Integer operations are often quite cache dependent.
A leading aspect of the Pentium 4 architecture is the utilization of Intel's 400MHz NetBurst frontside system bus with dual channel Rambus memory support. Later benchmarks will demonstrate how this bandwidth advantage can be translated into increased software performance. 3DMark2000's CPU test capability proves highly useful for determining performance characteristics of different processors. Hardware transform and lighting has been disabled to ensure this test is executed without additional support from the GeForce-2 graphics chipset. To sustain the highest level of performance, 3DMark was manually configured for support of each test system's particular SIMD multimedia instructions.
