Mobile graphics card selection help

post #1 of 7
Thread Starter 
I am planning on buying a new laptop in April as a desktop replacement, I have already picked out the Sager NP8150. The only thing I have left to select is the GPU. I don't have much experience with mobile Graphics cards so I need a little help. I am limited to the nvidia 460m, 485m and GT 540m. I listed what I want out of my laptop below, ranked as #1 is the most important.

1. I don't want there to be major thermal issues, since this is a laptop, I don't want it to combust on me while gaming, I would like it to also be as cool as possible while not gaming.

2. I like to max my graphics whenever possible (I will be playing things like; Elder scrolls 5 and diablo 3, and hopefully games for the next 3-5 years.

3. Since this is a desktop replacement, I will probably run it without the battery most of the time, so power consumption is the least of my concern.


other suggestions for laptops and GPUs are welcome! Thanks.

1. In my opinion without seing a review of that laptop there's no way for you to know if it's gonna be hot or not, while gaming or idle. The power consumption of the GPU is important in this, but not as much as the fan settings and chassis design. In my opinion while gaming, any GPU you'd choose, it would still be wise to buy a notebook cooler as Nvidia cards have reliability issues when not cooled properly. On battery if you can disable the discrete GFX card, the lappy is gonna be as cool as it can be.
2. 485>460m>>540m for a balanced tig maybe the 460M stikes the best balance, being the GTS 450 GPU it can play @720p everything with good details; the 485m could be a tad too hot as it has a full GTX 460 GPU (100W+) but also the best performance; it could play all you posted @1080p; the 540m is a rebranded 445m which is a GPU similar to ~9600GT but lower clock speed.
3. Power consumption usually means heat or noise or both.

The 485, is a beast... an very expensive beast. It performs just shy of a stock desktop GTX460. It runs on par with the 460m in SLI. It certainly has the potential to be warm, but the cooling on Clevos are top notch for a laptop.

Here is a review of a similar Clevo with a 485m.

As gaming for 3-5 years... I can see 3 years @ medium, but desktops get replaced/upgraded in 3-5 years.

GTX 460M is the balance choice. Still good in terms of power consumption but provide good gaming experience.
Anyway, if you were looking for 3-5 years... I can only say low to minimum detail in next 3 years at 720p. GPU improvement these days are great. You can clearly see how ATI/AMD leap from Radeon HD 4000 to 5000 series. And how NVIDIA from 400 to 500 series. Significant improvement!
Newer games will optimize new GPU performance.
Even for desktop PC, you should realize how great GeForce GTX 280 and Radeon HD 4870 when they launched.
But now? It's just from 2008 to 2011. In 3 years, the former top-of-the-line Graphic Cards from NVIDIA and ATI/AMD at 2008 can only handle medium details for most new games. The development in 3 years are very awesome.

All these comments are a huge help. I think I have almost narrowed it down. The final question is whether nVIDIA is planning on releasing an new line in Q1 or Q2 this year, Since I have to wait until April for this laptop anyways, I don't mind waiting a little longer for a new card to be released. Have there been any rumors or confirmations going around?

They have barely introduced the 485m, and they have introduced it with the full 384 shaders of the GF104. The logical successor would be the GF114 core (GTX 560Ti), but while on the desktop they can cool 150W+ GPUs, on laptops it's not possible. Imho the desktop GTX 5xx generation isn't much better than the equivalent GTX 4xx (at the same wattage) and it's unlikely that on the mobile front it would be any different.

So, my take is that NV will not introduce anything new until fall and even if it did it wouldn't be much superior to the 485m. It should be the same for the lower price segments.
