Special thanks goes out to the folks at Macminicolo, for posting these benchmarks of the new 2011 Mac mini. This graph here shows how the Mac mini has shaped up to perform since its first release. This includes both the Mac mini and Mac mini Server processors.
Looking at the 2.66ghz Mac mini (Mid 2010) model with a score of 4040, even though the base model 2.3ghz Intel Core i5 sports a dual core processor it still manages to post a very impressive score of 6396. Which is more than 2000 over the last generation Core 2 Duos. Then when we take a look at the 2.0ghz Quad Core i7 on the Mac mini Server (Mid 2011). Even though it has a low clock speed of 2.0ghz, the four cores manage to out perform all the dual core processors by a long shot. With a score of 9573, it is more than 3000 up from the baseline 2011 Mac mini and more than 5000 by the top end Mac mini (Mid 2010) model.
So no matter which Mac mini you decide to pick up this time around, they will all perform impressively compared to that of older models.
