We’ve been through this before. Every year we get an update to Centrino, and every year the outcome is pretty much the same: equal or better performance, coupled with longer battery life. It’s Moore’s Law in action, transistors switch faster, they get smaller and thus Intel’s engineers can do more with them to not only improve performance but reduce power as well. The end result is that each year we have to evaluate whether or not buying a new laptop makes sense.
The last Centrino update brought faster FSB speeds courtesy of the Mobile 965 Express chipset, slightly faster CPU speeds, some additional power saving technology, and Intel’s controversial Turbo Memory. Despite what was looking like a potentially major improvement in the Centrino platform (mostly because of Turbo Memory), the end result was a fairly lackluster update to Centrino. It wasn’t bad, it just wasn’t much to get excited about.
