Intel’s U2500 Core Duo Yonah processor was released just a few weeks ago. The chip marked Intel’s first attempt at a dual-core ultra low-wattage CPU, and has thus far made quite a splash in the x86 world. So much so that Intel has decided to release an even lower wattage version, the U2400.

Intel’s U2500 Core Duo Yonah processor was released just a few weeks ago.  The chip marked Intel’s first attempt at a dual-core ultra low-wattage CPU, and has thus far made quite a splash in the x86 world.  So much so that Intel has decided to release an even lower wattage version, the U2400.

The dual-core 65nm Yonah-based U2400 features a 1.06GHz clock frequency, a 533MHz front-side bus and 2MB of shared L2 cache.  Intel has not released TDP specifics of the new processor, but the TDP of the 1.2GHz Core Duo U2500 was a mere 9 Watts.  During normal operation the U2500 uses less than a Watt.

Dell and Fujitsu already have ultraportable (sub-3lb) models slated for the U2500, and it would not be a large stretch to assume the U2400 will also show up in these notebooks as well.   The U2400 is expected to sell for $ 262 to distributors on September 3, 2006.
