I686 is only the Instruction Level of the cpu, including 32bit and 64bit, i68632bit

(Transfer) i686 is only the cpu instruction level, including 32bit and 64bit, i68632bit

I stands for intel series cpu386, which is applicable to almost all x86 platforms. It can work normally, whether it is the old pentum or the new pentum-IV and K7 series CPUs! That I refers to Intel-compatible CPU. As for 386, It is the CPU level! I586 is a computer of the 586 level. What is it? This level includes the first generation of pentum mmx cpu, AMD's K5, K6 series CPU (socket 7 plug-in), and so on. i686 Intel series CPU after pentun II, and CPU levels after K7 belong to this 686 level! Noarch is not limited by any hardware level. 1. i386 is applicable to all 32-bit CPUs of intel and AMD. and 32 CPUs in X86 architecture. intel Platform includes 8086,80286, 80386,80133, Pentium series (1.2.3.4), sai Yang series, Pentium D series and centrino P-M, core duo and so on. 2. x86_64 is applicable to intel's Core 2 Duo, Centrino Core 2 Duo, and Xeon and AMD Athlon64/x2, Sempron64/x2, Duron64, etc. 64-bit cpu.3.I686 with X86 architecture is only a subset of i386, the supported cpu starts from Pentium 2 (686) and is not supported by the previous model.
