PCMPEQW - Packed CoMPare EQual Word

PCMPEQW xmm1, xmm2/m128    (S2
__m128i _mm_cmpeq_epi16(__m128i a, __m128i b)

For each WORD, if (1) == (2) set 1, else set 0, to all bits in the corresponding WORD of (3).
VPCMPEQW xmm1, xmm2, xmm3/m128    (V1
__m128i _mm_cmpeq_epi16(__m128i a, __m128i b)

For each WORD, if (1) == (2) set 1, else set 0, to all bits in the corresponding WORD of (3).
VPCMPEQW ymm1, ymm2, ymm3/m256    (V2
__m256i _mm256_cmpeq_epi16(__m256i a, __m256i b)

For each WORD, if (1) == (2) set 1, else set 0, to all bits in the corresponding WORD of (3).
VPCMPEQW k1{k2}, xmm2, xmm3/m128    (V5+BW+VL
__mmask8 _mm_cmpeq_epi16_mask(__m128i a, __m128i b)
__mmask8 _mm_mask_cmpeq_epi16_mask(__mmask8 k2, __m128i a, __m128i b)

For each WORD, 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.
VPCMPEQW k1{k2}, ymm2, ymm3/m256    (V5+BW+VL
__mmask16 _mm256_cmpeq_epi16_mask(__m256i a, __m256i b)
__mmask16 _mm256_mask_cmpeq_epi16_mask(__mmask16 k2, __m256i a, __m256i b)

For each WORD, 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.
VPCMPEQW k1{k2}, zmm2, zmm3/m512    (V5+BW
__mmask32 _mm512_cmpeq_epi16_mask(__m512i a, __m512i b)
__mmask32 _mm512_mask_cmpeq_epi16_mask(__mmask32 k2, __m512i a, __m512i b)

For each WORD, 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.
