Powerpage has published a XBench test from the MacBook Pro 2GHz and compared it to a PowerBook G4 1.5GHz.
On average, the MacBook is 77% faster than the previous model.
Please note that XBench is far from being a realistic test for everyday usage of the computer.

Our friends at
Mac4ever told us that a
Macrumors forum member has tested the battery life of his laptop. It lasts three and a half hours in normal usage. This corresponds with the preliminary information that we provided you.
Matbe has some information on Intel's next processors, Merom (portables) and Conroe (desktops).
These processors are Intel's answer to the speed race with AMD, as they should be 20% faster at the same frequency than the Athlon 64 X2.
This gain will be in large part because of the reduction of the pipeline to 14 stages (which is much shorter than the P4), while also benefiting from a prediction algorithm which was planned for the longer pipelines. The 4 MB of cache will also add to the performance gain.
The site also provides the mobile processor roadmap from Intel:
