Acpi Genuineintel---intel64-family-6-model-58 Verified
Because this identifier is tied to ACPI, it often relates to how the laptop or desktop sleeps, hibernates, or throttles speed.
When the kernel initializes ACPI, it examines each processor object ( \PR_ or _SB_.PRxy ). The acpi_processor_get_info() function prints or matches the CPUID against ACPI IDs. You might see similar strings in:
Set the to 5% and the Maximum processor state to 99% (dropping it to 99% disables Intel Turbo Boost, which can instantly stabilize a degrading or overheating CPU).
This is the most hardware-specific part. Intel assigns a (major generation) and model (specific core design) to every processor. Family 6 has been used since the Pentium Pro (1995) for almost all recent Intel Core, Xeon, Atom, and Celeron processors. Model 58 (decimal) or 0x3A (hex) corresponds to:
This string is a hardware ID used by your operating system to communicate with your processor. Behind this technical jargon lies one of Intel's most successful processor architectures. Decode the Hardware ID acpi genuineintel---intel64-family-6-model-58
: This corresponds to the processor's "Family" model from the CPUID instruction. For decades, nearly all modern Intel Core processors (from the original Core series to the latest generations) have belonged to Family 6 . This is a crucial fact for kernel developers and is the reason we see family-6 so frequently in IDs for Intel processors.
This stands for Advanced Configuration and Power Interface. It is the bridge between the hardware and the operating system, allowing your software to tell the hardware when to sleep, wake up, or throttle power to save battery. GenuineIntel / Intel64:
You are most likely to encounter acpi genuineintel---intel64-family-6-model-58 in the following scenarios:
The acpi genuineintel---intel64-family-6-model-58 ID isn't something you typically interact with daily, but it appears in specific places: Because this identifier is tied to ACPI, it

Introduced as the "Tick" phase in Intel's classic "Tick-Tock" manufacturing paradigm, Model 58 miniaturized the prior 32nm Sandy Bridge architecture to a 22nm die size. This specific family introduced several technical breakthroughs.
As of 2024, Model 58 (Ivy Bridge) is considered legacy hardware.
The string acpi genuineintel---intel64-family-6-model-58 is an unusual but decipherable artifact that points to an being handled by the ACPI subsystem in a Linux environment, possibly with a formatting quirk. It reminds us of the deep integration between CPU microarchitecture, ACPI firmware tables, and the OS kernel. You might see similar strings in: Set the
To understand what this identifier means, we have to break it down into its four distinct components:
To see your CPU’s family-model:
"acpi genuineintel---intel64-family-6-model-58"
It looks like you’ve provided a string that resembles a , likely extracted from a Linux system log ( dmesg , lscpu , or /proc/cpuinfo ), or from an ACPI/DSDT table.
