Snapdragon 620 takes on the Snapdragon 615 in Qualcomm's latest heat test

It was just Saturday night when we passed along a test conduced by Qualcomm that showed how the unreleased Snapdragon 815 runs cooler than the feverish Snapdragon 810 and the Snapdragon 801. Now, Qualcomm has apparently heat-tested the unreleased Snapdragon 620 and the currently available Snapdragon 615.

Unlike the previous tests, which used the game Asphalt 8 to stress the chips, Qualcomm turned to Mortal Combat 5. That is a surprising choice since it is more demanding and the chips being tested are Qualcomm's mid-range chipsets. Perhaps Qualcomm should have used Mortal Combat 5 for the tests involving its flagship chips.

Nonetheless, the game was played on a device with a 4.7-inch IPS display with a 720 x 1280 resolution, packing 1.5GB of RAM and no cellular antenna or radio. Each chipset played Mortal Combat 5 for 20 minutes before the thermometer was employed. The results? The Snapdragon 620 hit 107.6 fahrenheit, cooler than the 114.8 degrees reached by the Snapdragon 615. On a device with a cellular antenna and radio, the temps will be a bit higher.

According to the tests, the Snapdragon 620 cools down constantly when game time is over. The Snapdragon 615 got cooler for the first 15 minutes of rest before the temperature started acting a bit strange. The behavior of the latter chip was apparently something that Qualcomm was able to fix with its next-gen mid-range chipset.

wdf are these chipsets even released yet and you guys still make a thread about it w/e im happy

True, the 815 isn't even announced yet Like I said for the 815 These tests are pointless without more detail We need FPS counter, CPU clocks, GPU clocks, load percentage 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

well Qualcomm only relied on higher clocked processor clocking up 2.7 Ghz, and they were the dominant chip maker at that time but they didn't focus on 64 bit which was a let down, and 801, 805 are just a minor upgrade from 800 but the thing turned ugly when apple introduced 64 bit arm processor for mobile and soon all followed the same path, earlier qualcomm used to be on the cutting edge but now they are using arm's designed processor so what's the point in using it when samsung can produce the same along with 14 nm processor, Although they have good GPU but i think that ARM's Mail can do better, but apple with A8 blows each and every chip out, with dual core 1.4 Ghz processor they can beat almost every android chip on gaming, opening apps. Even with low clocked processor apple can beat 2.3 Ghz octacore processor of samsung and qualcomm....and pls qualcomm make those heat sink a bit further...

you're wrong. per core of a8 is bigger than per core of other (that's mean apple can add 2 core to cpu because have bigsize/core. Benchmark single core a8 is winner but multi core a8 is loser.

SD805 was quite an upgrade over the 800.

And again, 8 cores. Just quantities, not qualities. I think, if Qualcomm can make a good chips just with dual cores or max 4 cores, heat issues should be decreased. Example : For mid range = 1,2 Ghz dual cores cortex A7 + 1,7 Ghz dual cores krait. That should be enough if optimization had been done

It wouldn't be enough, Krait cores are pretty old now, they wouldn't be as good as the new A57 or A72 chips. And two of them is just not enough these days. Yes, it has 8 cores but don't forget about big.LITTLE architecture - they hardly ever work together (Qualcomm is not Mediatek).

ya man optimization......sure its good.

I don't think these tests are doing qualcomm any good. Am not seeing the sense in them

So qualcomm is saying that don't buy current chips, upcoming chips are better.

Details about SD620 are out: It uses four new Cortex A72 chips (clocked at 1,8 GHz) as faster cores (and 4xA53) so it should be pretty quick.
