Bandwidth = Width * Height * bpp * FPS /8Width: Resolution widthHeight: Resolution heightbpp: Bits Per Pixel (colour depth)FPS: Frames Per Second/8: 8 bits to a ByteFor Example, A Web Browser source, running at 4K 30FPS has the following specifications:Width=3840, Height=2160, Web Browser bpp=32, FPS=30, /8: 8 bits to a Byte.Its Bandwith = 3840 * 2160 * 32 * 30 / 8 = 995328000 i.e., about 1GB/s.
