Core Duo T2600 (pictured right) has had its time to shine, and while it's had a good run, we're naturally looking forward to the battery savings and speed boosts promised by Intel's new "Merom" Core 2 Duo T7600 chips. Tom's Hardware has the first set of numbers for us, and things look good -- if not exactly mind-blowingly awesome. So far they've only run the more mundane office-productivity tests, but the new chip managed close to Intel's promised 20% speed boost while lasting 7% longer in the battery department. Heftier tasks will probably reveal even greater speed disparities between the T2600 and T7600, but are also likely erase most battery gains. For easy tasks the T7600 can churn through its duties and then shut of elements of the chip once they're no longer needed.
