It's difficult to find direct evidence of this on the internet, except 
in examining video card models over time. A video card is a combination 
of firmware and hardware. So with newer chips, they load a different 
firmware onto it and put different sets of ram on the board. Now you've 
got a newer process (like manufacturing process) chip that is running an 
older graphics card setup. A newer chip which is cheap, or perhaps a 
flawed version of an awesome chip (they can disable sections of the 
silicon), running slower and such, generates less heat, and performs to 
the older video card spec.

I couldn't find anything that details this specifically, but it's how 
CPUS are handled and priced.
