Acpi Genuineintel---intel64-family-6-model-158 !!install!! [ UPDATED ✰ ]

Given the model number, the OS can infer support for the following feature sets without directly executing CPUID leaf 7, though CPUID remains authoritative:

ACPI uses this identifier to load correct power management drivers, negotiate sleep states, and apply model-specific workarounds. For enthusiasts and system administrators, knowing this string helps diagnose throttling issues, BIOS bugs, and idle power problems.

So when ACPI reports family-6-model-158 , the OS knows it’s dealing with a 14nm++ chip with Speed Shift, Turbo Boost 2.0/3.0, and specific C-state latencies. acpi genuineintel---intel64-family-6-model-158

The "Family" number is a classification code used by Intel to group processor generations.

Common processors carrying this specific ID include: Given the model number, the OS can infer

In the world of Intel silicon, Model 158 (9E) specifically identifies members of the and Coffee Lake families.

| Model (decimal) | Model (hex) | Microarchitecture | Cores / Generation | Example SKUs | |----------------|-------------|-------------------|--------------------|---------------| | 158 | 0x9E | (14nm++) | 2 to 4 cores, Gen 8th/8th Gen refresh | Core i5-8250U, i7-8550U, i3-8130U, i7-8665U, Pentium Silver N5000? (No, that’s separate) | The "Family" number is a classification code used

In this long-form article, we will dissect every component of this identifier, explain the technology behind it (ACPI, CPUID, Intel64, Family, Model), reveal exactly which CPU “Model 158” refers to, and explore why the operating system needs this information for power management, thermal control, and performance optimization.
