Compared to the D300S which has the same sensor as the D90, the 7100 looks better at a pixel level, and it would look even better when downsized to the same 12.3mp size as the D90/D300S. It's not 2 stops better in that comparison, but it is better than a D90.

dxomark shows the D5200 and D300s as identical in SNR at the pixel level, and the D90 as better.

Less than 1 dB difference isn't really perceivable in real world use. It takes 3dB to double the noise level. For all practical purposes, they are all nearly identical at a pixel level and the 24mp cams are better when downsized to the same size.
