CMPPS - CoMPare Packed Single

CMPPS xmm1, xmm2/m128, imm8    (S1
__m128 _mm_cmp_ps(__m128 a, __m128 b, int imm8)

For each float, if the condition specified in imm8 is met, store 1, else store 0, in all bits of the corresponding float of (3).
VCMPPS xmm1, xmm2, xmm3/m128, imm8    (V1
__m128 _mm_cmp _ps(__m128 a, __m128 b, int imm8)

For each float, if the condition specified in imm8 is met, store 1, else store 0, in all bits of the corresponding float of (3).
VCMPPS ymm1, ymm2, ymm3/m256, imm8    (V1
__m256 _mm256_cmp_ps(__m256 a, __m256 b, int imm8)

For each float, if the condition specified in imm8 is met, store 1, else store 0, in all bits of the corresponding float of (3).
VCMPPS k1{k2}, xmm2, xmm3/m128/m32bcst, imm8    (V5+VL
__mmask8 _mm_cmp_ps_mask(__m128 a, __m128 b, int imm8)
__mmask8 _mm_mask_cmp_ps_mask(__mmask8 k2, __m128 a, __m128 b, int imm8)

For each float, if the condition specified in imm8 is met, store 1, else store 0, in 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.
VCMPPS k1{k2}, ymm2, ymm3/m256/m32bcst, imm8    (V5+VL
__mmask8 _mm256_cmp_ps_mask(__m256 a, __m256 b, int imm8)
__mmask8 _mm256_mask_cmp_ps_mask(__mmask8 k2, __m256 a, __m256 b, int imm8)

For each float, if the condition specified in imm8 is met, store 1, else store 0, in 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.
VCMPPS k1{k2}, zmm2, zmm3/m512/m32bcst{sae}, imm8    (V5
__mmask16 _mm512_cmp_ps_mask(__m512 a, __m512 b, int imm8)
__mmask16 _mm512_mask_cmp_ps_mask(__mmask16 k2, __m512 a, __m512 b, int imm8)
__mmask16 _mm512_cmp_round_ps_mask(__m512 a, __m512 b, int imm8, int sae)
__mmask16 _mm512_mask_cmp_round_ps_mask(__mmask16 k2, __m512 a, __m512 b, int imm8, int sae)

For each float, if the condition specified in imm8 is met, store 1, else store 0, in 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.
