"Notice that the component on the left uses both fans and has two-thirds the total number of heat pipes" Ummmmm if I'm looking at the picture correctly the GPU and the majority of the heat pipes are on the Right, you may want to retype that.

The funny thing is, AMD actually DID use the naming scheme you like in their LAST generation of mobile GPU's. The Mobility 4850 matched the standard 4850's number of stream processors, albeit with lower clock speeds. Same with the Mobility 4870 and Mobility 4870x2.

They changed it in response to Nvidia's naming scheme, which is a shame. I liked the matching of desktop/laptop performance to names, too. :/

[citation][nom]Maziar[/nom]Great review.Before its launch,it was rumored that it will have a much higher power consumption than 5870M, but now it seems they are close[/citation]The difference of around 50W under full load is a big deal! Fortunately, you only SEE that difference under full GPU load.[citation][nom]shuffman37[/nom]"Notice that the component on the left uses both fans and has two-thirds the total number of heat pipes" Ummmmm if I'm looking at the picture correctly the GPU and the majority of the heat pipes are on the Right, you may want to retype that.[/citation]Excellent observation, thanks!

With that kind of money i can get both, a good gaming desktop and a decent gaming laptop (with 5870M). Oh well...
But its nice to see nVidia catching up to ATI... Let the price wars begin so i canget my second 5850 ;-)

Many people were praising the Mobility Radeon HD5870 for its relatively low power consumption, especially in comparison to the spec sheet for the GTX480M, which described Nvidia's latest high end mobile part as having a TDP of 100W. In fact according to the spec sheets the Mobility HD5870 uses significantly less power then even the GTX285M at full load, 50W in comparison to 75W. However, it quickly became apparent that something wasn't adding up.

http://www.tomshardware.com/reviews/avadirect-clevo-w860cu-mobility-radeon-hd-5870,2615-11.html

What many of the people who were bashing the TDP's of the GTX285M and GTX480M didn't understand was that ATI and Nvidia calculate TDP differently. ATI only figures in the power draw of the GPU itself, while Nvidia measures the entire board including memory. So direct comparisons based solely on the numbers provided by the spec sheets won't accurately represent real-world differences in power consumption. In many cases the actual power draw of these mobile parts is much closer then the official spec sheets would have you believe.

Price is being overlooked here.
GTX 285M is 75$ more than Mobility 5870 so I believe I can buy 2 5870 for the price of one 480M.

lol at the price. I don't think anyone is going to pay twice as much for a laptop that has a 10% performance advantage. Also I don't think AVADirect is going to show us the laptop symbolic of the GTX480M. Their HD5870 Mobility model is not that good compared to ASUS, ACERs, and MSI's models. It will probably be from these three that will make a sellable laptop using the GTX480M.
 
The benchmarks are a bit misleading. The 1280X720 eschew the tests. On the tests dirt2 DX9 the mobile 5870 wins big in the 2 highest resolutions. DX11 as stated in other reviews only matters if you stop and notice the fields. In Stalker again at the 2 highest resolutions in DX11 the mobile 5870 wins. The ultra high in Stalker shouldn't count as the fps isnt playable at these settings.

Noted that the 480M is given top in the Call of Duty: Modern Warfare 2 while losing to the 285M in 1280X720. Why wasn't the 5870M's Dirt 2 and Stalker high resolution wins Moved up the graph? On Dirt 2 ultra the 480M loss in both high end DX9 but still tops the 5870M. At high quality 1920X1080 the 5870M beats the 285M. With Stalker hgih perset DX11 the 5870M beats the 480M is both high resolutions but again its not moved up the graph. The graphs have no standard and seems to favor the Nvidia at any advantage.

I can only guess this is a pro Nvidia article. The below quote is incorrect as the 5870 wins in the 2 high resolutions DX11 tests. The quote is only correct if only the 1280X720 test is used.

when using the above quality settings, and still manages to outpace the Mobility Radeon HD 5870 in DX11 mode.

Too much heat and although the laptop may game great for a while it will soon end up being dead even with a laptop cooler.
I'll stick with a cooler desktop because if the graphics card does eventually die a heat related death (rare) at least I could replace that part.

Now, if we could just get AMD and Nvidia to agree to name their flagship mobile GPUs after the mainstream desktop cards they most closely resemble...
+1
I'm surprised someone hasn't tried to sue them for that yet...

DX11 as stated in other reviews only matters if you stop and notice the fields.[/citation]That's why the OTHER reviews are misleading. I don't know anyone who actually goes through the effort of MANUALLY CONFIGURING DX9 mode for DiRT2 in REAL LIFE. Thus, you must come here to get an honest evaluation.[citation][nom]elbert[/nom]In Stalker again at the 2 highest resolutions in DX11 the mobile 5870 wins. The ultra high in Stalker shouldn't count as the fps isnt playable at these settings.[/citation]The article mentions lots of places where the results don't really matter, so you're still getting the straight scoop.[citation][nom]elbert[/nom]Noted that the 480M is given top in the Call of Duty: Modern Warfare 2 while losing to the 285M in 1280X720.

You only complain when that arrangement doesn't suit your personal goals?[citation][nom]elbert[/nom]The graphs have no standard and seems to favor the Nvidia at any advantage.
