The new budget Sempron chip from AMD is slower than the 32-bit Athlon XP
it replaces, according to tests from PC World. In the tests, a machine with the new chip underperformed one with a comparable Athlon XP. With the Athlon XP, the machine landed a WorldBench 5 score of 82, about 5 percent faster than the 78 score it achieved with the Sempron. AutoCAD and games tests performed also yielded similar results. However, the Sempron based system did beat a similarly configured PC with Intel's Celeron D value CPU.
