Hands-On Report: Mac OS X 10.4.5--How Fast Is It?

Last Wednesday (2/15), Apple released Mac OS X 10.4.5 Update to Tiger for the Power PC CPU, Intel CPU and server editions. As frequent readers know, we have benchmarked virtually every release of Mac OS X from the original 10.0 release through 10.4.4 to keep track of the improvements in its speed, a major complaint initially about Mac OS X. Mac OS X runs very well these days and its recent speed enhancements have largely focussed on graphics.

So how fast is it? Did 10.4.5 speed anything up or slow anything down? To determine this we ran our usual suite of speed tests on our three test-bed Macs. The speed tests are composed of a series of "canned" benchmark applications and several so-called "real world" tests that anyone can repeat on their own Mac for comparison by following the steps that we perform.

Our long-term test Mac (since Mac OS X 10.0) has been a mostly-stock, year-2000 vintage 450 MHz Power Mac G4 Cube with 704MB RAM. We also used Apple's top-of-the-line Power Mac G5 Quad that is stock except for an additional of 2GB RAM to 2.5GB. Our third test Mac is a 20" 2 GHz iMac G5 (Rev. B), stock in every way, to represent a recent mid-range Mac.

Here are the results for the G4 Cube using Mac OS X 10.4.4 and Mac OS X 10.4.3, 10.4.2, 10.4 (Tiger) plus the last update of 10.3.9 (Panther). Other versions back to 10.0 can be found in our previous articles:

*Average of three runs. Red is much faster. Blue is much slower.

For this now low-end Mac, there are no real improvements in 10.4.5. The QuickTime Export is back down to an ambient level and file duplication is faster but not by over 10%. There is, however, a significant increase in time to shut down. This did not happen with the other test Macs so it is a mystery to us like the shut down time increase for the Power Mac G5 Quad with 10.4.4.

The results for the 20" 2 GHz iMac G5 show no real differences between 10.4.5 and 10.4.4. The Xbench Quartz Graphics score is lower but not by over 10%.

Here are the Power Mac G5 Quad's results comparing 10.4.5 with 10.4.4 and 10.4.3:

For the current top-end Power Mac G5, the Quad 2.5 GHz, there are two differences of note between Mac OS X 10.4.5 and 10.4.4. First, the Quad's time to shut down under 10.4.5 decreased back to the 10.4.3 level. We could not isolate a reason for the previous increase nor the current decrease. Second, the one application that really decreased in performance is iMovie HD 6.0.1. It took over twice as long for the new iLife '06 application to export a full quality DV movie from the test clips. We believe this is due to the iMovie HD 6.0.1 application and not 10.4.5 since the time did not increase for v 5.0.2 used on the iMac G5 or v3.0.3 used on the G4 Cube.

Mac OS X 10.4.5, like the other 10.4.x updates, has mainly security, compatibility and stability improvements and no real speed improvements. We have used Mac OS X 10.4.5 for nearly a week on a number of Macs and PowerBooks without running into any new or significant problems. [Bill Fox]
