This Is How Much Hotter The Raspberry Pi 3 Gets Than The Raspberry Pi 2

Written by Michael Larabel in Raspberry Pi on 7 March 2016 at 06:44 AM EST. 10 Comments
As part of the numerous Raspberry Pi 3 benchmarks published this weekend, I had an article devoted to how the Raspberry Pi 3 gets rather warm under load. For those interested, here are some follow-up tests showing just how warm the RPi3 gets in comparison to the Raspberry Pi 2.

The result here is an extension of yesterday's Raspberry Pi 3 thermal SoC testing with adding the Raspberry Pi 2 results with monitoring its SoC temperature via the Phoronix Test Suite while running the same exact benchmarks in the same manner, etc. For those running PTS on your Pi, it's as easy to record as setting the MONITOR=sys.temp environment variable.

Putting the Raspberry Pi 2 at a slight disadvantage is that it was running within a case, but that didn't even matter for the profound difference compared to the ARM 64-bit Raspberry Pi 3:
Raspberry Pi 2 vs. Raspberry Pi 3 Thermal

The Raspberry Pi 3's average SoC temperature unader load was 61C with a peak of 82C. Meanwhile, the Raspberry Pi 2 had an average temperature of 48.9C and a peak of 59.C. The Raspberry Pi 3 under load was peaking at more than 20 degrees higher (C) than its predecessor. This was even with the Raspberry Pi 2 running within a case while the RPi3 was completely open air.
Raspberry Pi 2 vs. Raspberry Pi 3 Thermal

It was all the same testing, the line on the RPi2 is drawn out just because that testing took a lot longer than the Raspberry Pi 3. You can dig through all of these Raspberry Pi 2 vs. Raspberry Pi 3 thermal points via this result file.

There's nothing stopping you from adding your own heatsink to the Raspberry Pi 3 if you will be routinely stressing the $35 ARM board. Our friends at CompuLab were even experimenting with a potential Pi heat-plate design.
