The Intel version was compiled for the x86_64 CPU using the Intel classic Fortran compiler. The GNU version was compliled for the x86_64 CPU using gfortran. The Intel version is faster than the GNU version (though not as fast as a native compile to the target CPU that you wish to run it on due to vectorization optimizations that Swiftest takes advantage of), however it is much larger: The Intel version is ~2.7GB while the GNU version is ~300MB. The Singularity container pulls from the same DockerHub container.
