Benchmark Results: Applications
Creation of a PDF document from a 100+ page PowerPoint file takes quite some time, and it's quickest on the Intel dual-cores, since the app isn't very well threaded.
Photoshop is well-optimized for multiple threads, allowing AMD’s Phenom II X4 905e to compete with the Intel dual-core CPUs.
WinRAR is thread-optimized, but it doesn’t run as well on AMD's quad-core model as it does on Intel's dual-core chips.
WinZip is single-threaded. Since Intel pairs high clock speeds with more performance per clock, it dominates here.
