The slowest official Pentium 4 for S478 socket. It was launched together with the faster models up to 2GHz.

In the wild these 1400MHz is an uncommon CPU. Usually the 1400MHz parts are made to fit the older S423 and it seems that faster models (1,5 to 2,0GHz) were sold more. Especially 1.6, 1.7 and 1.8GHz models.
