Is there a big difference between quad core 1 2Hz and quad core 1 7Hz?

The same type of CPU from the same manufacturer, the difference is still relatively large. It is difficult to judge the difference between different manufacturers and different types from the main frequency.

To take a correct view of the CPU clock speed, the CPU clock speed is the clock speed at which the CPU core works. The main frequency 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, in some cases, it is likely that the actual computing speed of the CPU with a higher frequency will be lower.

A more realistic example is Intel and AMD, many AMD CPUs are much higher than Intel's, but the performance is sometimes inferior to Intel's CPUs.

If it's the same process, the same architecture, the quad-core is good, if it's not the same process and the same architecture, it's another matter, according to the mobile phone model you gave, 2S uses Qualcomm APQ, 1C is MediaTek, 2S CPU performance is much stronger than 1C CPU,

Hello, the quad-core is fast (but the processor does not represent the entire phone), other different configurations of the mobile phone will also determine the speed of the mobile phone, memory, firmware are very important, and the running memory reaches 2G to give full play to the performance of the quad-core, but there are exceptions, Intel's atom mobile phone dual-core can also kill the general quad-core in seconds.

The speed alone is much worse.

and the difference

1. Generally, the higher the main frequency, the faster the CPU can process data, and the total computing speed of the CPU also depends on the performance indicators of the CPU's pipeline, bus and other aspects, so there is no direct comparison between the frequency and the level.

2. Process improvement, architecture improvement, and algorithm improvement cause differences in CPU performance.

3. CPU frequency increase vulnerability.

If the architecture is the same, it must be great, as for different architectures, it is necessary to compare the synthesis of efficiency and frequency, the architecture and process are the same, and the frequency of different CPUs will be different for different models.

4. The performance of the CPU with high frequency will be more prominent, because the performance is basically increased linearly according to the frequency, so how much the frequency increases, the performance will basically increase.

<> as shown in the figure above, the i9-9980HK is not only stronger than the i7-8700 in terms of the number of cores and threads, but also in the turbo frequency.

The upper i9-9980HK is also higher than the i7-8700. Normally, CPUs will run at turbo frequencies. Therefore, the base frequency can be disregarded.

In terms of power consumption, the i9-9980HK is also 20W lower than the i7-8700. So the conclusion is that the i9-9980HK is better.

All other things being equal, the higher the frequency, the better.

First, the number of cores is different.

1. Quad-core Hz: with four computing cores.

2. Dual-core HZ: with two computing cores.

Second, the main frequency is different.

1. Quad-core Hz: The clock frequency per second is 100 million times.

2. Dual-core Hz: The clock frequency per second is 100 million times.

Third, the advantages and disadvantages are different.

1. Quad-core Hz: It also consumes a lot of power, but the ability to process data at the same time is also greatly enhanced.

2. Dual-core Hz: less power consumption, lower processing power than quad-core.

Compared with CPU quad-core Hz and dual-core Hz, the higher the CPU frequency, the faster the running speed, but the quad-core CPU is equivalent to having four cores running at the same time, while the dual-core only has two cores, so the quad-core is faster when running.

The difference between CPU quad-core and dual-core is that single-core refers to one core in a processor, while multi-core processor refers to the integration of multiple complete computing cores in one processor, and dual-core is divided into dual-core and dual-threaded, dual-core four-thread, four-core eight-thread, four-core and four-thread, so the CPU performance of the same core is very different from the above.

In accordance with the relationship between priority and priority.

Criticality ordering: manufacturing process, core architecture, pipeline progression, main frequency, and L2 cache.

In the same area, the 90nm manufacturing process can accommodate 50% more transistors than the 45nm manufacturing process, which can greatly reduce heat generation and improve the key to processor performance.

The lower the pipeline order, the shorter the data processing process, and the faster the processing speed is the more times it is processed in the same clock cycle.

A large L2 cache increases processing efficiency by dramatically reducing the number of times the CPU accesses memory to speed up processing. On the other hand, if the L2 cache is too small, the CPU needs to access the speed from memory frequently, and the processing speed will be reduced.

