The Athlon XP 1800+ comes out ahead, as expected, in every SPECviewperf test here. Its largest margin comes in the form of the MedMCAD test by about 12%. That test is by far the most general and complete when comparing the system speed in terms of professional 3D applications like Povray and 3D Studio Max. The Athlon XP processor has less success in the Awadvs-04 test, which uses only the pure processor speed and doesn’t take a lot of advantage of the Palomino core enhancements.
The score of the Athlon XP here is simply outstanding! Coming in over 13% faster than the 1.4 GHz Athlon and 47% faster than the Duron 1.1 GHz this is by far the fastest I have seen the ScienceMark test go on a system. A simulation program like this takes advantage of the data prefetch and look-aside buffer enhancements of the XP processor.
The memory scores from Cachemem are now obviously 100% dependent on the motherboard and the processor has little to do with it. While the Duron is far behind, that is because the system bus on the board is running at only 100 MHz. The difference between the Athlon XP and Athlon Thunderbird is too close to call or even really give any percentages on.
