Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few branches, whereas realistic workloads consist of a mix of instructions and applications, some of which take longer to execute than others. The performance of the [[memory hierarchy]] also greatly affects processor performance, an issue barely considered in MIPS calculations. Because of these problems, various standardized tests, often called [[benchmark (computing)| "benchmarks"]] for this purpose -- such as [[SPECint]] -- have been developed to attempt to measure the real effective performance (often called "benchmark" for this purpose) in commonly used applications.

Processing performance of computers is increased by using [[multi-core processor]]s, which essentially is plugging two or more individual processors (called ''cores'' in this sense) into one [[integrated circuit]].<ref name="tt">{{Cite web
