Acpi Genuineintel---intel64-family-6-model-58 -

By combining Model 58 with the Stepping (revision) number, we can identify specific processors. The vast majority of Model 58 CPUs have a Stepping of 9. They encompass a wide range of Intel's 2012-2013 lineup, including many desktop and laptop CPUs:

Ivy Bridge (22 nm, 3rd generation Core i3/i5/i7, Xeon E3-12xx v2)

Used by Intel for nearly all modern microarchitectures descended from the original Pentium Pro/Pentium II lineage. Specific CPU Generation

ACPI is supported by most modern operating systems, including Windows, Linux, and macOS. The operating system uses ACPI to interact with hardware components, manage power consumption, and configure system settings.

Occasionally, users encounter this ID in a problematic context. Here are a few common scenarios: acpi genuineintel---intel64-family-6-model-58

Thus, the pattern is permanent. If you are writing scripts or log parsers that match this string, like:

Understanding each segment—ACPI, vendor string, 64-bit capability, and family-model-stepping—is a valuable exercise for any systems engineer working on x86 power management, hypervisors, or kernel debugging. While the dashes are anomalous, the underlying hardware is solid, well-documented, and widely deployed.

ACPI (Advanced Configuration and Power Interface) By combining Model 58 with the Stepping (revision)

Thus, the string appears during the acpi_processor_add() function when the kernel prints:

The ACPI\ prefix reveals that the system's Unified Extensible Firmware Interface (UEFI) or BIOS exposed this device profile directly to the OS kernel. Rather than interacting raw with the underlying processor silicon, Windows coordinates through the standardized ACPI layer. This layer manages deep power-saving states (C-states), operating frequencies (P-states), and core parking strategies. 2. GenuineIntel & Intel64

While ACPI and the GenuineIntel---Intel64-Family-6-Model-58 identifier play crucial roles in modern computer systems, there are challenges and limitations to consider: Specific CPU Generation To see your CPU’s family-model:

Newer CPUs (Skylake, Family 6 Model 94; Cascade Lake, Model 85; Alder Lake, Model 151) produce similar strings, e.g.:
