    The Intel Intrinsics Guide is an interactive reference tool for Intel intrinsic instructions, which are C style functions that provide access to many Intel instructions - including IntelВ® SSE, AVX, AVX-512, and more - without the need to write assembly code. Also, code that is written in a high-level language can be compiled into assembly and "hand optimized" to squeeze every last bit of speed out of it. As hardware manufacturers such as Intel and AMD add new features and new instructions to their processors, often times the only way to access those features is to use assembly routines. That is, at
