Isn't it SVE? So far, it has been only implemented AFAIK by the A64FX, which is used by the current #1 supercomputer in the TOP500 list, but it wouldn't surprise me if we start seeing it on newer 64-bit ARM chips.

SVE2 is guaranteed in ARMv9.

Neoverse V1 has SVE (with 2x256b units) and Neoverse N2 has SVE2 (w/ 2x128b units).

Note that SVE is a superset of Neon and SVE2 is a superset of SVE.
