Is it worth the extra money or is it only more memory on the gtx780m?
Main reason is for gaming.
 
get the 780 w 4gb .. about as powerful as a dekstop 680gtx .. way faster then the 775.
If main reason is gaming then 780 no question
 
780m is based on the same core as 680/770, just clocked lower, it's not as powerful as these but it's not too far behind either.
 
I'm not sure about your facts!

680GTX = 5705..
780M = 4200

I also took a look and it seems the 680MX from the 2012 model beats out the 780M? I am highly considering a refurb 2012 - I will be using ethernet so I don't really need wireless AC. The only other difference would be CPU which of course 2013 would be better.

it depends on the options you want.

2013:
+ fusion drive is faster (1.5x)
+ cpu is faster
+ higher resale value
- cost more

2012
+ cheaper
- resale value will be lower in you upgrade often

That table shows the 780M against the GTX680 (note NOT the M version in the 2012 iMac) - of course the 680 GTX will be better than the 780M as the 780 will have its clocks, power and cores lowered.

Perhaps finding a comparison of the 680M would be more telling :)

The second post in this thread said it was comparable to the desktop version, which it is not. But even still, the 780M is rated lower than the 680MX in the top of the line 2012 model.

the original post I quoted referred to a desktop GTX680.. I was setting facts straight about that..
 
I think when the actual unit in the new iMac can be seen (thus checking its clocks etc) it will be interesting for sure. On paper it should best the 680M used in the 2012 models. I can't really see Apple adding a lesser top end option.

There is a comparison of the two chips as listed from the NVidia Specs here

The 4GB from the 2GB will help in many situations. (thinking XPlane may be very much better as it loves texture memory) and I would think CUDA performance will leap.

Can't wait to see some real-life benchmarks

oops I could have worded that a bit better as I meant for my post to add some detail to the point you were making. :( slap
 
Good thing is the 780m supports 4.3 opengl. Last years release but perhaps mavericks has full support for 4.3 for that card which means more performance will be squeezed out of it hopefully.
 
I'm totally in the dark with regards to GFX performance but having just ordered a new Haswell iMac 3.4ghz i5 with the 4GB 780M GFX i would just like to know if it's powerful enough config to run future games like BF4 and intense games like Arma.

Its been a while since i PC gamed and i would like to know if this iMac is capable of it?

I assume it must be with these clock speeds and the GFX seems about 10% - 20% faster in FPS tests on a review i just read.

All geforce 5xx and higher support OpenGL 4.4

Edit: actually, all geforce 4xx also support GL 4.4 ;)

What about gtx680mx vs gtx780m?

Well, look for yourself

P.S. Guys, stop looking at PassMark for GPU benchmarks, its NOT ACCURATE!

Should i return and upgarde?

so i bought an iMac a week ago and got all the extra upgardes (i7 and 680mx and 500GB flash) is it worth my time to return it and buy the new ones?

Same here. Will it run BF4 and CoD Ghosts smoothly.

Last year's would too, but that depends on resolution * settings * your definition of smooth.

1440p * medium/high settings * 45-60FPS? Probably plausible (more so for COD than BF4).
