Raw images in the SX50 are made of 12-bits per color channel. That means these color channels have 4096 different intensities.

Probably a little less as there are usually special values on the bottom of the scale. But this has small effect. What has large effect on the number of truly different values is noise - DxOMark measures SNR at about 30 dB at the base ISO, meaning there are approximately 1000 truly different values corresponding to about 10 bits, and the other 2 bits contain noise. By ISO 400 or so useful information falls to 8 bits.

As usual, for a camera with small pixels the advantage you can get out of RAW is smaller than what you can get out of certain large-pixel cameras with 14-bit RAW and DR of 14EV.