In processors with the same core architecture, the main frequency plays a key role, accounting for 70% of the key factors of processor speedL2 cache accounts for 20%, other factors account for 10%, the main frequency is like the speed of a car, the higher the frequency of the processor, the more data can be processed under the same clock cycle, under the same data, the faster the processing speed.

It is the same project that handles a 10G amount of computing, and the 4 cores are time.

Dual-core is 5 times at a time, so to speak.

Then in the decompression, the speed ratio is faster because of the high frequency of the operation.

The main frequency is different, the core is different, don't you know it yourself?

This is the octa-core configuration of the mobile phone processor.

Use four big cores and use them with four small cores.

In this configuration, the power consumption can be well controlled. When the demand is not high, it can be dealt with by just starting a small core.

There are false octa-cores and true octa-cores. The power consumption of the false octa-core control is not as good as that of the true octa-core control.

A simple analogy. Each of the four people writes a word per second. Eight people each write a word per second.

Each core can be reached, which is equivalent to a single core, and in reality it will be slightly lower than a single core. The performance is very powerful, the mobile phone must be enough, the fluency will be very powerful in all aspects, and LZ should consider the battery more. Hehe.

Although the two codes look similar, in fact, the 410 and 400 processors are quite different internally, but the positioning of the 410 in Qualcomm's product line is to replace the low-end processor of the 400, so it follows the code name of 4x0. The 400 is a quad-core A7 architecture, and the 410 is Arm's new A53 architecture, which is 64-bit. A53The efficiency is about three percent higher than that of A7,The key is to reduce power consumption,The efficiency is of course stronger than 400,The downstairs is purely ,,, forget it.

Samsung's theoretical efficiency is higher,Cortexa15The core performance is extremely strong,Even more than the Krait300Qualcomm Snapdragon600 processor of the architecture,But this dual quad-core also has the bug of excessive heat,Relatively speaking, Qualcomm is much more normal,And both are very strong,The actual user experience is basically the same,I personally recommend Qualcomm this,The performance is a little worse,But it is more stable,Less calorific。

If you are consulting about the S4 series mobile phone, the model of dual SIM dual mode dual pass dual quad core is i9502. Dual quad-core is quad-core + quad-core Note: Depending on the degree of task load, the quad-core or quad-core processor is enabled at a time-sharing basis. Both processors do not execute at the same time.

Hope it helps you and have a great day!

But look at the data, of course, it's quad-core, and the rest has the architecture, heat dissipation or something.

The Snapdragon 600 is good, the technical optimization is in place, the smoothness is good, and unlike Exynos, the power consumption is large and the heat is large.

Not necessarily,Look at what the other party's eight cores are.,But look at the main frequency.,It's not very good.。

There are many ways to measure a processor:

1.The production process: The 14nm Exynos 7420 is much better than the 20nm Snapdragon 810.

2.Number of cores. Not absolutely, just like the quad-core Snapdragon 820 is faster than the eight-core MT6795 (Helio X10), or even two levels.

3.Optimization of the manufacturer. In terms of heat dissipation, balance, etc., we must do a good job of optimization.

There are so many more, I won't list them all.

Please complete your questions before asking them.

However, it is not recommended to have Snapdragon 400 series chips, after all, it is 2016, the price-efficiency ratio of mobile phones is getting higher and higher, and you can buy a flagship-level processor for seven or eight hundred yuan, and 410 seems outdated.

The 410 is better, the 400 is a small horse-drawn cart, and the 410 is a large horse-drawn cart, so the latter is faster.

The octa-core is a Qualcomm Snapdragon 660AIE octa-core processor, which is a low-end processor compared to other processors. The octa-core is a first-class processor, including operation logic components, register components and control components, etc., and has the functions of processing instructions, performing operations, controlling time, and processing data.

Extended Qualifications:**Since its inception, the processing car side device has made great progress in logical structure, operation efficiency and functional extension. Register components, including general-purpose registers, specialized registers, and control registers.

General-purpose registers can be divided into two types: fixed-point and floating-point, which are used to store the temporary storage of register operations and intermediate (or final) operation results during instruction execution.

General-purpose registers are an important part of the processor, and most instructions need to access them. The width of the general register determines the width of the data path inside the closed answering machine, and the number of ports can often affect the parallelism of the internal operation.
