More information on third generation Apple iPad "overheating"

Laptopmag conducted temperature tests on several tablets:
  • Apple iPad 2 - A5 (dual core processor and dual core SGX543MP2 graphics processing unit)
  • Third generation Apple iPad - A5x (dual core processor and quad core SGX543MP4 graphics processing unit)
  • Asus Transformer Prime - Nvidia Tegra 3 (quad core processor, 12-core GeForce GPU)
  • Motorola XYBOARD 8.2 - TI OMAP 4430 (dual core processor, PowerVR540 graphics)

Heat was measure after 15 minutes of video streaming and gaming. Heat was also measured in after loading 50 websites. The results were as follows:
  • Apple iPad 2 -  29 °C to 33 °C
  • Third generation Apple iPad - 33 °C to 38 °C
  • Asus Transformer Prime -30 °C to 37 °C
  • Motorola XYBOARD 8.2 - 32 °C to 33 °C 

What was surprising is that the third generation iPad runs hotter while browsing the web, than the iPad 2 would while doing intensive gaming.

We do not know what the ambient temps were at the Laptopmag labs. 

Consumer Reports did its own test running Infinity Blade on the third generation iPad.

Ambient Room Temperature - 22 °C
iPad 2 temperature after running Infinity Blade for 45 minutes (WiFi on) - 38 °C
Third generation iPad temperature after running Infinity Blade for 45 minutes (WiFi on 4G off) - 45 °C

As I write this, I checked the Ambient Temperature in Metro Manila today. On a cloudy day it is 31 °C.

We will follow this issue.
