Best dedicated graphic card

[Serban]

In present or in the close future is there any better dedicated graphic card than 680MX?

You are talking about mobile chips? The NVIDIA GeForce GTX 780M is currently the fastest mobile card, AFAIK....

The 780m may find its way into a revised iMac down the line.

The 780m may find its way into a revised iMac down the line.

Another member & I went chasing down the specs and benchmarks just last week on this. The 680MX in the iMac is specialized just for the iMac. The 780m is "mainstream". It gets about 2% more performance in benchmarks, has the same # of cuda cores and everything. It's virtually the same card. The only chance a new iMac would have a better card is if Apple gets a specialized card again which isn't out of the question. They surprised everyone with the 680MX & I'd wager they'd do it again for the new iMac as the 780M just isn't that much of a spec bump.

For the first time nVidia makes a special card just for Mac computer, the 680MX. No laptop will ever uses it (now 7xxM is out, what's the point of going back with 6) It's not mobile cards (120watt TDP, folks) .. but not exactly desktop card either (significantly weaker than real 680).

It's hybrid, it works quite well and I hope Apple keep getting this modified graphic chip in the future.
So far my late 2012 iMac has been great. Not so much with my old 2011 . T'was terrible machine

so in the next imac upgrade we will se 780MX ? probably with the same 2GB vRAM

based on that seems a little better

I'd say most likely.

On paper it looks better. 700 series 'current' graphics card. Larger number = "upgrade".

but in practice it'll be almost the same thing.
