This range of capabilities, specifically in this case the number of CPUs, means that the SPEC INT benchmark is usually run on only a single CPU, even if the system has many CPUs. If a single CPU has multiple cores, only a single core is used; hyper-threading is also typically disabled,
A single-core processor is a microprocessor with a single CPU on its die. [1] It performs the fetch-decode-execute cycle one at a time, as it only runs on one thread . A computer using a single core CPU is generally slower than a multi-core system.
It uses a scoring system that separates single-core and multi-core performance, [7] [8] and workloads designed to simulate real-world scenarios. [9] The software benchmark is available for macOS, Windows, Linux, Android and iOS. Free users are required to upload test results online in order to run the benchmark.
Taken together, these practices are called bench-marketing. Ideally benchmarks should only substitute for real applications if the application is unavailable, or too difficult or costly to port to a specific processor or computer system. If performance is critical, the only benchmark that matters is the target environment's application suite.
A process with two threads of execution, running on a single processor . In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution.
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.

CoreMark draws on the strengths that made Dhrystone so resilient - it is small, portable, easy to understand, free, and displays a single number benchmark score. Unlike Dhrystone, CoreMark has specific run and reporting rules, and was designed to avoid the well understood issues that have been cited with Dhrystone .
