64-bit vs 32-bit tested with real-life application

@ 2004/09/04
One of the few 64-bit applications currently available is Panorama Factory, a photo stitching program to analyse and align different photographs, and generate a seamless panorama - as long as there is enough overlap between the two pictures to find the common denominators. Panoramas created by this application can use a humongous amount of memory in the process and, provided high enough magnification and resolution of the individual source images, pose a real challenge to any current processor. We have a number of benchmarks to show the performance difference between 32-bit and 64-bit ported versions of the same benchmark, moreover, we take a close look at the issues related to memory address space limitations in a 32-bit or a 64-bit environment that may be somewhat different from the current grain of wisdom and even marketing propaganda.
