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.
As an example, a dual-core Westmere processor capable of hyperthreading (thus having two cores and four threads in total) could have x2APIC ids 0, 1, 4 and 5 for its four logical processors. Leaf Bh (=EAX), subleaf 0 (=ECX) of CPUID could for instance return 100h in ECX, meaning that level 0 describes the SMT (hyperthreading) layer, and return ...
To keep costs low on high-volume competitive products, the CPU core is usually bundled into a system-on-chip (SOC) integrated circuit. SOCs contain the processor core, cache and the processor's local data on-chip, along with clocking, timers, memory (SDRAM), peripheral (network, serial I/O), and bus (PCI, PCI-X, ROM/Flash bus, I2C) controllers.
The XSAVE instruction set extensions are designed to save/restore CPU extended state (typically for the purpose of context switching) in a manner that can be extended to cover new instruction set extensions without the OS context-switching code needing to understand the specifics of the new extensions.
The Time Stamp Counter was once a high-resolution, low-overhead way for a program to get CPU timing information. With the advent of multi-core/hyper-threaded CPUs, systems with multiple CPUs, and hibernating operating systems, the TSC cannot be relied upon to provide accurate results — unless great care is taken to correct the possible flaws: rate of tick and whether all cores (processors ...
The core is compatible with the older PowerPC Book E specification as well as the Power ISA v.2.03. [ citation needed ] It has a dual issue, seven-stage pipeline with FPUs (from version 2 onwards), 32/32 KiB data and instruction L1 caches and 256, 512 or 1024 KiB L2 frontside cache.
Yonah is the code name of Intel's first generation 65 nm process CPU cores, based on cores of the earlier Banias (130 nm) / Dothan (90 nm) Pentium M microarchitecture.Yonah CPU cores were used within Intel's Core Solo and Core Duo mobile microprocessor products.
A combined caching and home agent (CHA) handles resolution of coherency across multiple processors, as well as snoop requests from processor cores and local and remote agents. Separate physical CHAs are placed within each processor core and last level cache (LLC) bank to improve scalability according to the number of cores, memory controllers ...
