Not that a difference in file size would mean anything. In theory, the bits could be distributed completely different and still the exactly same file size could be hit!
Instead, you should decompress both files to uncompressed Wave/PCM and then add the
inverse of the one file to the other file (e.g. use "mix paste" in Audition).
As long as the result is silent - or at least
very close to silent - there is no reason to be concerned. Furthermore, you could also try to ABX the files...
[EDIT]
I just converted a
complete album (Chinese Democracy) to Opus format, once using the "i386" build and once using the "sse2" build. Both files came out at identical size.
Files were
not identical by content. Of course, not. The encoder signature string already differs.
Next I decoded the "i386"-encoded file with the "sse2" decoder and the "sse2"-encoded file with the "i386" decoder, which should be the most extreme test case, I think.
The difference between the two decoded files
is silent. There are a few minor peaks in a few places, but noting critical. Average RMS of the diff is -85.79 dB.
