Intel Pentium 4 1.9 GHz

The first Pentium 4 CPU's were based on the Willamette-core and ranged from 1.3GHz to 2.0GHz. The first series all made use of socket 423 but it didn't take long for Intel to start with socket 478. I guess most people associate 478 with the much better 130nm Northwood-core but both Willamette and the newer Prescott core found it's way on the 478 platform. So did this 1.9GHz Pentium 4, too .
