Bits Per Channel (BPC) is a term for how many colors are available per color channel in a texture (red, green, blue).
8 BPC is 24-bit color, 16 million colors. This is the most commonly used bit depth for game textures.
16 BPC is 48-bit color, 281 trillion colors. This is commonly used for baking Normal maps, as it nearly eliminates banding when you edit them.
32 BPC is 96-bit color. This is often used for HDR images.
