CPU and graphics computing power

1.

Main differences between CPU and GPU:

1. CPU is the central processing unit of computer

GPU is the graphics processor of computer

CPU is a very large-scale integrated circuit, which includes Alu arithmetic logic unit, cache memory and bus

CPU is the core of a computer's control and operation, its main function is to interpret the instructions issued by the computer and process the big data in the computer software

GPU is the abbreviation of image processor. It is a kind of microprocessor which is specially used for PC or embedded device to perform image operation

The work of GPU is similar to that of CPU mentioned above, but not entirely. It is designed to perform complex mathematical and geometric calculations. This game has high requirements in this respect, so many game players also have deep feelings for GPU

so CPU and GPU are two completely different things, they just sound the same

extended data:

CPU and GPU are different in design because they are used to deal with different tasks at first, and some tasks are similar to the problems that GPU is used to solve at first, so we use GPU to calculate. The operation speed of GPU depends on how many pupils are employed, and the operation speed of CPU depends on how powerful professors are employed, The professor's ability to deal with complex tasks is very good, but for less complex tasks, it still can't hold many people

of course, today's GPU can also do some slightly complicated work, which is equivalent to upgrading to the level of junior high school students and senior high school students, but it still needs CPU to feed data to the mouth before it can start to work, which is still managed by CPU

CPU: central processing unit, is a very large scale integrated circuit, is a computer operation core (core) and control unit (control unit). Its main function is to interpret computer instructions and process data in computer software

GPU: graphics processor, also known as display core, visual processor and display chip, is a kind of microprocessor which is specialized in image operation on personal computers, workstations, game machines and some mobile devices (such as tablet computers, smart phones, etc.)

CPU and GPU are designed for two different application scenarios respectively

1. CPU needs strong versatility to deal with different data types, and at the same time, it also needs logical judgment, which will introce a lot of branch jump and interrupt processing. All these make the internal structure of CPU extremely complex

GPU is faced with highly unified, interdependent large-scale data and pure computing environment without interruption

application direction of CPU and GPU

GPU is suitable for high predictability and a large number of similar operations, as well as high latency and high throughput architecture operations

3. There are many differences between integrated graphics card and independent graphics card in terms of CPU utilization rate and memory utilization rate. Understanding the differences and advantages and disadvantages between them will help us to have a definite aim when we choose graphics card. The main differences are as follows:

1: CPU occupancy rate independent graphics card has its own GPU, a lot of image processing does not need to be done by CPU, saving CPU time; Integrated graphics card uses CPU to calculate image data for you, which takes up part of CPU resources

2: graphics computing power: the graphics computing power of independent graphics card is much better than that of integrated graphics card, because when playing 3D games, it needs a lot of complex computing, so the integrated graphics card is not able to do it. In order to exchange for smooth game speed, we have to sacrifice the image quality

Three: memory utilization: independent graphics card comes with its own graphics memory, while integrated graphics card needs to take part of the system memory as graphics memory, so it is better to eat memory. If the memory capacity of the machine with integrated graphics card is not large, the running data will be slower than that of the independent graphics card

Four: the running frequency of the integrated graphics card of rendering pipeline is similar to that of the independent graphics card of the same level, and the high-quality graphics card can also exceed the frequency; But the biggest disadvantage of the integrated graphics card is that its rendering pipeline is much less than that of the independent graphics card. Generally, there are only one or two pipelines, which limits the display of the graphics card, so its basic performance is not as good as that of the independent graphics card< As far as the problem is concerned, the independent graphics card is separated from the motherboard and inserted into the AGP pciex16 slot, while the integrated graphics card is attached to the motherboard as the name suggests. The integrated graphics card integrates the display chip into the motherboard, and the video memory is shared in the physical memory. The independent graphics card is inserted in PCI, AGP, pciex16 slots, with independent display chip and memory

VI: the price of integrated graphics card motherboard is cheaper than that of independent graphics card + motherboard.

4. CPU is equivalent to a doctor, GPU is equivalent to 10000 primary school students, primary school students can't do difficult math problems, but can do a lot of basic operations at the same time, and CPU can't calculate 10000 addition and subtraction methods at a time, but can solve the problems that GPU can't calculate

5. The first floor is a detour
generally speaking, for the same level of medicine, the increase of experience is relatively small, and for the higher level of experience, the failure rate is too high. So try to do a higher level
Level 1, make magic crystal to 220 (bright rose and luminous pearl, very cheap)
then make the primary protein oil (grade 2 medicine, thick meat and small blue crystal), 255 at a time, and it will probably rise to more than grade 4
then you can make intermediate protein oil or other drugs to achieve level 5 (just to level 5)
after level 5, ask the enchanter to help you proce 255 black magic procts (255 magic crystals and small black crystals)
then change 255 sharp eye potions (3 small red crystals are changed at Norton), and make 255 eagle eye potions (black magic procts and sharp eyes) at one time
after that, level 7 will be finished directly
the price of the primary protein oil and eagle eye potion is definitely higher than your cost.

6. The fortress has reached level 2, and the mission level has reached level 98. Then there are drawings for sale in the fortress. The price is 750 gold coins. Or to the main city of Delano, you can exchange books for books, which are obtained by doing tasks.

7. Alchemy 300 is needed, and the most convenient place is shatas City
slum
there are crow people teaching on the platform of the northernmost tree.

8. Go to play Warcraft and alchemy

Different uses are not the same, for example:

1. Game uses: for most large-scale games, the main focus is on independent graphics card, so when buying a computer, graphics card is often the most important. Most large-scale 3D games require very fine pictures.

for example, surface subdivision, volume illumination, dynamic particle illumination, complex smoke simulation, and the hair of the characters can be displayed delicately. As far as the stand-alone masterpiece undertaking a large number of anti aliasing, depth of field and shadow calculation tasks is concerned, the role of the graphics card is self-evident

Professional graphic design and 3D modeling purposes: professional graphic design is divided into 2D design, 3D design, etc. Generally speaking, 2D design software such as Photoshop has little demand for display, but it is a great test of the computer's reading and storage speed, so it has higher requirements for CPU processing ability and hard disk reading and writing ability

< H2 > extended data:

there is a big difference between CPU and graphics card in the emphasis of function:

processor is suitable for complex operations with strong context relevance and more logical judgments; Graphics card is suitable for processing a large number of operations with weak correlation

for example, the physical effects in the game and the number of characters on the same screen mainly depend on the CPU, while the surface subdivision, volume illumination, dynamic particle illumination, complex smoke simulation and so on mainly depend on the GPU

the situation in the real environment may be more complicated than the previous one. For example, some games with poor optimization will still get stuck even if they are played by the best CPU and graphics card, while changing a solid-state hard disk may improve the experience more obviously. However, some graphics software that does not involve 3D rendering, such as Photoshop, does not require too much configuration. As long as the memory is sufficient, the high or low configuration will not bring the difference in experience
