Based on the Conroe-L core. It's basically a single-core Core 2 Duo CPU with less L2-cache and a slower FSB.

As far as I know there is no production version/model of this CPU available. The fastest Celeron in this series is the Celeron 450, running at 2.2GHz.

My ASRock P45XE detects it as 'Genuine Intel(R) 2.40GHz' processor rather than model number. It also let's you configure any multiplier up to 23x despite it's only unlocked between 6x and 12x. > Read more

Intel Celeron 440 'SL9XL'

The second fastest Celeron (if you don't count engineering samples) with the Conroe-L core. It run's at 2GHz with just one core.

This CPU was sold at a low price and found it's way in low-budget systems. In practical terms it would outperform a Pentium 4 3GHz but in 2007/2008 it would've been nice to use a faster dual-core CPU.

Often these budget systems lacked a decent amount of RAM and slower smaller hard-drives. Usually not the best way to get acceptable performance from a system. > Read more
