VPCMPUQ - Packed CoMPare Unsigned Qword (imm8=4)

VPCMPUQ k1{k2}, xmm2, xmm3/m128/m64bcst, 4    (V5+VL
__mmask8 _mm_cmpneq_epu64_mask(__m128i a, __m128i b)
__mmask8 _mm_mask_cmpneq_epu64_mask(__mmask8 k2, __m128i a, __m128i b)

For each unsigned QWORD, if (1) != (2) set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the comparison is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.
