Panorama Factory and the $64-bit Question What's in a Benchmark...?
(Review by MS, September 2, 2004)

Test Configuration

We benchmarked the different scripts of Panorama Factory in the following hardware configuration:

*we already mentioned that at the time of the review there were no compatible ATI 64 -bit drivers publicly available, also, the VIA chipset drivers supplied with the 64-bit edition of Windows XP appear to work just fine and the Hyperion drivers only add support for RAID etc.

One thing that almost goes without saying is the fact that the amount of system memory will play a critical role, especially in applications commanding several GBytes of memory. In general, the same principle applies to greater amounts of system memory as does to 64-bit computing vs. 32-bit computing, the access of the data is much faster and that will reflect in better system performance. On the other hand, with wider and deeper registers on the CPU, changes in the amount of system memory may cause different effects on the 32-bit application than on the 64-bit application.

Performance Variability

For starters, let's take a look at the difference in performance in consecutive runs without rebooting when only one GB of memory was used.

     

Left: 32-bit version of Panorama Factory, right: 64-bit version of Panorama Factory, in both cases, system memory was 2 x 512 MB DDR in Dual Channel mode. Green: 1st Run, Red: 2nd run, shorter is better
