Hello All,

I usually upgrade every few years sell my current imac and buy the newest one. I currently own Late 2014 Imac 27 4.0 GHZ i7, 5k Retina with 16b Ram, 3 tb fusion, 2gb AMD m290x video card and applecare. Is there a noticeable difference in speed compared to the model I already have? Im debating whether i will notice a big difference anyone who has it or has made the jump any help would be great thanks.
 
I highly doubt you're going to notice any difference, at all. Especially with those specs. On paper it's about 5-10% increase in speed, if that. Which is fine, as that's the norm now days, but for a Haskell to Broadwell/Skylake transition, I absolutely would not bother.

i have the same 2014 5k imac with 16 gb ram i7 and m295x
i tested along side with my friend currents 395x imac, the differences is close to 0
only in black magic disc the ssd has higher write and read speeds
the boot is almost the same 13-14 sec
importing files 0 or 1 sec difference wtf?
copying files is a difference
the heat is somehow the same
the fan at 1200rpm is louder on the new one
 
It only makes a real difference in temperature / overheating. So if you are always on the limit and cpu / gpu will throttle it might be a benefit for you.

 
I have both models, there's no subjective speed difference. I only have the fastest i5 CPUs of the 2014 and 2015 models.

The only reasons I can think of why I would uppgrade from a 2014 to a 2015 model:
- you really don't care about the money
- you work in a field where color gamut is of great relevance. Under normal usage, the difference is quite subtle. I can see it when they are next to each other, but telling blindly whether you are looking at a 2014 or 15 panel is quite challenging. Some reviewers were raving about it, but I'm quite confident that they're just full of it (full of placebo that is)
- you use programs that benefit a lot from Skylake (which most programs don't)
- You do a lot of internal copying or between the internal SSD and external storage that supports speeds > 1GB/s (advantage basically irrelevant if you use a Fusion Drive)
- You greatly benefit from 64 GB of RAM (but forget about the higher frequency, the effective performance difference is very minor)
- You are one of those people who have severe heat/noise issues with the 2014 model (I didn't)

Then there are the new peripherals. The Trackpad is the only one I might consider upgrading. The mouse is basically the same, except that it has a built in battery now. Still the same unergonomic shape though, so I don't use it. The keyboard changed a bit but I use neither.
Regardless, if you care about the new peripherals, they can easily be bought alone.
