To isolate the impact of scaling core counts, we picked the Gigabyte board for its ability to enable anywhere from one to six active cores in the BIOS. We chose to examine results using two, four, and six cores. For each of these, we tested both with and without Hyper-Threading enabled, giving us essentially six different (logical) thread count scenarios. This would also hopefully help us see how much, if any, benefit there is to having Hyper-Threading in play with CS5. 

Figuring that most people running Creative Suite would be unlikely to purchase a Core i3, we left Turbo Boost enabled across all tests. Note that when we measured CPU ranges, it was done by waiting ten seconds after launching the test and observing utilization for at least two minutes total across multiple areas within the test run. The lowest and highest observed utilization values were discarded unless seen to repeat at least twice.

Having 12 GB was important for us, because in upgrading from CS4 (or earlier) to CS5, we’re assuming that one of the main draws is to also make that leap from 32-bit to 64-bit and leverage the increased memory addressing that comes with it. When testing CS4, we still have 12 GB of system memory in the configuration, but the applications only access the first 4 GB of it. In one sense, this muddies the waters a bit since we’re effectively changing the hardware resources utilized along with the applications, but ultimately we decided this best reflected a real life decision process. If you’re going to pay for a CS5 upgrade, odds are high that you’re going to increase your memory along with it, and 12 GB is a sweet spot for triple-channel memory kits in today’s high-end systems.

We also debated for a while over the storage devices to use here. Ultimately, we decided to use Intel’s widely respected G2 SSD to house our OS and applications, while all data and scratch disk targets were placed on the OCZ RevoDrive.
