"Intel says Socket 478's extra pins for power and ground connections improve stability for higher clock speeds. The older, larger Socket 423 will be phased out over time, and Socket 478 will supplant it. For the time being, the Pentium 4 will be available in both packages at speeds up to 2GHz"
I know...well, nothing about intel CPUs, but from what I can see the s478 is the newer model, apparently smaller adn more stable..the s423 seems to have a lot of visable green PCB bordering the core, see image at:
