Is there a overheating protection circuit integrated into the Raspberry Pi like in desktop processors from Intel or AMD? When I did research about this question I just found vendor specification about operating temperatures ranges. How does a Raspberry Pi deal with high temperature?

I've tried it out. I measured the external temperature and monitored also the temperature provided by the sensor in the AP. I run a benchmark with the same result on room temperature and when I heated the PI up with hot air to 70°.

Yes, as the temperature rises the CPU frequency is lowered to prevent damage. The throttling begins around 82 degree Celsius. You can check the CPU Frequency with the following command:

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

or using the GUI widget.

The following links provide additional info and benchmarks:
