BX80531NK160G - Intel Pentium 4 1.60GHz 400MHz FSB 256KB L2 Cache Socket 478 Processor

The Intel Pentium 4 Processor in the 423-pin Package socket with Intel Netburst?? micro-architecture still maintains the tradition of compatibility with IA-32 software. The Intel Netburst?? micro-architecture features include hyper pipelined technology, a rapid execution engine, a 400 MHz system bus, and an execution trace cache. The hyper pipelined technology doubles the pipeline depth in the Pentium 4 processor, allowing the processor to reach much higher core frequencies. The rapid execution engine allows the two integer ALUs in the processor to run at twice the core frequency, which allows many integer instructions to execute in 1/2 clock tick. The 400 MHz system bus is a quad-pumped bus running off a 100 MHz system clock making 3.2 GB/sec data transfer rates possible. The execution trace cache is a level 1 cache that stores approximately 12k decoded micro-operations, which removes the decoder from the main execution path, thereby increasing performance.
