Long story short, there are two differences:
The color is changed from the default color to explicit black;
The paper size is changed from the default of your TeX distribution setup to letter paper.
One thing that changes is the PDF metadata which contains the date in which it was generated and an unique ID generated with that info. You can suppress those to create the exact same PDF using (reference):
pdfinfoomitdate=1
pdfsuppressptexinfo=-1
pdftrailerid
(assuming you are using pdfTeX).
That said, you can disable the compression to make the PDF human-readable (or as close as it can get):
pdfcompresslevel=0
pdfobjcompresslevel=0
and then run pdflatex on two files and diff them:
$ diff -a notikz.pdf tikz.pdf

It seems to be a lot, but actually there are only few relevant changes. Most of the above are address changes to PDF objects, for example the first difference:
3c3
< 3 0 obj
---
> 6 0 obj
Says that the difference is an object which was numbered 3 and now is numberered 6. Later on references to this object will change as well (edited):
17,20c23,26
< /Contents 3 0 R
---
> /Contents 6 0 R
Also, at the end, the addresses (offset in bytes) of the objects in the file are changed because the file has changed.
The only relevant changes are three:

The first one is the actual text you printed. The stream without tikz was:
stream
BT
/F8 9.9626 Tf 148.712 707.125 Td [(This)-333(is)-334(a)-333(test.)]TJ 154.421 -567.87 Td [(1)]TJ
ET
endstream
and with tikz it became:
stream
0 g 0 G
0 g 0 G
0 g 0 G
BT
/F8 9.9626 Tf 148.712 657.235 Td [(This)-333(is)-334(a)-333(test.)]TJ
0 g 0 G
154.421 -567.87 Td [(1)]TJ
0 g 0 G
ET
endstream
The 0 g 0 G are color specification which are inserted in the PDF. These changes are actually inserted by the color driver and you can see them if you usepackagecolor. They are explicitly saying that the text is black, and not the default color (which is also black :).
The third difference is also related to the color driver which adds color information to the loaded fonts:
/ColorSpace 3 0 R /Pattern 2 0 R /ExtGState 1 0 R
(remember object number 3 which changed to 6? This statement points to the new object number 3).
Finally, the second part is related to the graphics driver:
17,20c23,26
< /Contents 3 0 R
< /Resources 1 0 R
< /MediaBox [0 0 595.276 841.89]
< /Parent 5 0 R
---
> /Contents 6 0 R
> /Resources 4 0 R
> /MediaBox [0 0 612 792]
> /Parent 8 0 R
which, apart from object references, changed the value of /MediaBox, which is basically the paper size. When you usepackagegraphics the paper size is changed from the default (which depends on how your TeX distribution is set up) to letter paper.

The 0 g 0 G are color specification which are inserted in the PDF. These changes are actually inserted by the color driver and you can see them if you usepackagecolor. They are explicitly saying that the text is black, and not the default color (which is also black :).
The third difference is also related to the color driver which adds color information to the loaded fonts:
/ColorSpace 3 0 R /Pattern 2 0 R /ExtGState 1 0 R
(remember object number 3 which changed to 6? This statement points to the new object number 3).
Finally, the second part is related to the graphics driver:
17,20c23,26

< /Resources 1 0 R
< /MediaBox [0 0 595.276 841.89]

which, apart from object references, changed the value of /MediaBox, which is basically the paper size. When you usepackagegraphics the paper size is changed from the default (which depends on how your TeX distribution is set up) to letter paper.

Long story short, there are two differences:
The color is changed from the default color to explicit black;
The paper size is changed from the default of your TeX distribution setup to letter paper.
One thing that changes is the PDF metadata which contains the date in which it was generated and an unique ID generated with that info. You can suppress those to create the exact same PDF using (reference):
pdfinfoomitdate=1
pdfsuppressptexinfo=-1
pdftrailerid
(assuming you are using pdfTeX).
That said, you can disable the compression to make the PDF human-readable (or as close as it can get):
pdfcompresslevel=0
pdfobjcompresslevel=0
and then run pdflatex on two files and diff them:

It seems to be a lot, but actually there are only few relevant changes. Most of the above are address changes to PDF objects, for example the first difference:
3c3
< 3 0 obj
---
> 6 0 obj
Says that the difference is an object which was numbered 3 and now is numberered 6. Later on references to this object will change as well (edited):
17,20c23,26
< /Contents 3 0 R
---
> /Contents 6 0 R
Also, at the end, the addresses (offset in bytes) of the objects in the file are changed because the file has changed.

It seems to be a lot, but actually there are only few relevant changes. Most of the above are address changes to PDF objects, for example the first difference:
3c3
< 3 0 obj
---
> 6 0 obj
Says that the difference is an object which was numbered 3 and now is numberered 6. Later on references to this object will change as well (edited):
17,20c23,26
< /Contents 3 0 R
---
> /Contents 6 0 R
Also, at the end, the addresses (offset in bytes) of the objects in the file are changed because the file has changed.
The only relevant changes are three:
7a8,10
> 0 g 0 G
> 0 g 0 G
> 0 g 0 G

The first one is the actual text you printed. The stream without tikz was:
stream
BT
/F8 9.9626 Tf 148.712 707.125 Td [(This)-333(is)-334(a)-333(test.)]TJ 154.421 -567.87 Td [(1)]TJ
ET
endstream
and with tikz it became:
stream
0 g 0 G
0 g 0 G
0 g 0 G
BT
/F8 9.9626 Tf 148.712 657.235 Td [(This)-333(is)-334(a)-333(test.)]TJ
0 g 0 G
154.421 -567.87 Td [(1)]TJ
0 g 0 G
ET
endstream
The 0 g 0 G are color specification which are inserted in the PDF. These changes are actually inserted by the color driver and you can see them if you usepackagecolor. They are explicitly saying that the text is black, and not the default color (which is also black :).
The third difference is also related to the color driver which adds color information to the loaded fonts:
/ColorSpace 3 0 R /Pattern 2 0 R /ExtGState 1 0 R
(remember object number 3 which changed to 6? This statement points to the new object number 3).
Finally, the second part is related to the graphics driver:
17,20c23,26
< /Contents 3 0 R
< /Resources 1 0 R
< /MediaBox [0 0 595.276 841.89]
< /Parent 5 0 R
---
> /Contents 6 0 R
> /Resources 4 0 R
> /MediaBox [0 0 612 792]
> /Parent 8 0 R
which, apart from object references, changed the value of /MediaBox, which is basically the paper size. When you usepackagegraphics the paper size is changed from the default (which depends on how your TeX distribution is set up) to letter paper.

Yes, pgf will load the graphics-drivers and this will set/change the pdf page size to letter.

@subhamsoni Denis I do not care so much for changes in the date of creation of the file and things like that, but the changes here go beyond that, as explained by Phelype Oleinik down below.
