my opinion, should be less heat generated, since this A6X is totally new chip with more efficient and more powerful.

so, if this new chip can handle all power hungry apps without pushing to max power, should be less heat generated. and i heard this A6 is more better fabrication , like 32nm . correct me if im wrong.

what is exactly the reasons ipad 3rd gen heated up so much?because pushed too hard the GPU for the retina display?
*
is because those massive screen resolution. 2048-by-1536 quite huge, more than fullHD. apple push the A5X with quad core GPU PowerVR SGX535.
while for ipad4 use A6X with quad core PowerVR SGX 554, which more powerful and more efficient. should be less heat generated.

check with http://en.wikipedia.org/wiki/PowerVR

Model Year Die Size (mm2)[1] Config core[2] Fillrate (@ 200 MHz) Bus width (bit) API (version) GFLOPS(@ 200 MHz)
SGX535 Nov 2007 65 nm 2/2 14 500 64 9.0L 2.1 2.0 1.6
SGX554 Dec 2010 1-16 8.7@45/32 nm 8/2 68 1000 64 9.0 2.1 1.1 12.8

compare the die size and the power it produce.

According to anandtech ipad 4 still run hot just like ipad 3 while gaming or while the processor is really being pushed.
However, the warm issue is not that obvious at normal usage like web browsing.

I'm still thinking this ipad 4 worth my money to upgrade or not  hmm.gif  I need some1 to compare the battery life between ipad 3 and ipad 4  tongue.gif

i saw spec and comparing at gsmarena before, it mention have same battery life. not sure on real life tho.
