I just bought the ASUS G75VW as a laptop to double for gaming and a college computer. It has a 660m. On Notebookcheck, it lists the 660M as being near equal to the 5770 (My current desktop graphics card) is this true and can this thing perform on par with the 5770? I know that with these laptops you can easily overclock about 5-10% without worry. I did try to overclock this thing a bit and got a 3Dmark equivalent to a 670M Which yet again Notebookcheck says is about 15% better than the 5770.

The thing that I am worried about is not being able to decently play intensive games. As far as I'm concerned my 5770 has met this expectation and I want to know if my laptop is at least able to compete with that.

why not run your benchmarks on your 5770 and compare them to the benchmarks you get on the 660m and go from there? If the numbers are similar, then you have your answer. If the numbers are better, then you also have your answer.

i would say at the VERY least its on par with the 5770, my G73jh has a 5870, and that's two notebook models ago. mine has a gtx670 and it eats just about every game i can throw at it for breakfast, including the guild wars 2 beta, skyrim and bf3, and the gtx660 is technically better than the 670 (a fact that i found out after i bought mine) because of the kepler architecture which the 670 does not have, which uses up less power, builds up less heat, and once OC'd apparently blows it away.

the benchmarks might not be too good, as far as accuracy goes untill the new nvidia drivers come out, but for now, it runs bf3 fine which is really all you can ask for on a laptop.

Im not so sure about that, while looking through 3Dmarks on my laptop some people with OCd 670ms which I assume are also in either an MSI or ASUS G75 due to the other specs, get around 3800-3900 in the GPU 3d Mark while the 660m gets around 2900-3050 when OCd. I mean, im sure these 660ms could last longer under that pressure due to their less heat and power but still, the OCd 660m is equal to the stock 670m. HOWEVER this could all be a driver issue due to the 670m being a redone 570m with more power which already is supported while the 660m Keplers are new and different.

Also, a 5870M is different than a 5870, a 5870M would be less than 1/2 the power of a 5770. Desktop Cards are always more powerful than their mobile counterparts.

Also, is there a reason why the 650m performs better in Diablo 3 than the 660m. Or is that another driver related problem

Also, after running 3Dmark on my desktop, i got a 2500 score for the GPU while on stock speeds the 660m is at 2300. However, something I DID notice is that the 5770 displayed its full Core Clock at 850 MHz while my 660M displayed the core clock at 405MHz, so there may be something to this driver thing after all.

Running Skyrim here at Ultra details , texture mods , everying running great , so yea I think 660m its quite good , btw Im using nvidia new beta drivers and no problem so far .

How did you get those installed, mine claim that there is no compatible GPU

it was not compatible a few days ago , nvidia updated it , just download it again from the official geforce website http://www.geforce.com/drivers check under beta driver and remember selecting 64 bits system . thats it

yeah, right now the 660's tend to get somewhat crappy performance to what they should be capable of, this is due to driver problems. supposedly nvidia is working on a fix. hence the beta driver.

I recently got a G75 notebook with 660M graphics card, and was quite underwhelmed in my favorite game, Rise of Flight. My desktop uses a GTX460, which in Rise of Flight is limited by amount of memory. The new laptop with 660M has 2gb memory, plenty for the highest settings in ROF. Unfortunately it cannot run smoothly at those settings, even without anti aliasing. I am quite confused, since the 660M has both twice the memory and a newer processor with more horsepower than my desktop's old GTX460. Clearly something is hobbling its performance. Does anyone know what it is, and more importantly what I can do about it?

McAfee Antivirus appears to cause bad latency on G75 systems. Uninstall it if it's running on yours and retest.

There are some reports the Atheros WiFi driver that ships with this laptop may also cause latency. Uninstall it and test on Ethernet if the game requires an internet connection.

^this, also there are problems w/ the current driver for both the 660 and 670 which is not allowing it to hit its full potential, nvidia is working it out.

Ah, I WAS running Kaspersky at the time, but still, I feel like the performance of a 28nm GPU should be slightly higher. Im hoping at least a 2600 on 3dmark11

the desktop gtx 460 is still mocuh more powerful than the gtx 660m. check here: http://www.videocardbenchmark.net/gpu_list.php

just because they have the same number 460 /660 etc the desktop and laptop cards are not the same in power! and just because you have a newer generation laptop gpu, it doesn't mean its more powerful than the older generation desktop cpu.

Not really, you expect a ATI HD 7770 to outperform a 5770 which it does by about 30%. You would expect a card using 28nm Architecture would be able to outperform a card using 40nm especially since the 28nm one is just as expensive. I mean, i know laptop GPUs are usually less than amazing but these 28nm GPUs were supposed to be the new big step in graphics card performance. And i still think the drivers are holding it back

Another thought, GT 650M cards are getting the same if not even better at sometimes 3DMark Scores, if Nvidia is claiming GTX Cards offer a 40% performance boost over GT Cards I dont see it. In fact, from the latest specs it looks like the 650M has higher base clock speeds while the 660M boosts higher than it by about 50 MHz, however, apparently the 660M isn't utilizing the boost as its getting beat out by the lower class card.

In fact, i just got the new drivers and re-ran 3dmark11 with my GPU overclocked at +135 and +375 and got the highest score for the 660m on 3DMark11, a 3095 total with a 2853 Graphics score but the 650m clocked in at 3061 with a 3091 Graphics score, 2853 Graphics score for the 660m and 3091 with a 650m. That is not good

Is the 650M supposed to be able to perform just as well as the 660M? I remember nVidia distinctly saying GTX = 40% more power

Could it be a driver issue?

Well, considering that the 650m and the 660m are both new kepler chips, im not sure. But if it is, I would assume its because the 660m's resources aren't being used as efficiently as they should be. Since the 650m has a stock speed of 850MHz with a boost up to 900 MHz, while the 660m has a stock speed of 835MHz with a boost up to 950MHz. This should make the 660m Have a significant performance boost considering everything else about he two cards is the same.

However, just ran over the specs again, the 885 MHz Core Clock couples with the 2000MHz Memory clock should beat out the 5770. Looks like it is just a driver problem, hopefully its fixed soon.
