The ardunio is a completely different product from the Pi,  About the=20

The did consider a microcontroller based option but decided that for=20
thier target
application a "mobile phone SOC" would be a better fit than a=20
microcontroller.
Unfortunately none of the mobile phone SOCs are very open. Some
manufacturers release arm side documentation more freely than others but
afaict none of them release details of the GPU.

Afaict a broadcom part was chosen because they had people on the
inside who could negotiate a good deal for relatively small volumes.
