IPad Po 9.7 getting Hot fast with apps such as videogames

[TrueBlou]

Getting hot, or warm as we've all got differing opinions on which is which, is pretty much expected if you're pushing the chipset.

The Pros have much faster CPU and Graphics chips so they will get hotter than previous generations. And as someone already said the 9.7" will fare worse than the 12.9".

But if you're really worried about it a quick trip to the Genius Bar will alleviate any worries.

I use mine to keep my beer chilled.

Your comments are always so random, yet somehow related to the topic at hand. I love them!

Arstechnica apparently use a special build of Geekbench that allows them to do thermal tests (and have as I mentioned included results from it in other iDevice hardware tests), but it doesn't appear to be available to the general public. I had a look for other apps but wasn't able to find one.

Not sure what you're talking about. I've both in my possession (12.9" as well) and neither the Air 2 NOR the Pro 9.7" are throttling at ALL, on extremely heavy loads (Geekbench isn't used to figure throttling, those are quick hits, fast tests and not telling much at all about extended workloads). AnTuTu is Now available on the App Store as well As GFXBench GL specifically to measure sustained workloads - cross platform, cross API 3d bench measuring graphic performance and sustained endurance and long term (workload) stability, render quality/stability and energy/power consumption.

My Air 2 is an incredible tablet. My 9.7Pro eats it for lunch, sustained, quick bursts, 15 minute renders, or 2 hours 'Real Racing!' - I'm not sure where you've seen these super secret tests but they're 'patently false'. Not even the iPhone 6s/6s+ are throttling with their A9s!

The A9x is an absolute BEAST of a chip without throttling or TDP issues and with four iPad 2s (we use them for our business) and a pair of iPad Pro 9.7s/single iPad Pro 12.9, of all -- using same app whether rendering a flick, batch processing photos, racing cars, or transferring large amounts of data on the radios, the Air 2 consistently is warmer to the touch than the newer Pro of the same size.

Just my 2 cents, but with six of the iPads, four Air 2s, two new Pros, same size, with a seventh thats much larger @ 12.9" (But, clocked higher, more RAM, NO issues!)

These things stay cool as a cucumber in comparison with my iPad 4, original Air 1 and Mini 2s while doing any processor intensive work

The 'A' series chips (check Anand's site as he actually runs a 20-40 minute bone cruncher of a bench) absolutely destroy any other SoC on the market when it comes to NO throttling and consistent - straight line near top frequency (SoC's speed) the entire time graph. The SnapDragons, nor Exynos haven't held a candle to them in years, nor has the 'previous' A series chip

Perhaps you've got an issue with your rig? I'd take it in to have it checked.

This. My pro 9,7 gets definitely much hotter than my air 1. It seems than that I have to let Apple check it

Of the two iPad Pro's (9.7") that I've tested both showed throttling _must_ faster than the iPad Air 2 did. To quote myself from another thread. This is using 3DMark Sling Shot Extreme Benchmark, tests run one after the other on both devices.

(Benchmark, no demo, wifi on, brightness 50%, volume at zero, true tone off, night shift off, auto brightness off)

Pro 9.7           Air 2
3088                  1932
3027                  1917
3050                  1918
2862                  1923
2929                  1929
2768                  1926
2670                  1904
2741                  1875
2621                  1825
2716                  1800
2600                  1793

The first time I ever ran the benchmark the initial demo was on and I got a result of 2392, which was well below the average of 3037. Running the same thing on the Air 2, it got 1915 (just a bit under its average of 2054.)

As to whether the A9 and co chips throttle, well they do. it may not be much but they do, on the page below you will find three figures where they've tested the 6, 6S and 6S+ over different periods and you can clearly see the throttling.

Okay, well I've had some time to test with the GFXBench GL & GFXBench Metal apps you mention, and I'd be _very_ curious to see your results @akdj and other peoples for the Long Time Performance / Battery Lifetime test (Start App -> Test Selection -> deselect all, then select Battery Test - Manhattan 3.1). It would be useful to see whether my Pro 9.7 does have an issue.

The results are quite interesting, particularly as you can see the Air 2 held its results pretty solidly for 20 iterations and only then did the scores drop off, where the Pro 9.7 was dropping off after the first and kept on dropping. (Though still remaining about twice as fast as the Air 2).

Left iPad Pro 9.7, right iPad Air 2 (GFXBench Metal - Battery Test - Manhattan 3.1)



Conversely on T-Rex test, on both the GL and Metal versions of GFXBench the iPad Pro 9.7 doesn't bat an eyelid doesn't appear to throttle where the Air 2 does. The graph for the Pro looks wild, but the scale is tiny (a difference of 1 between 30 iterations of the Metal version of the test, and a difference of 5 for the OpenGL version of the test). Where the Air 2 clearly drops about 300 points after 16-17 iterations.

Left iPad Pro 9.7, right iPad Air 2 (GFXBench Metal - Battery Test - T-Rex)



Left iPad Pro 9.7, right iPad Air 2 (GFXBench GL - Battery Test - T-Rex)



I've run the Manhattan Metal test a couple of times on the Pro and both times with similar results. (frame time results messed up due to massive spike in the max frame time, 3rd attempt ruined as the app crashed)

Left iPad Pro 9.7, right iPad Pro 9.7 roughly 2 hours later, and one hour since device last used.



So overall, its clear on this sample size of two (plus the score results on GFXBench) that both devices do throttle. However how / why is different. I'm curious:

1) Why does the Pro throttle so quickly in the Manhattan battery test (GFXBench Metal) and 3dMark's Sling Shot Extreme
2) Why is the Air 2 so consistent over its initial runs before then dropping.
3) Why doesn't the Pro throttle at all on the T-Rex battery test when the Air 2 seemingly does.

(GFXBench is a little flakey. 3rd test crashed, 4th failed because it decided that the iPad was suddenly plugged in when it wasn't)
