All Pentium 4 Models | Hardware Secrets

The first Pentium 4 models were based on Willamette core, which had 256 KB L2 cache, worked externally at 400 MHz (100 MHz transferring four data per clock cycle), SSE2 instructions support, 0.18 �m manufacturing process and 42 million transistors, using an area of 217 mm2. The metal alloy used on the transistor interconnections was aluminum.
