Question: I recently purchased a Raspberry Pi 3, which I understand to have the BCM2837 chip. When I purchased a codec from raspberrypi.com, I was asked to run:

cat /proc/cpuinfo

I was surprised to see the following output at the bottom:

Hardware : BCM2835
Revision : a22082
Serial : 

Why should I see this output from a new Raspberry Pi 3, instead of the BCM2837 chip?

Answer: 
Quoted from a Raspberry Pi engineer :

For info my Pi3 does the same 'cat /proc/cpuinfo' :

Hardware : BCM2835
Revision : a02082
I did some more digging and found [this.](https://github.com/raspberrypi/documentation/blob/master/hardware/raspberrypi/revision-codes/README.md)
Basically, the 'revision code' is the only useful bit of information. Look it up in this table to confirm what you really have. In your case, it's a Pi3B manufactured by Embest.
