But is there any value to coverting to bytes (B) from bits (b) in this particular case?

Well, if you're looking to see if the video card has enough memory to fit those two frame buffers in memory, and given that video card memory is given in bytes, then you either need to convert the memory required to bytes or the memory available to bits.

And, unless I'm mistaken, none of a video card's memory is dedicated to either the frame buffer or textures, et al.
