Yesterday, Apple updated its entire desktop lineup. This update had been a long time coming, especially since the Mac Pro hadn’t been updated since January 2008 and the Mac mini hadn’t been updated since August 2007!
However, a lot of people were disappointed with the updates, since it felt like an incremental update rather than a substantial upgrade. Now that Geekbench results are coming in for the new iMac and Mac mini, we can look at one aspect of the updated hardware – processor performance – and see if the upgrade is incremental or substantial.
Setup
I’ve gathered results for the latest iMacs and Mac minis and compared them against previous generations (note that results for some hardware configurations aren’t available yet; I’ll update the post when they are available). Results were collected from the Geekbench Browser for Macs with standard processors (i.e., no processor upgrades or overclocked processors). I’ve reported the average overall score for each model and processor combination.
If you’re unfamiliar with Geekbench and how it measures performance, a score of 1000 is the score a Power Mac G5 @ 1.6GHz would receive. Higher scores are better. Also, Geekbench 2 only measures processor and memory performance which is why models with the same processors but different video cards have roughly the same score.

Conclusions
Processor performance hasn’t increased substantially in the latest hardware; the performance increase seems to scale with processor speed. This isn’t surprising, since neither the iMac nor the Mac mini moved to a new processor architecture.
You might want to keep this in mind if you’re looking for a new Mac; you might be better off getting a discontinued (or refurbished) previous-generation Mac rather than one of the new Mac models.
