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.
This is done by defining a series of state-components, each with a size and offset within a given save area, and each corresponding to a subset of the state needed for one CPU extension or another. The EAX=0Dh CPUID leaf is used to provide information about which state-components the CPU supports and what their sizes/offsets are, so that the OS ...
CPUID model numbers are 30h-3Fh. AMD Excavator Family 15h (4th-gen) – fourth-generation Bulldozer (Final optimisation). CPUID model numbers are 60h-6Fh, later updated revisions have model numbers 70h-7Fh. AMD Zen – family of microarchitectures. The successor to Bulldozer. Included in the Ryzen and Epyc CPU lines.
Intel distributes microcode updates as a 2,048 (2 kilobyte) binary blob. [1] The update contains information about which processors it is designed for, so that this can be checked against the result of the CPUID instruction. [1] The structure is a 48-byte header, followed by 2,000 bytes intended to be read directly by the processor to be ...
Penryn is the code name of a mobile processor from Intel that is sold in varying configurations such as Core 2 Solo, Core 2 Duo, Core 2 Quad, Pentium and Celeron.. During development, Penryn was the Intel code name for the 2007/2008 "Tick" of Intel's Tick-Tock cycle which shrunk Merom to 45 nanometers as CPUID model 23.
This article lists software and hardware that emulates computing platforms. The host in this article is the system running the emulator, and the guest is the system being emulated. The list is organized by guest operating system (the system being emulated), grouped by word length .
Speccy, developed by Piriform Software, is a freeware utility software and runs under Microsoft Windows 11, Windows 10, Windows 8, Windows 7, Vista and XP for both IA-32 and x64 versions of these operating systems, [4] [5] which shows the user information about hardware and software of the computer.
Takes as input a CPUID leaf index in EAX and, depending on leaf, a sub-index in ECX. Result is returned in EAX,EBX,ECX,EDX. [e] Instruction is serializing, and causes a mandatory #VMEXIT under virtualization. Support for CPUID can be checked by toggling bit 21 of EFLAGS (EFLAGS.ID) – if this bit can be toggled, CPUID is present. Usually 3 [f]
