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.
1990s. The 32-bit microprocessor dominated the consumer market in the 1990s. Processor clock speeds increased by more than tenfold between 1990 and 1999, and 64-bit processors began to emerge later in the decade. In the 1990s, microprocessors no longer used the same clock speed for the processor and the RAM.
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]
Cycles per instruction. In computer architecture, cycles per instruction (aka clock cycles per instruction, clocks per instruction, or CPI) is one aspect of a processor 's performance: the average number of clock cycles per instruction for a program or program fragment. [ 1] It is the multiplicative inverse of instructions per cycle .
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 ...
Comparison of Intel processors. As of 2020, the x86 architecture is used in most high end compute-intensive computers, including cloud computing, servers, workstations, and many less powerful computers, including personal computer desktops and laptops. The ARM architecture is used in most other product categories, especially high-volume battery ...
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 ...
For the linguistics term "question word", see Interrogative word. In computing, a word is the natural unit of data used by a particular processor design. A word is a fixed-sized datum handled as a unit by the instruction set or the hardware of the processor. The number of bits or digits [ a ] in a word (the word size, word width, or word length ...
