Asus G50V-T940BFJGAW or Asus N51Tp?

post #1 of 7
Thread Starter 
Greetings everyone!

I wish to buy a notebook, and I have managed to narrow down my list of potential suspects

The requirements of the notebook that I wish to own are:
Medium-High graphic performance
Relatively medium to long battery life.
Fast CPU.
15,4-16 inch. I don't want a bulky notebook
The rest are not that important. Ram Preferably 4 GB DDR II at 800
At least 320 GB space.

The notebook will be used for various purposes including games and 3d modelling.

Based on this information I have narrowed my list down to two computers.

The Asus G50V-T940BFJGAW and Asus N51T

Both are 15 inch notebooks.

The G50V is advertised as a gaming notebook with 640GB of space, Intel Core 2 T9400. And a Geforce 9700M GT with 512 Ram.

This was my idea to buy first until I found the Asus N51T.

This notebook is advertised as a conventional notebook, with 320GB of space, AMD Turion 64 2X ZM-84 and ATI Radeon HD 4650 with 1GB of ram.

I did some research regarding the video card and CPU.

http://www.notebookcheck.net/AMD-ATI...0.13883.0.html

This website indicates that the average 3D mark 2006 score of the ATI card is 400 points higher than of the 9700M GTs. Thus, The ATI reaching 6671 points and Nvidia 6242 points. My main concern is however power usage.

The ATI uses 35 Watts while Nvidia uses 45. Thus making the ATI slighty better on the battery.

The main decision or reason for my dilemma however is the CPU.

Using :http://www.cpubenchmark.net/cpu_list.php
as a reference

AMD Turion 64 2X ZM-84 scored 1144 and 183 points. The first value the higher the better, the second the lower the better.

Now the Intel Core2 Duo P9500 @ 2.53GHz has significantly better marks 1763 and 100

My question comes down to.
Is it worth buying the G50V: with slightly lower GPU performance and with a very fast CPU

or

the N51Tp: with better video card, but with an AMD CPU being much worse.

Other factors that I consider important;

Very Important:
Battery Life, as I will be using the notebook away from home many times.

Heat Dispersion and cooling issues: I currenty own an Acer Aspire 5920G and this baby runs at a temperature of 100 degrees celsius when under heavy load. If i don't watch myself this notebook can sterilize me!

I read that G50V has a very good cooling.
As for battery life they say that the G50V lasts for 2 Hours with conventional battery and with a better one up to 4 hrs.

Unfortunately I have no information about the N51Tp. Nothing on battery life or heat dispersion and cooling.

Any suggestions, ideas, maybe someone can recommend a different typoe of notebook? Although I have to warn you I am in Ukraine, and the coice of notebooks is limited here. I found these 2 here so they are fine.

I am waiting on ideas. Perhaps if any of you have any of these notebooks, feedback would be extremely welcome!

Best regards

Why don't you just get the version of the N51 with an Intel CPU?

Not enough 3D computing

I thought about the ASUS N51Vf ,but here is the thing

This notebook comes with Nvidia Geforce 130 GT which has a performance of 5300 3D mark 06 points compared to ATI's 6641 points. To my knowledge that kind of difference means a serious a significant computational power difference.25% difference in speed to be exact. I wish to buy a notebook on a longer term that will be viable for use not just for a year or so. Thus if possible I want higher graphics power.

The most imortant however, I cannot find Battery life and Heat absorption and cooling efficiency for these models. Because for example I know that with an extended battery for the G50V, It lasts up to 4 hours.

Which brings me to the other dilemma:
I don't have any information about the socketing of the batteries on the B51Tp or N51Vf. For example my Acer has a fixed battery slot which means that only 4800mAH battery goes in it and you cannot buy the 7200mAH or even bigger. Even if you could, good luck getting that into a smaller slot. For me weight is less of importance than size.

In final words. I am willing to go for an extra battery in high performance notebooks that can last up to 4 lhours and for me weight is less of importance than size if possible.

Although I have to admit that the GT 130 uses 23 Watts only which is more power friendly compared to the ATI is 35 W or 9700GT's 45 W.

My only question is this: To what extent can you limit or lower power consumption of videocards in notebooks? Because if you can say, underclock a card for battery performance, my guess you will be lowering the power consumtion in a way. The question is I guess, how much you can lower the consumption of a Video card?

it depends on the drivers and if there's a secondary video adapter. For machines with Nvidia's Hybrid SLI, there's a secondary integrated video adapter that takes over when the higher-powered dedicated video card isn't needed. However, I don't know if the N51 uses Hybrid SLI. If it doesn't you're dependent on Nvidia's PowerMizer software to downclock the video card when it's not stressed.

Thx for the info.

I did some background check on this NVIDIA hybrid power technology:

http://www.notebookcheck.net/NVIDIA-...GT.9454.0.html

"In conjunction with the Nvidia 9100M G integrated graphics, the 9700M GT supports Hybrid-SLI (only HybridPower). HybridPower is a technique to choose between the integrated and dedicated graphics core, if performance or battery runtime is needed. This works only in Windows Vista. Up to now the user has to use a tool to switch between the GPUs. Later Nvidia wants to switch automatically in the drivers. GeForceBoost is not supported with this card, as there would be no performance gain.

Does this mean that the 9700M GT has this feature? If so, how effective it is? I know that the Consumption of of the 9700M GT is 45 Watts when used. How much would it approximately consume when in Power saving mode?

Also I know that a 9 cell battery exists for the G50V i just did not found it yet. Any ideas about the model number for this rig?

Regarding hybrid SLI, some notebooks have it, some don't. You have to check for the specific notebook to see if it's there.

The limiting or lowering of performance can be done using a utility that's in almost all ASUS laptops... Power4Gear can do this for you so. This is really meant to save batter power by shutting down non-essential running hardware...
