Intel CPU Roadmap: Less is More

Intel Mobile Processors

The mobile sector usually values battery life over top performance, so changes are less dramatic. Updates are once again in red, and you can refer to our last Intel Mobile/Server Roadmap for more information. We have split the mobile charts into two tables, one for the Banias/Dothan processors, which require less battery power and offer better performance at a given clock rate, and a second for mobile processors based off the NetBurst architecture. Intel refers to these as the "mobility" and "transportable" platforms, respectively, and we'll start with the former.

If you were unimpressed by the changes to the desktop roadmap, the mobile front has even less news. For the true mobility processors, the only new additions are the Celeron M 390 and the Pentium M 780. There are also several "greater than or equal to" entries in the latest roadmap. Whether those are uncertain due to manufacturing concerns or due to a lack of competition is up for debate. The Banias and Dothan cores were really designed with a set performance/thermal level in mind, so we do not find as much tweaking for higher performance as we see in the desktop sector. The 2.26 GHz of the Pentium M 780 is going to be very close to the maximum clock speed that the design can reach without a die shrink or a large increase in heat output.

Taking a look at the "transportable" processors, the only changes are the cancellation of the two fastest - and hottest - processors based off the NetBurst architecture. NetBurst was never really designed for the mobile sector, and most of the laptops that use these chips target the "desktop replacement" (DTR) segment rather than true mobility. The cancellations reflect Intel's acknowledgement of this fact, as well as their confidence in the Pentium M and Celeron M parts. They could have easily shipped these parts, but demand is simply not great enough to warrant it. Not only has Intel cancelled the 558 and 350 parts, but the entire NetBurst mobile line is scheduled to cease production in Q2'05. This is no real loss, as it means future laptops will simply shift to using more appropriate parts.
