I saw on macrumor's new iMac post regarding the update in a few days that it may contain AMD Radeon M380 - M395X discrete GPUs. Im not very familiar with AMD and was curious as to what the equivalent Nvidia card would be as far as performance? Particularly for gaming.
 
Just as a reference point, the M295X was in the same class as a GTX970M.
So, the M395X could be in the 980Ms ballpark.
The M390x could creep between 960M and 970M (more towards the latter.)
The M380 should be between a 950M and a 960M.

Just keep in mind that the switch to AMD had some technical reasons alongside with the financial ones: When it comes to parallel computing and the technologies for apps like FCP, Adobes Suite and so on, AMD is still king.
Of course, NVIDIA is gaining ground in this regard as well and might be more suited for gaming at Full HD resolution, but the bigger the resolution, the smaller the difference between AMD and NVIDIA.

Oh really?? i didn't think they were that on par. So as far as gaming goes the model with the 395X should do just as good as a 970m/980m?? aka any game you want, most on very high settings?

ah, good to know.

I don't know where you guys got these numbers from. There are only minor differences between the M395X and the M295X regarding performance, surpassing it by more than 10% would be rather rare. And from all the numbers I've seen so far, the M395x is much closer to the 970m than the 980m, of which neither is capable of running most newer games at or near 60 FPS, not even at FHD, let alone 1440p (not even mentioning 4 or 5k).

The M395X is ok, as long as you don't have too high expectations. It will get outperformed by rather mediocre desktop GPUs like a GTX960. Except for some very demanding games you should be fine @1080p or 1440p, as long as you are willing to reduce settings when needed.
The only games I'm able to play at 5k are those rather old ones, like HL2.

It is a decent upper class mobile GPU, and most of all, it is capable of driving 2 5k displays. I wouldn't be surprised if that's the main reason why they went with AMD GPUs for all the 5k iMacs so far.

Every time someone used the "@" symbol in conjunction with "1080p" resolution... I get tagged in their post... LOL!

i disagree on your comments about the 970m. I have that in my new gaming laptop and i run any new AAA title on High(est) settings (battlefront, etc) with excellent frame rate at 1080p

I guess it depends on how you define "excellent frame rate". Personally, I consider anything above 30 FPS quite acceptable (though not ideal), depending on game type of course. I believe you that you get such frame rates with many games. But even then, only at 1080p. That's more than fine on a laptop, but on a 5k 27" screen, I would like to get at least 1440p.
 
I'll get you frame rate numbers later on today. I suppose as far as resolution on a screen that big, but games are only just starting to get legitimate 4K support anywho
