The 7800 can't match the 7700 for speed

I have two Billion routers, the 7700N and the 7800. After experimenting with them, I find that the absolute maximum downstream connection speed I can get with the 7700N is 0.5 Mbps higher than with the 7800, at 22.1 Mbps against 21.6 Mbps. In each case I have tweaked the SNR down as far as it will go, and kept all other settings the same between the two. Can anyone suggest a reason for this difference, please? I would have expected it to be the other way round. Many thanks.

What was the SNR reading from both devices??

Thanks for responding.
The default SNR, set by my ISP, is 3dB (I'm on a very good line, 1 km from the exchange). I can tweak the 7700N down to 50% of the default, and the 7800 down to 40%, whilst maintaining a stable connection. If I set them both at 50%, the 7700N outperforms the 7800 by 0.9 Mbps downstream connection speed.
