At the moment, for the term 'processor architecture' is not a narrow interpretation. According to the programmers at the processor architecture is understood as its ability to perform the specified selection of computer codes. Almost any modern desktop computers from the family x86, or Intel-compatible processor architectures IA32 (32-bit processors Intel). Its start has been made has been i80386 processor from Intel, however, in the next generations of processors was extended and complemented by both the Intel (introduced a new set of commands sse, SSE2, SSE3, and MMX), and third-party developers (teams 3DNow! and Extended 3DNow!, emmx from corporations AMD). However, the creators of the computer contains the phrase 'processor architecture' (Sometimes to not get confused, use the term 'micro-architecture') is slightly different meaning. How they think, processor architecture reflects the beginning of the internal organization of some families of processors. For example, architecture of Intel Pentium denoted as P5, the Pentium ii and Pentium iii – P6, and a recently popular Pentium 4 refers to the architecture NetBurst. After the closure of Intel's architecture for the P5-party, amd was forced to create their own own architecture – K7 processors Athlon and Athlon xp, as well as the K8 for Athlon 64 processors..
