CPU-Z is a freeware system profiling and monitoring application for Microsoft Windows and Android that detects the central processing unit, RAM, motherboard chipset, and other hardware features of a modern personal computer or Android device.
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 ...
System monitoring software like SpeedFan on Windows, lm_sensors on Linux, envstat on NetBSD, and sysctl hw.sensors on OpenBSD and DragonFly can interface with these chips to relay this environmental sensor information to the user.
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.
TechPowerUp GPU-Z (or just GPU-Z) is a lightweight utility designed to provide information about video cards and GPUs. [2] The program displays the specifications of Graphics Processing Unit (often shortened to GPU) and its memory; also displays temperature, core frequency, memory frequency, GPU load and fan speeds.
Based on the K7 but was designed around a 64-bit ISA, added an integrated memory controller, HyperTransport communication fabric, L2 cache sizes up to 1 MB (1128 KB total cache), and SSE2. Later K8 added SSE3. The K8 was the first mainstream Windows-compatible 64-bit microprocessor and was released April 22, 2003.
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.
The number of available hardware counters in a processor is limited while each CPU model might have a lot of different events that a developer might like to measure. Each counter can be programmed with the index of an event type to be monitored, like a L1 cache miss or a branch misprediction.
