The area of a 1" sensor is just a little more than 1/3 the area of an APS-C: 116 sq mm. With 20 million pixels, that means the RX10 Mk4 has approx. 172,400 pixels per square mm.
In other words, the RX10 Mk4 has a far more densely crowded sensor than your 70D. Nearly 3X as many pixels per square mm, in fact. To accomplish that, the pixel sites must be smaller and have less space between them. This can't help but reduce image quality noticeably....
Just to give an example of what the two gentlemen above are talking about...
First photo: original taken hand-held at 600 mm and ISO 640.
Second Photo: A 10x8 crop out of the first photo.
Third Photo: A 10x8 crop out of the second photo.
Some PP was required.
