Macworld | Review: 20- and 24-Inch Aluminum iMacs (2008 Edition)
May 8th, 2008 | by Tony Steidler-Dennison |(Via Macworld.)
Macworld Lab ran the three new standard iMacs through our customary suite of tests to gauge performance improvements on the previous generation. The new 2.8GHz 24-inch iMac showed a 30-point (13 percent) Speedmark improvement on the previous high-end model, a 24-inch 2.4GHz iMac. However, this new high-end iMac posted the same Speedmark score as the previous build-to-order model, a 2.8GHz 24-inch model. The new low-end iMac, a 2.4GHz 20-inch model, had a Speedmark score that was 26 points higher (13 percent faster) than the previous low-end model, a 2GHz 20-inch iMac. Also, the new 2.4GHz 20-inch iMac scored 9 points lower than the older midrange iMac, a 2.4GHz 20-inch model. But as we pointed out in our earlier Macworld Lab benchmark report of the new iMacs, the older 2.4GHz 20-inch iMac that we tested had a larger hard drive and a better graphics card than the new entry-level model, which explains the speed difference.
