Firstly, this thread assumes there will be a 2013 iMac released this fall. Naysayers can dispute this in the appropriate thread HERE.
At the high end, here's what I think we'll see for Haswell CPU options:
Model Cores Threads Frequency Turbo Frequency L3 cache Max GPU Frequency TDP
Core i5-4670S 4 4 3.1 GHz 3.8 GHz 6 MB 1200 MHz 65 Watt
Core i7-4770S 4 8 3.1 GHz 3.9 GHz 8 MB 1200 MHz 65 Watt
As far as the GPU goes, I sure hope Apple offers an upgrade option to the 780M which is the mobile (and therfore downclocked) NVidia Titan based GPU with 2496 cores.
This isn't too hard to believe since they did offer the top end 680MX in the 2012 model, an NVidia SKU that didn't even exist until the launch of the iMac.
I think we'll see the same HD/SSD/Fusion options as the 2012, but hopefully the high end will get bumped to a 4TB HD.
I think for me though the deciding factor may be the LCD panel. If they opt for the 4+ generation old LG panel, I'm not sure I can bite. It's hard to think of spending that much money for a machine that has a display with inferior color gamut to my iPad 3. While I don't see increased resolution as a necessity, I do think they need to step up their game in the gamut department to compete with other professional level displays.
