When you manage to transfer heat from a colder body to a warmer one without any outside intervention, let me know. I'll share the Nobel prize with you! ;)

Learn what heat sink and back-panel mean.
And the most common material for heat sinks is copper, as aluminium losses it's shape in excessive heat and some other facts that are pointless to tell you as you clearly don't have any idea about this things.

Nvidia shield tab is having 32 bit Tegra K1. Its not at all comparabale with Apple's 64 bit processor. Even though interestingly Tegra K1 32 bit beat Apple in few GPU tests. Apple should review its iPad Air 2 price, its clearly over priced and easily defeated by android devices while performance testing.

There you'll see that aluminium is most commonly used for heat sinks. Nobody ever tried to use plastic as a heat sink material. Gosh, are many of you like that?

You can't even have as good games on Android. I am not a fanboy of any company or OS. I use both, i have experienced gradual decrease in Android device's performance whereas Apple devices keep on rocking even after years.

The new Apple GPU is a lot better than K1 regarding performance. But consider this: the Shield tablet is more of a semi-console, with features you can't find anywhere else. GameStream, special game titles, etc. If one only cares for the pure performance, obviously the iPad2 is a better choice. Still it's like buying a Bugatti Veyron in a crowded city with bad traffic. It's still awesome, but I'd stick with a helicopter and use its full potential, rather than having something more expensive and more prestigious, just because it's technically better even if I can't use it.

Whit this you show how ignorant you are. Just head to wikipedia for the heat sink article to educate yourself a bit.
The termal conductivity of plastic is 0.23 W/(mxK) while for the aluminium is 204-250 W/(mxK), more or less a 1.000 higher(go to wikipedia to wiki/List_of_thermal_conductivities). That means the aluminium will cool 1.000 times faster than plastic.

so why is apple so much more expensive? and for a current flagships tablet shouldn't it a lot better than those old android tab? 64 bit K1 should then easily outclass this... plus the 32 bit K1 wasn't outclassed but its in the same class and lastly imagine what a company like Samsung could do with such raw power from the K1 put lightly apple doesn't stand a chance

I would definitely not say out classed. That's a very misleading title.
First of all let's look at T-rex. The Air scored 72 fps while Shield scored 65 fps. That's a difference of 7 FPS, a difference of about %1.
Manhattan, 32 fps vs 31 fps. A Difference of 1 fps? What about frame time variance? That's the real test that should be looked at, doesn't matter if the Air or the Shield gets the FPS if it can't keep it very steady.

First of all this measures the graphics performance.
It does not have direct reflectance on the cpu clock speed.
You don't know which gpu draws more power to make that same assumption.
And your reference of difference in screen resulting to resulted power is ridiculous.
Lastly an aluminum body retains more heat throughout the whole device where as it dissipates from the plastic faster.

You all discuss the 3 results posted by GSMarena, not the whole comparison.
iPad Air 2 is faster in some areas but with a much lower quality.
And another thing, if you really thing Apple beats Nvidia at gaming experience and quality, your are mistaken.
Not to even mention the price gap.....

I see a lot of confusion about what "off-screen" means. It means running the test at the native resolution of the device- 1080x1920(2.073.600 pixels) for Tegra Shield, and 1536x2048(3.145.728 pixels-51.7% more) for the iPad Air.
If the off-screen scores are the same, that means the iPad Air id 51.7% more powerful.
However this is not the whole story. Tegra runs at 2.5GHz, Apple A8X at 1.5GHz. This means that at the same clock speed, the A8 would just bury Tegra.
Now in real life, starting the devices "cold", the Tegra will heat up faster than the Apple A8X. With temperature increasing , the chip requires more power to run at the same frequency. More power(higher current) means higher temperature. It's a positive feed-back loop. When the maximum allowed temperature is reached, the chip must decrease the frequency or else in gets burned. To help with the temperature increase, a heat sink or active cooling must be provided for the chip. For the iPad, the aluminium case is a very good heat sink, while for Tegra Shield or Nexus 9, the plastic case is a very bad heat sink.
So if you run the Tegra chip for 30 mins, probably the frequency will be degreased very much, and the performance the same. For the iPad, it might be that the temperature never reaches the maximum allowed value, so it can run at the same speed indefinitely.
So for the people with this knowledge, the choice is clear.
