Rendering the "Electricity" Video FX sees no benefit going from dual to quad cores, but the Mac Pro doesn't need it as the 2.0GHz configuration is already 26.5% faster than the PowerMac G5 2.5GHz.įinally we've got iDVD, an application that you can use to create DVDs that are playable on any consumer DVD player. All of the Mac Pros here are faster than the PowerMac G5s, which is what we'd expect given what we learned in the iMac Core Duo vs.
Our Macs have gotten a little too fast for the billow transition test, as the Mac Pro 2.66GHz can now complete the test in 3 seconds flat. We focused on the latter, measuring the time it takes to render the most CPU intensive transition and video effect in iMovie HD. There are two primary focuses for performance in iMovie HD, video import speed (if you are dealing with a non-DV or non-iSight video source) and effect rendering speed. The next application we looked at was iMovie HD. quad core comparison, the 2.0GHz Mac Pro is still noticeably faster than the G5. Comparing the Woodcrest based Xeons to the older G5s is no contest, at 2.0GHz the Mac Pro is already 14% faster than the 2.5GHz PowerMac G5 even if we account for the dual vs.
We included the performance of a hypothetical dual core Mac Pro in addition to the native quad offerings in order to provide a good point of comparison to the dual processor PowerMac G5s.Īlthough there's a slight performance boost when going from dual to quad core (6.9%), this test is largely dependent on clock speed within a single microprocessor architecture. After we got the time we divided it into 379 to get the number of pictures imported per second. The test is simple we timed the import of 379 photos into iPhoto which, believe it or not, is quite CPU intensive and not as I/O bound as you'd think. Even though you wouldn't expect it, iPhoto is threaded quite well and thus our import photos test gets a speedup from going to quad cores. One of the benefits of OS X and Apple's application suites is that most of the applications are already properly threaded. ILife '06 Performance with iPhoto, iMovie HD and iDVD
