Mobile Intel Pentium 4's revealed

AS WE'VE POINTED out in a few stories over the last few weeks, one of the more interesting family of processors Intel will launch during this year is its "Portability Processor".
These are Pentium 4s and Celerons which are based on Intel's desktop CPUs but with some differences – they're intended for so-called "transportable" notebooks.

The chips also have some interesting characteristics – at first they'll be built using the .13µ (micron) process, will have a 512K cache, and will use a 533MHz front side bus, although Intel calls this the PSB.

By the fourth quarter of this year, these processors will also support hyperthreading, and next year will start to appear as "mobile Prescotts", with 1MB of cache, hyperthreading and also at 533MHz for the bus, although produced using a 90 nanometer factory process.

It's important to note these are not Pentium 4Ms, but they do have some heat characteristics which make them suitable for notebooks, Intel will claim. As far as we can see, there won't be any Speedstep in there either.

The Celerons intended for notebooks will use the .13µ process, only have 128K of level two cache, and still support the 400MHz front side bus.

Intel wants to take advantage of the increased sales of notebooks, which is why it is introducing so many different kinds of microprocessors for the family – ranging from the very thin and light machines up to these "transportables".

No prices for these chips have been made available as yet – this will be an interesting equation when it comes. The fully-fledged Pentium 4s for desktop will all, or nearly all, use the 800MHz front side bus by the time these babies see the light of day.

Here are the projected speeds, according to recent roadmaps seen by the INQWell. All frequencies in GHz.
