Hi,
I am testing my raspberry pi 3 for its peak performance and maximum temperature,
as mentioned above, i am running both GeeXLab & Sysbench at the same time.
i am getting 166 fps at max, while the sysbench test taking about 3000 secs, the major thing is i am getting the case (surface) temperature to be 44°c (measured with thermo-couple) while the junction temperature read by command is maximum of 68°c.

when compared with the temperatures you are getting it is quite half of it. what is the mistake i might be doing? And did you adjust your IR camera for its emiseivity of processor ?

Pls do reply.

Thanks.

In reply to hlide. yes, Raspbian Jessie is a 32-bit OS.

I guess the OS in Pi 3 was only a 32-bit version, right?

Indeed previous graphs were marketing-like graphs 😉 I updated them!

Saw the GeeXLab plot and thought: Wow! Nearly three times as fast! until I saw the X-axis…
Come on, making readable plots isn’t that hard! It is intended to give a visual impression of the difference but letting it start at an arbitrary place on the X-axis kill this.

Same with the thermal images, the Pi 3 image looks like the Pi 2 – but the scaling is different…

You can do better if you try!

2) Graph not starting from 0! The difference is minimal!
Leave the compatibility and update all the SoC.

Rpi3 is too hot, for same price I prefer Odroid C2
