Gtx680m vs 7970m in Crysis 3

post #1 of 11
Thread Starter 
Considering getting a P170 notebook to take my gaming on the go.

Would love to be able to play crysis 3, tomb raider, hitman absolution, bioshock infinite etc.. All the latest games that I own but don't get to play while I work away, as my MacBook retina can't handle all the games and not enough hdd space anyway.

So asking anyone with the above cards, can you please share personal results in any of those titles? Can't find any benches on google.

I'm torn between getting one now, or waiting for the 700m series from nvidia. Rumoured specs seem real promising.

Cheers

Im also interested in this, how does the 680m compare to a standard 680 2GB model with no overclocking?

From what I've found out, seems the 680m is similar in spec to a desktop 670 but with lower clocks and much lower memory bandwidth due to the lower clocks.

Early benches show the 7970m and 680m very close in performance.

Wondering if anyone has first hand knowledge?

I've only recently bought a new Sager myself and researched the options for about two weeks, and from what I've read the 7970m consumes more power, doesn't overclock as well, and has horrendous driver issues. Cruise around notebookreview.com and you'll find the information you need.

Thanks for response

I did read some of the same info somewhere, but a lot of it was dated like oct-nov 2012 which means nothing to me right now. But then realistically we've been in this game long enough, spose what could possibly change in those few months haha

CCC 13.1 driver fixed a lot of bugs, and the 7970m is $200 cheaper, at least on XoticPC website for the NP9150. According to Notebookcheck, the 680m is somewhat faster than the 7970m. But are you willing to pay an extra $200?

AMD stated that they'll be releasing a driver that gives the user the choice if they want increased latency (due to extra buffering), or potential stuttering, on June or July.

Yeah it's almost $200 cheaper here too. But you gotta weigh in VRAM and features too. I mod the crap out of skyrim. And I love physx in borderlands haha. I know it sounds like I'm looking for a reason to go nvidia, but really I'm looking for a reason not to and I can't find it. Which is a shame coz until the desktop 400 series, I was always ati.

If you're gonna overclock, the 680M will toast the 7970M. Just make sure the memory gets a nice boost if you do so.

However, if you're lookin' to save a bit of cash but still want good performance, the 670MX overclocks like a monster too. Heck most 670MXs manage to match a 7970M, after overclocking to the max, if not surpassing the AMD GPU. I'm planning on grabbing one myself later on down the road. biggrin.gif

Hmm didnt think of that. I was considering the 675mx .. More VRAM for skyrim plus pretty sure it's on the smaller die, meaning cooler and less lower draw.

Is it safe oc'ing laptop gpus that much though? Would think in such small form factor, would cook them

haha screw it, went with the 680m. will let you know how it goes. the 700 series only just got announced in the mid range, so high end probably not until end of the year or something. plenty of time to use this now and upgrade if its worth it later.

looking forward to being able to mod skyrim on the move, and finally keep up with my gaming while working away.
