Hi.

Between NV GT540M and AMD 6730M, which one is more stable / reliable / less heat and noise?

I am considering Asus laptop. Not sure which GPU to choose. Been searching info online. NV GT540M performance is not too poor compare to AMD 6730M and cheaper. However there are people complaining regarding Optimus.

Apparently NV GT540M consume more power than AMD 6730M. Does it means that NV GT540M will be hotter compare to AMD 6730M?

Hope that all Sifu can guide me.

Thanks.

Hi. regarding 6730m, according to website, it is basically similar to 5730m (the architecture a bit different, Turks and Redwood)

I found one review of Asus laptop with both NV GT540m and AMD 5730m.

They run both laptop using Furmark for one hour. They use software to tell the CPU, GPU and HDD temperature. Besides they also use Fluke heat camera to measure the keyboard temperature.

Software result:
GPU = NV GT540m / AMD 5730m
CPU Temp : 75C / 67C
GPU Temp : 87C / 55C
HDD Temp : 30C / 38C

Apparently the software result tell us AMD 5730m has lower temperature.

However using the Fluke heat camera to measure the heat at the keyboard, it shows that the laptop with 5730m has the heat more "concentrated" compare to GT540m at the keyboard. Which also means user will feel more heat at the keyboard with 5730m.

In this case, which one will be better and last longer? 5730m? (sacrifice user experience)?
