is libx264/265 and X264/265 same?

Hi

I believe libx264 is used in FFMPEG and X264 in GUI like handbrake and staxrip(if chosen)

Is libx264 and X264 essentially the same?
using same parameters they should produce equivalent/identical quality?
is there any difference in speeds between the two( at same encoding parameters)
Thanks

Essentially the same - they are based same library

Same output if same settings (assuming other processing was the same, and same core/version)

Some options like qpfile are not available in libx264/libx265 , only in cli version

No material speed difference if everything else is the same

x264 is like a front-end to libx264. It's there to configure the lib
