The page you were looking at is "marketing nonsense" only. This includes CPU brand names (Xeon, Celeron, Core i7, etc) and CPU model names ("X3470"). Please note that there's also "marketing nonsense" (things intended for salespeople that are completely useless for software developers). I don't know if there's a less insane way of deciphering it. You can find the ranges of model numbers by painstakingly trawling through all of the various specification updates while muttering obscenities under your breath (note: this is the traditional method). CPUID.family = 6 means it's anything from Pentium Pro (1995) to the latest Haswell (2014) except "Netburst"įor CPUID.family = 6 you have to check the CPUID.model field.CPUID.family = 15 means it's a "Netburst" (Pentium 4, Pentium D, Pentium EE, and some Celerons and not others, and some Xeons and not others).The package gathers all information during package initialization phase so its public interface will not need to execute the CPUID instruction at runtime. The cpuid package provides convenient and fast access to information from the x86 CPUID instruction. CPUID.family = 4 means it's an 80486 (no performance monitoring) Intel CPUID library for Go Programming Language.CPUID not supported means it's 80486 or older (there are ways to tell which, but you won't care as there's no performance monitoring).In general for Intel 80x86 and only Intel 80x86 (excluding things like Itanium and Xeon Phi/KNC, and all other 80x86 CPU manufacturers - don't forget to check the "vendor ID" string in CPUID): For "X3470" specifically, it is based on the Nehalem micro-architecture.
