So the 660m is Kepler, and the 670m is based on Fermi.
I'm looking to buy the new ASUS G75VW, and I'm not sure which one I should grab - 660m or 670m?
660m produces less heat, gives more battery life and is new tech. The 670m should give better performance, produce more heat and reduce the battery life compared to the 660m.

I need some insight from someone who knows for sure, someone who is knowledgeable. Which one should I grab for the ASUS G75VW? Could I just buy the 660m and OC it to stock 670m? I could do the same with 670m and get even better perfomance, no?

Sorry for the clutter, hope someone can give me an answer and settle this for me :p

what's the price difference?
notebookcheck doesn't have 670m reviews yet so i can't say for sure, but judging by the specs it should be about 10% better than the 660m.

Personally, i'd choose the 660m. It uses significantly less power and should be more overclockable than the 670m. Laptops with this kind of gpu power are hot and anything to get them cooler is welcome.

That said, you mentioned battery...
you can't game on battery, not at all. In fact most gaming laptops have around a 2 hour battery life without gaming. Everything is throttled on battery, and if you turned that off you get maybe half an hour out of it.

@plasmid
this is the 'm' series we are talking about. Yes they are out.

I'm not looking to game on battery haha, was just stating the facts :p
The 660m ASUS comes about NOK 1000 cheaper than the 670m ASUS, which is about £100. Yes, I live in Norway.
So I should go for the 660m and overclock it? I'm usually very indecisive when it comes to things I know little about, I almost need someone to tell me "get this one!" haha

yeah the 660m is definitely the better buy there.
I'm not sure if you should oc it though. Check temps when you get, laptops have a far smaller oc headroom than desktops.

I have a 580m which can play bf3 around high settings at 1920x1080. According to notebookcheck, the 580m about 28% better than the 660m. It was also insanely expensive ($700 usd) and i only got it cause i was playing at 1920x1080. What res are you playing at?

The ASUS G75 Im looking to buy has a Full HD screen, so I'll be playing on that. Mostly WoW, SC2, BF3, Skyrim and Diablo when that comes out. I used to play BF3 all the time on PS3, and I reckon even medium on a computer is the same or even better than the PS3, graphic-wise.

There is a guy who's currently playing with this exact computer and the 660m, he testing it by overclocking it and posting results at notebookreviews. These are his results so far http://3dmark.com/3dm11/3313741;jsessionid=vzdbegu2332w1eqki2ztjp221

I have no chance of decoding this, so I don't know if this is good or not.

...next time you should probably post in the mobile forum just so we don't get so many people thinking you're talking about desktop cards.

do you have any other links to this guy's experiments? a PCmark score doesn't say too much without context.

Oh, I'm sorry! Thought I posted in the right section when it said "Graphics Cards".
I don't know, but here is the whole thread: http://forum.notebookreview.com/asus-reviews-owners-lounges/659534-asus-g75vw-ivy-bridge-660m-review-13.html

this section is fine. your question is between the two topics so either place makes sense. It's just that posting in the mobile section stops some people getting confused.

Haha, I'm starting to recognise your name amuffin :p
I'm gonna follow your advice and go with the 660m. Means I'm gonna have to wait one more week, but whatever!

What kind of FPS do you think the 660m can pull in Skyrim, Diablo, BF3, Crysis etc, on medium-high settings? Will it run em at ultra at all?

bf3 will run lower with an average of less than 30fps on ultra. Online that is. Probally closer to 20-25fps. That using my 580m as a baseline and subtracting 25ish percent. Turning it down to medium should help a lot. I'm think around 45 avg fps but i could be wrong.

Diablo should run on ultra or very close. The only problem i have is if i turn up the sound channels, but i think this is just a glitch in the beta.

Skyrim should run on high with 45-50fps.

i'm assuming this is with a mobile i7 (and not an i5 which is dual core).

I was wrong in saying that the 660m version was £100 cheaper, sort of. The 670m version actually comes with 2 GB more RAM and 250 GB more HDD space. The 660m version is still £100 cheaper, but I also get less RAM and less storage space with it.
 
The G75VW has a few versions. He is stalking about the actual laptop ram, the 660M version is ~$100 cheaper and has 8gb of ram with 500GB hdd, while there is another version with the 670M that has 12gb of ram and a 750GB hdd.

yeah I was talking about laptop ram not vram. What gpu has 6 or 8GB?

He said 2GB though so I was kind of confused since lga 1155 usually has ram in increments of 4 since it supports dual channel. (i suppose the 12GB is 3x4GB though)

I suppose I should've actually looked up the laptop... but yeah, didn't feel like it at the time.

anyway, if it's 8 to 12 GB and 250GB, I'd still say it isn't worth it. You don't need more than 8GB and the 250GB isn't much. That laptop also has two hdd slots so you can always add more storage space. (unless you are using an ssd as well)
