Can AVX instruction be executed in parallel

Hi,

Can two avx instrcutions can be executed in parallel?

For example,

Version1:

            a1= _mm256_load_ps((Rin +offset)); 
            a2= _mm256_load_ps((Gin +offset));  
            a3= _mm256_load_ps((Bin +offset));

            ac0 = _mm256_mul_ps(a1, in2outAvx_11); 
            ac1 = _mm256_mul_ps(a2, in2outAvx_12);
            ac2 = _mm256_mul_ps(a3, in2outAvx_13);
            
            z0 = _mm256_add_ps(ac0,ac1);
            z1 = _mm256_add_ps(z0, ac2);
            

If I changed this code to 

Version 2:

            a1= _mm256_load_ps((Rin +offset)); 
            a2= _mm256_load_ps((Gin +offset));  
            a3= _mm256_load_ps((Bin +offset));

            ac0 = _mm256_mul_ps(a1, in2outAvx_11); 
            ac1 = _mm256_mul_ps(a2, in2outAvx_12);

/*first two instructions below,  are data independent and might run in parallel */

            z0 = _mm256_add_ps(ac0,ac1);
            ac2 = _mm256_mul_ps(a3, in2outAvx_13);

            z1 = _mm256_add_ps(z0, ac2);

Will version2 code run faster as add and mul intrinsics can execute together?

Or version1 and version two take same time if the compiler rearranges the instructions by itself?
