My benchmarking marathon last week seemed to generate more questions and requests for further benchmarking. A popular request from you, Constant Reader, was to see Windows Vista 32-bit benchmarked against Windows Vista 64-bit.
You asked, I delivered. Enjoy!
The Test SystemTo carry out this run of benchmarks I chose a base system that represents the sort of system that someone might want to have 4GB or more of RAM installed and therefore want to go the 64-bit route. I'm certain that my choice of system will generate a lot of feedback relating to its suitability.
Here’s the spec of that system:
The following OS combinations were tested:
Each system was fully patched with all patches available from Windows Update.
Other noteworthy points:
This time we’re going to use a purely synthetic benchmark - PassMark PerformanceTest 6.1.
Note: With PassMark ratings, the higher the number, the better the score.
Each test was run four times and the lowest score from each run was discarded. The remaining results were then averaged to produce a final PassMark rating.
Let's look at the average PassMark rating for the four different platforms:
Taking a closer look at the PassMark PerformanceTest output shows an almost across the board improvement in performance when comparing 64-bit to 32-bit Vista (only the disk component of the test showed a decline in performance on 64-bit).
Note: If you want to take a closer look at the results, you can download them here: Vista 32-bit RTM | Vista 32-bit SP1 | Vista 64-bit RTM | Vista 64-bit SP1.
Some quick number crunching reveals some interesting data.
So far, we're seeing PassMark ratings that are in line with earlier benchmarking tests comparing Vista RTM with Vista SP1 - that is, the SP1 system returns a lower PassMark rating than RTM. OK, but this test was to compare 32-bit Vista against 64-bit Vista. Doing this gives us some very interesting results:
Advantage Vista 64-bit.
Boot Up Times
For completeness I also measured the boot up time. I took this as the time from the boot loader to a usable desktop.
Average results were as follows:
Advantage Vista 32-bit.
The results from this set of benchmark runs have turned out to be quite clear. Let me summarize the results here:
Later I hope to see which platform delivers the best frame rates in some of my favorite games.
