CPU-Z is more comprehensive in virtually all areas compared to the tools provided in the Windows to identify various hardware components, and thus assists in identifying certain components without the need of opening the case; particularly the core revision and RAM clock rate. It also provides information on the system's GPU.

For example, on Intel Crystalwell CPUs, executing CPUID with EAX=4 and ECX=4 will cause the processor to return the following size information for its level-4 cache in EBX and ECX: EBX=03C0F03F and ECX=00001FFF - this should be taken to mean that this cache has a cache line size of 64 bytes (EBX[11:0]+1), has 16 cache lines per tag (EBX[21:12 ...
Microsoft Windows, for example, designates its 32-bit versions as "x86" and 64-bit versions as "x64", while installation files of 64-bit Windows versions are required to be placed into a directory called "AMD64". [20] In 2023, Intel proposed a major change to the architecture referred to as X86S (formerly known as X86-S). The S in X86S stood ...
An x86-64 processor acts identically to an IA-32 processor when running in real mode or protected mode, which are supported modes when the processor is not in long mode.. A bit in the CPUID extended attributes field informs programs in real or protected modes if the processor can go to long mode, which allows a program to detect an x86-64 processor.
The instructions below are those enabled by the BMI bit in CPUID. Intel officially considers LZCNT as part of BMI, but advertises LZCNT support using the ABM CPUID feature flag. [3] BMI1 is available in AMD's Jaguar, [5] Piledriver [6] and newer processors, and in Intel's Haswell [7] and newer processors.
AIDA64 is a system information, diagnostics, and auditing application developed by FinalWire Ltd (a Hungarian company) that runs on Windows, Android, iOS, ChromeOS, Windows Phone, Sailfish OS, Ubuntu Touch and Tizen operating systems. It displays detailed information on the components of a computer.
In the mid-1990s, a facility for supplying new microcode was initially referred to as the Pentium Pro BIOS Update Feature. [18] [19] It was intended that user-mode applications should make a BIOS interrupt call to supply a new "BIOS Update Data Block", which the BIOS would partially validate and save to nonvolatile BIOS memory; this could be supplied to the installed processors on next boot.
