The DxO Mark Score of Canon 1DX is not confirmed yet but take a look at Canon 1Dx vs 5D Mark III High ISO images comparison, the Canon 1Dx images showing better color and more details at High ISO compared to 5D Mark III.
If the lighting conditions you’re shooting in doesn’t require an ISO over 3200, both cameras will deliver almost identical quality images. However, if you need to shoot with an ISO 6400 and above (especially at 12,800 and above), the Canon EOS-1D X will deliver a superior, cleaner image. This does not mean the Canon EOS 5D Mark III cannot render deliverable images at ISO 12,800, it just means that the Canon EOS-1D X controls the noise in the shadow area much better in a high ISO. See it for yourself in the images below.
