NVIDIA Announces New "World's Fastest" Notebook GPU Discussion

Today NVIDIA launched their newest and fastest gaming GPU, the GTX 480M. This chip has a lot to offer for notebooks, including a dedicated Tesselation engine for “up to 5x more performance than any other GPU”. NVIDIA claims it currently beats anything else currently on the market, and all notebook manufacturers have to do to set new performance records is to build a system around this GPU.

This is not as easy a tasks as it sounds. What's the TDP on this thing? The Eurocom rumor said 100W and that sounds fairly close given the desktop cards.

 

I'm curious about both the power input rating as well as the TDP. Doesn't sound like even the beefiest of notebooks will be able to SLI these things. Is this a move towards single "large" chips running notebooks as well?

Remember something very important as more news comes on this chip. Memory and the interfaces to them take a lot of power and the large bus will give off heat. AMD lowered the HD 5870 to a 128 bit interface to meet the power requirements, and often you see that in mobile chips because large memory interfaces eat up power and put out heat.

Additionally GDDR5 uses up juice too. It's not shocker when a 512mb mobile chip outlasts the same chip with a 1gb memory just on the power used by the memory alone (assuming the same bus size on both). So you have two things that will up the useage of this chip beyond the chip itself, the bus (which is double the bandwidth of the HD 5870 btw) and the option to use "up to" 2gb of GDDR5. Even if they only outfit it with 1GB, the bus size is going to be a monster.

What's funny is this thing looks like it might be competetive with Crossfire HD 5870's... I'm not sure on that, but it's got a lot of shader units, and it's certainly got double the memory bandwidth of a single HD 5870.

If the M17x or Clevo manage somehow to SLI these beasts, sign me up

 

wow 352 cuda cores! i thought it would be way less than that. This seems like a big step for nvidia, considering they're flagship is almost trippling the amount of cores. Lets hope it doesnt cause laptops to explode!

 

yes me too, i want this thing in SLI

 

^ don't we all? without breaking my back, bank it's not really possible though.



Kinda wondering what 380M is, saw that too a while ago.

Unlike the 8800M GTX era though, Ati's got worthy alternative that runs in CF for alot less money, that runs cooler, eats less battery. Will have to see how this performs though. Should be possible to get 280M GTX sli level of performance with OC'ing - those core are on the low side though.

Also need to know if anyone is actually going to do this in Sli, 200W of TDP in graphics alone, is quite a mouthful...

 

It's a little early to speculate, but based on the number of cores, comments about performance, and what little information there is about the TDP, but I think it's safe to assume that we'll only see this in the largest 17-inch and larger gaming notebooks.

It's "possible" we'll see this in 15-inch gaming systems, but if that is the case then we'd probably be talking about VERY thick notebooks.

 

Whell the XMG8.c only offers a single 480m, so its safe to assume youre correct..

 

The Quadro FX 3800M is 100W TDP, so it's not a stretch for this to also be at the same TDP. Then again, at idle, it should be pretty efficient if it's similar to its desktop counterpart.

 

I find it humorous that Nvidia had to cut the GPU clock speed in HALF from its desktop counterpart just to get the TDP down to 100W, which is still a crapton.

 

Here is a review of the GTX 465 which is similar to the 480M (352 shaders, 256-bit GDDR5 memory) except for the fact that it is clocked at 608/802/1215 whereas the 480M is at 425/600/850. The 480M should have roughly 70% of the GTX 465's performance so it will probably outdo the MR 5870, but not by much.

 

The GTX 480M is 425/850/1200, core/shader/memory

 

That review was not good, I really hope it's nothing like the 465GTX

 

I was quoting the GPU-Z screenshot in core/memory/shader (GPU-Z doesn't count the doubling of the memory). In your terminology, the GTX 465 is 608/1125/1604 core/shader/memory. It doesn't change anything -- the 480M's performance is still about 70% of the 465's.

 

Why am I suddenly not to impressed by that?
We need a review of one bad to get the questions answered.

 

really? compared to the 58xx series Fermi FAILS when it comes to performance per watt big time. maybe these mobile ones will be different but I doubt it.

wow, the first time in years nvidia has put out a 'new' GPU for there mobile line....

 

Well, 465 GTX perform as good as a 5870 desktop in directx 11 games with heavy tessellation though. 480M might not be too big of an improvement over 5870MR in dx10 and below games, but I suspect the performance difference in dx11 games will be quite large. Though the price of 480M is still a bit on the steep side.

Performance per watt is meaningless, it's either you have the performance or you don't, in the case of desktop replacement notebooks, battery power is nothing.

 

I'd like to see this in an all-in-one computer. Hp touchsmart or better yet, the next iMac?

 

Fat chance...

 

Bad news from Italy. This is a (translated) e-mail I've just recieved from Santech, the main italian Clevo reseller:

Dear xxxxx, we're not planning to introduce the GTX on the N56 (their name for the Clevo W860CU 15.6") because:

1. the card is way too hot and the dissipation system of the N56 might not be enough;

2. the price of this new VGA is exagerately high (more than twice) if we compare it with the ATI M.R. HD 5870, even though the nVidia doesn't have twice the performance of the ATI.

Cheers.
SANTECH

 

In any case heavy graphics gaming is never done on the go. The only question is if there will be a need of an improved cooling solution or actual designs are enough to handle it.

 

NVIDIA Announces GTX 480M: Mobile Fermi Coming Soon - AnandTech :: Your Source for Hardware Analysis and News

Correct specs:

Mobile 480

352 cores
425mhz core
850mhz shaders
600mhz ram (GDDR5, 256bit) (2400 QDR)

100 Watts (GPU + Mem)

(confirmed with Nvidia)

280m = 75W

 

Response from my reseller is;
You cannot upgrade your D900F from GTX 280M/285M to the GTX 480M, since you need a whole new chassis, internal power system, power adapter and a new MXM slot, which supports the 100w tdp for this card (the previos one does not).
The same goes for the X8100.
So basicaly, if you want this gpu, you have to buy a new laptop. With the price of the card (1100€ - more than twice the price of mobility 5870) nvidia is already pushing it, but buying a new (basically the same) laptop and throwing away a heap more of money just for this - nvidia really screwed up with fermi.

 

Have to admit that the spec of the card is exceeding expectations, but the price is just outrageous.

 

If it were just the price of the gpu itself.. but to have to buy a whole new laptop is just ludicrous.

 

Lets hope they would have a 75W GTX 460M. But then might as well get the a 5870 MR.

TBH these cards are a bit overkill for CS 1.6. Consider I don't play other games, it'd be wasted on me. Not to mention student wallet hardly could finance one, let alone Sli! Better off getting a desktop myself.

By the time these come down in price, Sandy Bridge and AMD's 6XX0 MR will be out! Those two products both hopefully would put more emphasis on power efficiency!

 

It seems the ATI 58xx is the most sensible design for a notebook.
