Gtx 675mx or 680m? - Page 3

I own an m17x with 7970m. Think the 7970m is junk.
But you gotta understand that AMD GCN is a lot better at certain things, as compared to CUDA.

It's alot better for hybrid use, like using it for general purpose graphics. IE Sony Vegas 11 GPU accelerated video editing, or AutoCAD/AutoDesk, GCN is far more efficient at multiscreen because AMD gpu's have been doing multiscreen for much longer than Nvidia. AMD GPU's also run a fair bit cooler, especially the mobile chips. which means you'll have a better phyisical marjin for overclocking since you wont stress you cooling system as much if you do overclock. Nvidia's GPU Boost is limited by heat. Those chips run hot, so if you're going to overclock one in a laptop, you better have AT LEAST Artic MX-2, or ICDiamond thermal compounds.

There's reasons to buy Nvidia(physX, OCing range, 3D, game compatability) And theres reasons to buy AMD(multiscreen, cooler temps, wider compatability range, gaming gpu workstation gpu crossover)

Nvidia GPUs (Kepler: 670mx, 675mx, 680m) run cooler than the 7970m (not that I'm worried about my GPU ever overheating), but you're right about the rest.

What about 680mx?

Eh just going off the real world reports from the alienware M17X annd M18X. The people with the HD7970M are reporting mid 60C, but the GTX 680Ms are hitting mid 70Cs.

Excuse me.
I just realized i have it assbackwards.

MY BAD.

Its the other way around....
sorry @_@

Either way those temps are low for laptop GPU's. the 8800 and 9800 laptop series hit 85C or higher while gaming frequently.

The GTX 670MX, 675MX and 680M are ALL Kepler. tongue.gif

And the differences between the 675MX and the 680M aren't as huge as one might be led to believe. Yeah there's a sizable difference between the GTX 660 and GTX 670, but it's not THAT huge. The 675MX has enough firepower and a large enough memory bus to just set the start line for ya.

Just push that core and memory clocks up and watch the numbers fly off the chart. thumb.gif The 675MX is definitely an amazing card for the laptops. It's one of the more largely disregarded cards at that.

I confused it with the GTX670M , no need to tell me twice. I read it the first time on the previous page. thumb.gif

Hi, I own a P150em since jan 2013.
I bought it with a 675mx and overclocked it, it's almost as fast as a 680m now.
3Dmark11 score: 5825


It is realy impressive.... 29-7-2013 12-51-56.png 121k .png file

Hope I helped....

Thread is over two months old.

Issue was solved back then.
