The question actually is, is a PYD file created from C faster then a
PYD file from Pyrex ?
Most likely, yes.
However, when comparing to Cython instead of Pyrex, the answer really
depends on your code. Cython cannot be faster than the equivalent C code,
simply because

How do you plan to create an extension module (*.so, *.pyd on Windows) from
Python source then?

What do you mean? An African or European swallow?
Of course it depends on your choice of algorithm, programmer ability.familarity

For this code, the manually-written version will most likely
be faster than the Pyrex-generated one.
This is, most likely, because the manually-written version will
assume a specific data type for the arguments (e.g. int), which
Pyrex will

Since a .pyd file from Pyrex is also from C, the question is ill-posed.
It is equivalent to "Does the C code generated by Pyrex compile to
faster or slower machine code than the C code generated
Sorry that was a typo...

I know it will depend on how it is written, but let's imagine a tiny
example, like

result = arg1 + arg2
return result
