However, the instructions/cycle measurement depends on the instruction sequence, the data and external factors. IPS can be calculated using this equation: IPS = sockets × cores socket × clock × Is cycle 3 Millions of instructions per second (MIPS).2 Thousand instructions per second (TIPS/kIPS).Formerly TIPS was used occasionally for "thousand ips". The term is commonly used in association with a metric prefix (k, M, G, T, P, or E) to form kilo instructions per second ( kIPS), million instructions per second ( MIPS), and billion instructions per second ( GIPS) and so on. Because of these problems, synthetic benchmarks such as Dhrystone are now generally used to estimate computer performance in commonly used applications, and raw IPS has fallen into disuse. Memory hierarchy also greatly affects processor performance, an issue barely considered in IPS calculations. Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few branches and no cache contention, whereas realistic workloads typically lead to significantly lower IPS values. 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. Instructions per second ( IPS) is a measure of a computer's processor speed.
Computer processing efficiency, measured as the number of watts needed per million instructions per second (Watts per MIPS).
