DxOMark published their test results for the Nikon D3300 camera:
“Signal quality of the Nikon D3300 sensor compares well against other APS-C models in the line-up and it outshines that of rival entry-level models. Although the results are similar to its predecessor, the removal of the AA filter promises improved sensor resolution. Combine that with the revised features and capability and the new Nikon D3300 looks better value than ever.”
