Instructions per second. 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.
Core i7, on the desktop platform no longer supports hyper-threading; instead, now higher-performing core i9s will support hyper-threading on both mobile and desktop platforms. Before 2007 and post-Kaby Lake, some Intel Pentium and Intel Atom (e.g. N270, N450) processors support hyper-threading. Celeron processors never supported it.
Clock rate. Microprocessor clock speed measures the number of pulses per second generated by an oscillator that sets the tempo for the processor. It is measured in hertz (pulses per second). In computing, the clock rate or clock speed typically refers to the frequency at which the clock generator of a processor can generate pulses, which are ...

In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be ...
Instructions per cycle. In computer architecture, instructions per cycle ( IPC ), commonly called instructions per clock, is one aspect of a processor 's performance: the average number of instructions executed for each clock cycle. It is the multiplicative inverse of cycles per instruction. [ 1][ 2][ 3]
FLOPS. Floating point operations per second ( FLOPS, flops or flop/s) is a measure of computer performance in computing, useful in fields of scientific computations that require floating-point calculations. [ 1]
If the processor has the 5 steps listed in the initial illustration (the 'Basic five-stage pipeline' at the start of the article), instruction 1 would be fetched at time t 1 and its execution would be complete at t 5. Instruction 2 would be fetched at t 2 and would be complete at t 6. The first instruction might deposit the incremented number ...
