Hexus reviewed Intels Celeron 2GHz and pushed it to a humble 3.15GHz :
At least Intel have modernised the Celeron processor to some degree. The fact that it overclocks so easily bodes well for increasing the basic clock speeds to the 3GHz level, should they need to. I just feel that the debilitating effects of only specifying 128kb of L2 cache really do impact heavily upon performance if your inclination is towards gaming or SETI. Intel have made sure that the Celeron cannot pose a realistic threat to their P4 processor when evaluated through a number of benchmarks.
