There is 4x the amount of light from F/1.4 to F/2.8.
Each pixel of the D700 covers 4.67x more area.
Not taking QE into consideration that means that every pixel on the D700 would be receiving 18.67x more light!! I have taken a wild stab in the dark but with an ~10 year increase in technology the QE may be light 0.4 vs 0.6 or a 50% increase. This brings the overall system closer to 12.4x increase in detected light per pixel.
