1. Overview The string ACPI GenuineIntel---Intel64-family-6-model-140 appears in system logs, CPU identification routines, or ACPI (Advanced Configuration and Power Interface) tables on x86_64 systems. It is not a random string but a structured identifier providing specific details about the CPU architecture, vendor, family, and model stepping as recognized by the ACPI firmware. 2. Breakdown of Components | Component | Value | Meaning | |-----------|-------|---------| | ACPI | N/A | Indicates the identifier originates from ACPI namespace or tables (_PDC, _OSC, or processor objects). | | Vendor | GenuineIntel | Confirms the CPU is manufactured by Intel. | | Architecture | Intel64 | Supports Intel 64-bit architecture (AMD64 compatible). | | Family | 6 | Hex 0x06 – signifies the core microarchitecture family (not the legacy 86 family). Modern Intel CPUs use family 6. | | Model | 140 | Hex 0x8C – specific model number within family 6. | 3. CPU Identification: Family 6, Model 140 3.1. Determining the Processor Generation Intel family 6 covers all modern Core, Xeon, Atom, and Pentium/Celeron designs from Pentium Pro (1995) to present. Model numbers are unique per microarchitecture.
