For a fee, SPEC distributes source code files to users wanting to test their systems. These files are written in a standard programming language, which is then compiled for each particular CPU architecture and operating system. Thus, the performance measured is that of the CPU, RAM, and compiler, and does not test I/O, networking, or graphics.
CoreMark results can be found on the CoreMark web site, [4] and on processor data sheets. Results are in the following format: CoreMark 1.0 : N / C / P / M N Number of iterations per second (with seeds 0,0,0x66,size=2000) C Compiler version and flags; P Parameters such as data and code allocation specifics
SPEC was founded in 1988 and its membership comprises over 120 computer hardware and software vendors, educational institutions, research organizations, and government agencies internationally. SPEC benchmarks and tools are widely used to evaluate the performance of computer systems; the test results are published on the SPEC website.
The performance of a computer is a complex issue that depends on many interconnected variables. The performance measured by the LINPACK benchmark consists of the number of 64-bit floating-point operations, generally additions and multiplications, a computer can perform per second, also known as FLOPS. However, a computer's performance when ...
Instructions per second (IPS) is a measure of a computer's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.
The Whetstone benchmark is a synthetic benchmark for evaluating the performance of computers. [1] It was first written in ALGOL 60 in 1972 at the Technical Support Unit of the Department of Trade and Industry (later part of the Central Computer and Telecommunications Agency) in the United Kingdom.
iCOMP for Intel Comparative Microprocessor Performance was an index published by Intel used to measure the relative performance of its microprocessors.. Intel was motivated to create the iCOMP rating by research which showed that many computer buyers assumed that the clock speed – the “MHz” rating – was indicative of performance, regardless of the processor type. iCOMP ratings based on ...
