The main frequency of the CPU, that is, the clock frequency at which the CPU core works.

cpu clock speed）。It is usually said that how many megahertz is a certain CPU, and this number of megahertz is the "main frequency of the CPU". The higher the frequency, the faster the CPU will operate.

However, the clock speed is not equal to the number of instructions that the processor can execute in one second, because the execution of an instruction may take multiple clock cycles.

For the CPU, under the premise of compatibility, the main thing depends on its speed, and the higher the main frequency, the longer the bytes, the faster the CPU speed.

The main frequency of the CPU is the clock frequency at which the CPU core works, generally in MHz or GHz. Many people think that the main frequency of a CPU is its operating speed, but this is not the case. The main frequency of the CPU indicates the speed of the digital pulse signal** in the CPU, which is not directly related to the actual computing power of the CPU.

There is a certain relationship between the main frequency and the actual computing speed (in the same series of computers, under the same conditions, the higher the main frequency, the faster the speed), but there is no definite formula to quantify the numerical relationship between the two, because the computing speed of the CPU also depends on the performance indicators of the CPU pipeline (cache, instruction set, CPU bits, etc.).

CPU calculations at a frequency similar to that of frames.

The main frequency of the CPU, the higher the main frequency, the faster the computing speed.

The main frequency is a performance indicator that reflects the speed of the computer's CPU. The clock frequency of the CPU is the clock frequency.

The operation of the computer is signaled in the clock.

The operation is performed step by step, and each clock signal cycle completes a one-step operation.

There is a certain relationship between the main frequency and the actual computing speed, but there is no definite formula to quantify the numerical relationship between the two, because the computing speed of the CPU also depends on the performance indicators of all aspects of the CPU pipeline (cache, instruction set.

number of bits of the CPU, etc.). Since the main frequency does not directly represent the computing speed, in some cases, it is likely that the actual computing speed of the CPU with a higher frequency will be lower.

Restrictions

Increasing the working frequency of the CPU is mainly limited by the production process. Since the CPU is made on a semiconductor silicon wafer, the wires need to be connected between the components on the silicon wafer, and the finer and shorter the wires are required in the high-frequency state, so as to reduce the spurious interference such as the distribution capacitance of the wires to ensure that the CPU calculation is correct. Therefore, the limitation of Likai's manufacturing process is the CPU frequency.

The dominant frequency of the CPU represents the digital pulse signal within the CPU.

**The speed is not directly related to the actual computing power of the CPU.

Since the main frequency does not directly represent the computing speed, it is likely that the actual computing speed of the CPU with a higher frequency will be lower under certain circumstances. The overall running speed of the computer not only depends on the CPU operation speed, but also related to the operation of other subsystems.

The main performance indicators of the computer are:

1) Computing speed. Computing speed is an important measure of computer performance.

2) Word length. Generally speaking, a computer processes the number of binary bits at the same time.

3) Access cycle: The time it takes for a memory to perform a "read" or "write" operation is called the memory access time (or read and write time), and two independent "read" or "write" operations (such as two consecutive "read" operations) are initiated

The minimum time required is called the access cycle (or storage cycle) 4) Computing speed: refers to the number of instructions that the computer can execute per second, generally in mips.

5) Capacity: One of the factors that measure the performance of a memory is its capacity, which is usually 2GB or 4GB of memory as standard in laptops.

6) Main frequency: refers to the clock frequency of the computer, and the unit is expressed in MHz.

1 word long. Word length refers to the number of bits of binary data that a computer's CPU can directly process.

2 Clock frequency refers to the clock frequency of the computer's CPU. The main unit is megahertz or gigahertz.

3. Calculation speed. The speed of a computer is usually described in millions of seconds.

Computer speed, word length, storage cycle, storage capacity.

1. Computing speed: Computing speed is an important indicator to measure computer performance. It is commonly referred to as computer computing speed (average computing speed), abbreviation for the average execution speed of single-word long fixed-point instructions, and the number of millions of machine language instructions processed per second.

This is a measure of CPU speed. For example, an Intel80386 computer can process 3 million to 5 million machine language instructions per second, which means that we can say that 80386 is a CPU with 3 to 5 MIPS.

2. Word length: In the field of computers, for a specific computer design, a word is a term used to represent its natural data unit, and it is used to indicate a fixed length of one-time processing transactions. The number of bits of a word, i.e., the length of the word, is an important feature in the structure of a computer system.

Word length is reflected in many aspects of computer structure and operation. The size of most registers in a computer is one word length. Typical values processed by computers may also be in terms of word length.

3. Access cycle: The time required for a memory to perform a "read" or "write" operation is called the access time (or read and write time) of the memory, and the shortest time required to start two independent "read" or "write" operations (such as two consecutive "read" operations) is called the access cycle (or storage cycle).

4. Storage capacity refers to the amount of binary information that can be contained in the memory, which is expressed by the product of the addressing number of the storage address register mar and the number of stored word digits in the memory.

The clock frequency of the CPU is used to measure the performance of the computer, which is referred to as MHz.

The clock frequency of the CPU is the main frequency, and the operation of the computer is carried out step by step under the control of the clock signal, and each clock signal cycle completes a one-step operation, and the clock frequency largely reflects the speed of the CPU.

It is usually said that how many megahertz is a certain CPU, and this number of megahertz is the "main frequency of the CPU". Many people think that the main frequency of a CPU is its operating speed, but this is not the case. The main frequency of the CPU indicates the speed of the digital pulse signal** in the CPU, which is not directly related to the actual computing power of the CPU.

Since the main frequency does not directly represent the computing speed, under a certain circumstance, it is likely that the actual computing speed of the CPU with a higher frequency will be lower. The overall running speed of the computer not only depends on the CPU computing speed, but also related to the operation of other subsystems.

Introduction to clock frequency

Clock frequency refers to the basic frequency of the clock in the synchronous circuit, which is measured by "several cycles per second", and the unit of measurement is the SI unit hertz (Hz). It is an important indicator of CPU performance.

Generally speaking, the higher the value of the main frequency, the better.

Frequency is a measurement name that describes the number of pulses that occur in a unit of time for a periodic cyclic signal (including a pulse signal); The standard unit of measurement for frequency is Hz (Hertz). The system clock in a computer is a typical pulse generator with a fairly accurate and stable frequency. Frequency is denoted by "f" in mathematical expressions, and its corresponding units are:

Hz (Hertz), KHZ (Kilohertz), MHz (Megahertz), GHz (Gigahertz).

Answer]: C frequency refers to the clock frequency of the computer before the coincident, that is, the average number of operations of the CPU in the mode clearing unit time (seconds), which is an important indicator to determine the speed and width of the computer, and is measured in megahertz (MHz).
