These can include extremes of workload, type of task, memory use, thermal load (heat), clock speed, or voltages. Memory and CPU are two components that are commonly stress tested in this way. There is considerable overlap between stress testing software and benchmarking software, since both seek to assess and measure maximum performance. Of the ...
Several tools with combined sampling and call-graph profiling. A set of visualization tools, VCG tools, uses the Call Graph Drawing Interface (CGDI) to interface with gprof. Another visualization tool that interfaces with gprof is KProf. Free/open source - BSD version is part of 4.2BSD and GNU version is part of GNU Binutils (by GNU Project) HWPMC
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.

It is also used in overclocking to test for system stability. [ 4 ] Although most [ 5 ] of its source code is available , Prime95 is not free and open-source software because its end-user license agreement [ 3 ] states that if the software is used to find a prime qualifying for a bounty offered by the Electronic Frontier Foundation , [ 6 ] then ...
The CPU's clock speed and VCore are automatically decreased when the computer is under low load or idle, to save battery power, reduce heat and noise. The lifetime of the CPU is also extended because of reduced electromigration, which varies exponentially with temperature. [1] The technology is a concept similar to Intel's SpeedStep technology.
CPU Performance; Memory Performance; Disk Performance (includes devices such as Solid-state drives) While running, the tests show only a progress bar and a "working" background animation. Aero Glass is deactivated on Windows Vista and Windows 7 during testing so the tool can properly assess the graphics card and CPU.
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.
