GPU chip computing power

1. As the name suggests, the mine calculation card is a graphics card used for mining. More strictly speaking, it is a graphics card used for mining with high load for a long time. The graphics card used in mining usually works at full load 24 hours a day for several months. In this way, PCB and electronic components will accelerate aging, affecting the life of components. Not counting the rest time of the graphics card, even if we play the game for 8 hours a day, the life of the mine card is only one third of that of the normal graphics card. It can be said that the general life of the mine card is only a few months.

2. The main reason for GPU's strong computing power is that most of its circuits are arithmetic units. In fact, adders and multipliers are relatively small circuits. Even if they do many such operation units, they will not occupy too much chip area. And because other parts of GPU occupy a small area, it can also have more registers and caches to store data. On the one hand, CPU is so slow because it has a large number of units for processing other programs, such as branch loops, and because CPU processing requires a certain degree of flexibility, the structure of arithmetic logic unit of CPU is also much more complex. In short, in order to improve the processing speed of branch instructions, many components of CPU are used to do branch prediction, and correct and recover the results of Alu when the branch prediction error occurs. These greatly increase the complexity of the device
in addition, the current CPU design is also learning from GPU, that is, adding floating-point operation units with parallel computing and not so many control structures. For example, Intel's SSE Instruction set can perform four floating-point operations at the same time, and many registers have been added. In addition, if you want to learn GPU computing, you can download a CUDA SDK, which has very detailed instructions

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

extended data

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

5. Computing power is a concept put forward by NVIDIA when it released CUDA (Compute Unified Device Architecture, a programming language for GPU, similar to C programming for CPU). Because the graphics card itself is a floating-point computing chip, it can be used as a computing card, so the graphics card has computing power. Different graphics cards have different computing power. In order to show the difference, NVIDIA put forward the corresponding version of computing power x.x on the procts of different periods. Computing power 1.0 appeared on early graphics cards, such as the original 8800 ultra and many 8000 Series cards, as well as Tesla C / D / s870s cards. Cuda1.0 was released corresponding to these graphics cards. Today, computing power 1.0 has been eliminated from the market. Then there was computing power 1.1, which appeared on many 9000 Series graphics cards. Computing power 1.2 appears together with GT200 Series graphics card, while computing power 1.3 is proposed when upgrading from GT200 to GT200 A / b revision. In the future, there will be computing power 2.0, 2.1, 3.0 and other versions. The latest released version is computing power 6.1, which is supported by the latest Pascal architecture graphics card. At the same time, CUDA version is also updated to cuda8.0

ordinary users do not need to care about the computing power of the graphics card, only GPU programmers care about this problem when they write CUDA programs to develop GPU computing. As long as you know the model of your computer's graphics card, you can find the corresponding computing power https://developer.nvidia.com/cuda-gpus .

you have to try Puqi's shark feast when you go to Yueqing. Shark feast is Puqi's main feature: shark skin, shark bone, shark whip, shark meat, shark belly, shark lip and other parts of the shark can be processed into dishes. Puqi ding'anmen restaurant is one of the more representative. There is a Puqi exit on Yong Tai Wen expressway, which is very convenient for both self driving and shuttle bus.

7. GPU is a concept relative to CPU, CPU is the central processing unit, GPU is the processor of graphics card, is the most important part of graphics card. GPU English full name graphic processing unit, Chinese translation for "graphics processor". GPU is the "brain" of graphics card, which determines the grade and most performance of graphics card.

GPU is a graphics processor, also known as display core, visual processor and display chip. It is a kind of microprocessor which is specially used to do image and graphics related operations on personal computers, workstations, game machines and some mobile devices (such as tablet computers, smart phones, etc.)

GPU makes the graphics card less dependent on CPU, and does part of the original CPU work, especially in 3D graphics processing, the core technology of GPU is hardware T & amp; L (geometry conversion and illumination processing), cubic environment material mapping and vertex blending, texture compression and bump mapping, al texture four pixel 256 bit rendering engine, and hardware T & amp; L technology can be said to be the symbol of GPU

{rrrrrrr}

extended materials:

the architecture of GPU can well solve the problems of transparency, high quality anti aliasing, motion blur, depth of field and micro polygon coloring, which need to be solved in film level image quality, and can well support more complex graphics algorithms such as real-time ray tracing and micro polygon coloring, It is also difficult to deal with the global illumination, dynamic and real-time display, shadow and reflection of high-quality real-time 3D graphics

with the rapid development of VLSI technology, the new generation of GPU chip has more powerful computing power, which can greatly improve the graphics resolution, scene details (more triangle and texture details) and global approximation
