Much better then celeron 900 which are locked at 2.2ghz
this old one i upgrade from ran too hot and use too much power..
this one has two mode. 1ghz and 1.5ghz max..
You can throttle it down to 1ghz so it wont use much watt
I guess the watt usage are..
15 watt and 35 watt.
it is 2 core. a nice upgrade for me.
