1. P4-M: The CPU For The Full-Sized Consumer Notebook

Some readers will probably be wondering why THG is benchmarking mobile Pentium 4-M processors just a few weeks prior to the launch of Intel's new Pentium M mobile processor (codenamed Banias). The explanation is simple: the Pentium 4-M, if the prophets at Intel are to be believed, will surely remain the processor of choice for a full-sized notebook in the consumer segment until the middle of the year (and probably after that, too). Even in the business segment, the Pentium 4-M will still be a force to be reckoned with.
The test results also help to answer questions asked by many people in the market for a notebook:
How fast should my notebook's processor be clocked in order to run application X, Y or Z? Can I play games on the notebook and do I need the fastest processor to do so? What effect does a higher clock speed have on battery life? What is the effect of various power schemes on performance? Why are prices for mobile and desktop processors different?Since, compared to their desktop counterparts, mobile processors are not exactly the cheapest components of a notebook, choosing the right processor when buying a notebook can save a bundle.
| Pentium-4-M/400 MHz/512 kB | |
|---|---|
| Core Frequency | Price |
| 2.2 GHz | US $348 |
| 1.8 GHz | US $171 |
| 1.7 GHz | US $171 |
| Pentium-4/400 MHz/512 kB | |
| Core Frequency | Price |
| 2.6 GHz | US $305 |
| 2.2 GHz | US $193 |
As you can see, mobile and desktop CPUs differ greatly in price for some seemingly inexplicable reason. Before we get down to the test results, let's look at the differences between a P4 desktop CPU and a P4-M processor.
