What Is a CPU Benchmark Score and How Is It Interpreted?
A CPU benchmark score numerically expresses the performance a processor shows under a particular test method. These scores make it easier to compare different processors on a common measure.
For example, PassMark CPU Mark is one of the benchmark measures used to compare processors' overall computing performance. There are also tests that evaluate single-core performance.
How is a benchmark score interpreted?
The scores of two processors on the same benchmark test can be compared. The processor with the higher score performed better in that test. However, this does not mean it will run every piece of software faster by the same ratio.
For example:
- Processor A: 4,000 CPU Mark
- Processor B: 8,000 CPU Mark
Even though Processor B's score is twice as high, there is no guarantee that the real application will run twice as fast. How the software uses a single core or multiple cores, memory capacity, storage, graphics processing power and cooling conditions affect the result.
Why is benchmarking important when choosing an industrial PC?
A benchmark is useful for narrowing down many processors at the first stage and comparing performance classes. However, in the final choice, the application's real needs, the manufacturer's technical documents and, where possible, tests run on the software should be taken into account.
