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

In Windows, processors are identified by their CPUID. The "Family 6 Model 58" identifier points specifically to: Ivy Bridge (22nm). Release Date: Primarily 2012–2013.

architecture. It is typically found in the Device Manager or system logs when a driver is missing or being identified. Technical Breakdown

In Linux kernel source code (specifically in arch/x86/kernel/cpu/intel.c and drivers/acpi/processor_driver.c ), this string is generated when the ACPI processor driver matches a detected CPU against its internal tables. It is ; it is a debug or identification token used to apply model-specific quirks and power management policies. acpi genuineintel---intel64-family-6-model-58

: Ivy Bridge introduced native support for PCIe 3.0, doubling the bandwidth for discrete graphics cards and high-speed storage compared to PCIe 2.0. Intel HD Graphics 4000/2500 : Featured a much-improved integrated GPU with support for DirectX 11 , OpenGL 4.0, and OpenCL 1.2. DDR3L Support

A: Yes. Virtualization software emulates an ACPI environment for the guest OS. The virtual CPU provided to the guest will often have a consistent Family 6 Model string regardless of the host's actual CPU to ensure compatibility. This allows a VM to run on vastly different hardware without the OS noticing. In Windows, processors are identified by their CPUID

The string follows the standardized format utilized by the Windows Plug and Play (PnP) manager and the subsystem. Breaking down the string reveals how the operating system classifies the physical processor:

If you ever encounter this string in your logs, take a moment to appreciate the decades of standards (ACPI, CPUID, x86-64) that silently work together—most of the time, perfectly. architecture

Run dmesg | grep -i "acpi genuineintel" and you might see it during CPU enumeration. It is normal and harmless.

x86-64, MMX, SSE4.2, AVX, AES-NI, and F16C. Representative Processors

While it looks like a line of code from a sci-fi movie, it’s actually a very specific "ID card" for your computer's brain. Let’s break down what this means and which processor you likely have. The Anatomy of the String

A: All modern operating systems (Windows, Linux, macOS) use ACPI to interact with hardware. They read these IDs from ACPI tables to load the correct processor driver and manage power features. The identifier is a fundamental part of the Plug and Play system.
