Speed on retina 5k iMac vs non-retina iMac?

Hi!

I'm almost ready to pull the trigger on the retina iMac. Some reviews make it seem though as if the power/speed is compromised because of the display. I have a 2012 iMac and I definitely want something faster! What do you think?

It is not. Though it may not be dramatically faster, the 4.0 version is the fastest iMac you can buy.

4.0?

It depends on the details of your 2012 iMac and what you're doing with it. Unless you are already running on an SSD, a pure SSD iMac will seem much faster on various tasks, program launching, updates, scrubbing through media files. Also the steady march of CPU improvements help on very CPU-intensive stuff like photos and video, especially batch computations like rendering.

Basically everything is faster unless it's limited by network I/O (which these days is a lot of things unfortunately...)

4.0 GHz I assume.

The only thing worth thinking about is the grfx card.

For the rest: the iMac Retina is the way to go!
