Qualcomm Snapdragon 815 runs cooler than the Snapdragon 810 and Snapdragon 801
posted by Alan F. / Mar 22, 2015, 1:17 AM
But worries about the chip started all over again when the HTC One M9 was found to be running a benchmark test at a rather unseasonably warm 132 degrees fahrenheit. All of the other handsets in the test ran cooler including the HTC One (M8) and Samsung Galaxy Note 4. Those models hit 102 degrees and 100 degrees, respectively. The HTC One M9 was the only phone in the test that had the Snapdragon 810 SoC inside. (HTC has since sent out a software update that lowered the temperature on the unit to 104 degrees fahrenheit).
Now, a new test has been run internally by Qualcomm using the Snapdragon 815, Snapdragon 810 and the Snapdragon 801. The chips were placed in three separate devices with no cellular radio, a 5-inch screen with resolution of 1080 x 1920, and 3GB of RAM. Note that the absence of antennas and radios means that in real world application, all three chips will run a little warmer than seen in the test. We should point out that the Snapdragon 815 has not yet been released.
The same graphics intensive Asphalt 8 game was played, but unlike the previous test which used a medium graphics setting, this time the testers turned the dial to high graphics. As it turns out, the Snapdragon 815 ran the coolest at 100.4 degrees fahrenheit. Next came the 107.6 degrees hit by the Snapdragon 801. Running the hottest was the Snapdragon 810 at 111.2 degrees.
The bottom line is that phones using the Snapdragon 815 should not have to face the same worries by consumers about overheating. Too much heat can lead to shorter battery life and shorter device life as well. And of course, no one wants to feel like that are holding a Hot Pocket that just came out of the microwave every time they want to use their phone. There is no word when the Snapdragon 815 will start to be found inside handsets.
Thanks for the tip!
At same load, a more efficient processor will be definitely cooler. It's like running 801 at full load while 815 must be running at like 50% duty cycle, so it's not the top temperature for 815. A more interesting comparison would be comparing them both at top load i.e. much higher for 815 compared to 801 as it's a most potent chip.

This is true. Why did they play a game? I think a chart at load would have been more helpful. Put the temperatures for each SOC at a specific load percentage. At 100% load, 801 is xx degrees, 810 is xx degrees, 815 is xx degrees.

It was tested with Asphalt 8 Airborne They should have included more detail At least FPS counter, CPU clocks, GPU clocks e.g. I could cheat this test by limiting my Nexus 5 to 30C My Nexus 5 would destroy them based on temps But my Nexus 5 would get destoryed in terms of much lower framerate and CPU/GPU clocks

Yeah. I've read that Qualcomm tested all the chips in Asphalt 8. Don't know if Adreno struggles there but Mali T760MP6 inside my Note 4 is reaching 60 fps EASILY running about 60% of its top performance. Off cource the device doesn't get even warm. So the test is made to mislead people.

i'm afraid that's not the case at all tyrion. if you wanted to run them both 'as fast as they can go', then the limiting factor would be heat, and they'd both run at exactly the same temperatures and the experiment would be pointless. you either limit by the task and test for heat, or limit by heat and test for performance on the task. here they're using the former.

If a device gets above 120~(depends on the device) it can go into meltdown mode. Like, even lowering the CPU load doesn't cool it down because the CPU is hot which make the battery hot which releases it's charge more quickly which produces more heat and so on... Definitely ruins the long term life of a battery as well as possible battery leakage or even explosion in severe cases. I've fallen asleep with my phone on the charger which ended up under my pillow and it got burning hot. Not safe.

OK so I need to use Google to convert Fahrenheit to Celsius because everyone know how much is 130 F..FYI only couple of countries using Fahrenheit,rest of the world using Celsius.

because qualcomm use Fahrenheit on their tes sot PA should write it as it is. Why not convert it yourself, google like you said simple! and stop being offended over something silly like this.

This isn't silly nor is it an answer towards an offence. For something like this PA should know that most readers here are using Celsius, so it is not suggested for PA to only show Fahrenheit. Whats wrong with a mere suggestion?

"european" problems, i guess americans are that smart being able to convert, and if not, know how to use a PC and 'whine' about it.

Graphs are dodgy. Lets see the temp graphs at peak CPU performance not throttled.. Then compare that to the Exynos 7420..

I've lost my faith in Qualcomm and I'm mad at them because now HTC M9 is a no go for me and Galaxy S6 has no competition this year.

Dont be sure yet .. Lets wait for z4 and g4 :)

I don't like to rumour-bash any device but these graphs are really bad. All graphs don't have flat stable part, temperatures were rising during the test (which is normal of course) and then test or graphs were cut at some arbitrary point. Maybe temperature was still raising after test|graph end, or maybe not - nobody can tell this looking at these graphs. Really bad news preparation at Qualcomm.

And M9 is a huge disappointment for what being hot which there is no true proof for it yet. Not using useless1440p. And what??? you lighten me.
