--- Comment #1 from Robin Dapp <rdapp at gcc dot gnu.org> ---
x86 (-march=3Dnative -O3 on an i7 12th gen) looks pretty similar:

.L3:
        movq    (%rdi), %rax
        vmovups (%rax), %xmm1
        vdivps  %xmm0, %xmm1, %xmm1
        vmovups %xmm1, (%rax)
        addq    $16, %rax
        movq    %rax, (%rdi)
        addq    $8, %rdi
        cmpq    %rdi, %rdx
        jne     .L3

So probably not target specific.  Costing?=
