VSX is a SIMD introduced in POWER7. It's similar to AVX. VSX2 is not actually a formal name. It's just that VSX was improved in POWER8 and later in POWER9. Thus, this follows Gentoo's naming in naming them informally VSX and VSX3 to differentiate the improved VSX in newer CPU's.

Also, powerpc64le has a different default from powerpc64, because powerpc64le's baseline is POWER8 (which already has VSX with improvements), while powerpc64's baseline is G5, which is much older and actually precedes VSX.
