ABSTRACT

There are many metrics when designing microprocessors. Especially, energy, power consumption and performance are the most fundamental metrics. Since these metrics are contradictory, microprocessor designers give more weight to some metrics than the other metrics. In this paper, we compare Intel Pentium 4 and Core2 Duo both qualitatively and quantitatively. Furthermore, we provide detailed comparison between Pentium 4 and Core2 Duo when running real benchmarks. Through performance counter of real processors, we calculate energy and power consumption. Performance metric is execution time. In experimental result, Core2 Duo consumes less energy and power. Moreover, performance of Core2 Duo is also better than that of Pentium 4. However, in case of bzip2 which is optimized in Pentium 4, Pentium 4 shows much better performance and lower energy and power consumption than Core2 Duo.
