However, Ivy Bridge lacks some newer power features like HWP (Hardware P-states) and C8/C9/C10 found in Skylake and later.
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.
Ivy Bridge uses HD 4000 graphics. A bad graphics driver can look like an ACPI failure to Windows. acpi genuineintel---intel64-family-6-model-58
Even though Model 58 is an older architecture, it remains highly capable for daily tasks and light gaming. To keep a "Family 6 Model 58" system running smoothly:
Notable processors with model 58:
This is Intel's "Super Family" for almost all modern consumer processors, spanning from the early Pentium Pro to today's Core i9 series.
Released in 2012, Ivy Bridge was a die shrink (from 32nm to 22nm) of the previous "Sandy Bridge" architecture, introducing Intel's then-revolutionary Tri-Gate (FinFET) 3D transistors. Popular desktop and mobile processors from this family include: However, Ivy Bridge lacks some newer power features
When Windows cannot catalog the ACPI sub-components of Model 58, it is missing the platform configuration file.
ACPI thermal zones ( _TZ ) may use model-specific critical trip points. A bad graphics driver can look like an
The "GenuineIntel---Intel64-Family-6-Model-58" designation is a specific identifier used within the ACPI framework to recognize Intel processors. This identifier is part of the ACPI _CPUID (Central Processing Unit Identifier) object, which provides information about the processor architecture, family, and model.
Released in mid-2012, Ivy Bridge was a crucial milestone in Intel’s historical "Tick-Tock" development strategy. It represented a "Tick," meaning it took the existing microarchitecture of the previous generation (2nd Gen Sandy Bridge) and shrunk the manufacturing process node down from 32nm to 22nm.
