Refreshed Apple iMac 2011 Speed Tests: Faster By Far

As most of you may already know, Apple has released its 2011 iMac range, consisting of four new models for us to salivate over. Being an iMac user I was as keen as any to see just what Apple had done to improve the family.

Before we get into the whole “My Mac’s faster than yours” scenario, lets just refresh our memories as to what we have available from our local Apple Store.

First on the list is the base level 21.5-inch iMac, which at $1199 offers 2.5GHz Core i5 quad core processing and a 500GB hard drive. Complementing this is AMD Radeon HD 6750M graphics and 512MB video memory. Staying with the same size screen the next offering has the addition of 2.7GHz Core i5 quad core processor. Whilst packing the same video memory, for the extra $300 you get 1TB hard drive along with Radeon HD 6770M graphics.

Moving up screen size to 27-inches, third in the range secures the same spec as the $1499 21-inch model but obviously on a larger scale with a price tag of $1699. Rounding up the quadruplets comes the $1999, 27-inch iMac, furnished with the larger display along with a 3.1GHz Core i5 quad core processor and 1TB hard drive. The top of the range model also sees AMD Radeon HD6970M graphics and 1GB video memory.

While Computer World notes, all four run on Intel Sandy Bridge processors, we wanted to know just how much faster the 2011 models were compared to the outgoing versions. Bench tests showed that although when each unit was tested against its 2011 brothers, speeds didn’t change dramatically. However when compared to the previous models, bigger changes were afoot.

As Apple’s own advertisement states, it’s new iMac range features nearly twice the processing speed with advanced graphics and ultrafast Thunderbolt I/O.

Starting with the entry level iMac, an overall speed increase hit the tables at almost 24 percent faster than its year old sibling, it also managed to be 10 percent faster than last years top end unit. Moving up in the price bracket, saw a 25 percent increase over previous models. When you compare the four young guns, the percentage scoring saw nearly identical increases to the models that they replace.

Our very own CEO has just taken delivery of the 27-inch iMac with the 3.1GHz option, and is more than impressed with the upgrade in performance. Let us know if you have recently upgraded your iMac, have you noticed an improvement?
