going to buy a imac but need some help, please :) (rep added for help)

Found 13th Apr 2010
one of the 27-inch macs has 3.06GHz and the other has 2.66GHz but is a quad core and more expensive, im just abit confused because i thought the more ghz is better but in this case the one with the lower ghz is the more expensive. im confused can someone please help.

The GHz is the speed of a CPU & will perform better than the quad at single task, however if you run multiple apps at the same time or use heave programs like video editing the quad core would be better.

Hope this helps

Basically, the quad core has 4 processing cores, which effectively is 4 independant processors @ 2.66ghz each.
you didnt state how many cores the other had, but im guessing less than 4, so even though each core is 3 ghz, there are less of them

lol thanks guys but im getting one mainly for graphics and video editing and i know pcs are in most aspects better then macs, but i guess they are just like a hot girl they don't need to be that intelligent when that look they good

If you are going to be video and Photo Editing and are going to be using Pro Spec applications then I would go for the quad system.

Although the Quad system is running at a base clock speed of 2.66Ghz the i5 and i7 processors have something called turbo-boost (very knight rider I know) this means the clock speed will jump to 3.33Ghz when the CPU decides it needs to do when running some more intensive tasks.

So perfect for serious editing packages.

If your doing pro work its a no brainer.

You can pick up:


Refurbished iMac 27-inch 2.66GHz Quad-Core Intel Core i5

27-inch LED-backlit glossy widescreen display
4GB memory
1TB hard drive
8x SuperDrive (DVD±R DL/DVD±RW/CD-RW)
ATI Radeon HD 4850 graphics with 512MB memory
Built-in iSight camera


From the Apple Refurb store for £1379 saving about £255 on the full price

Not really how Turbo boost works, it's based on the temperatures and how … Not really how Turbo boost works, it's based on the temperatures and how many cores are in use, 1 core used and it would go upto 3.33, using all 4 cores which any half decent video editing software will, it will stay at 2.66ghz.



Correct, sorry I wasn't as clear as I should have been.

What I was pointing at was that you get the best of both worlds.

When the 4 cores are being utilised you get the obvious added bonus there on high end pro software, when using standard single core applications you get the boost therefore getting the best of both worlds compared to a standard C2D machine.

i have the 3.06ghz model and it's lightning. I put an extra 2 x1 GB ram sticks in (which you can pick up for £15 as a set from eba.....). If you're going to be doing serious editing then I think the i7 will benefit you- just depends if you have the extra cash.
