up to 3.46GHz. The bus frequency will remain unchanged: 533MHz.

The notebooks built with the Mobile Pentium 4 processors are expected to still be based on the relatively old chipsets: i852GME and i852PM.
