How much computing power is computer CPU

1. There is no way to estimate the total computing power of computers all over the world, because everyone's computers, including CPUs, graphics cards and memory, are different. To calculate the total computing power of the world, I don't think anyone can do it.

2. The floating-point computing power of single processor is 3tflops

MPE, 8gflops

CPE, 11gflops

the peak computing power of Shenwei Taihu Lake light system reaches 100pflops<

it is necessary to mention here that floating-point computing power refers to the processing power of computer floating-point computing, and the computer has a special floating-point processor FPU for floating-point processing.

home computer 2G Hz, 4G Hz refers to the dominant frequency of the computer, the dominant frequency is 4G Hz, and the floating-point processing power of the computer is about 4gflops. However, the dominant frequency is not equal to floating-point processing power

dominant frequency means the number of computer clock cycles per second. The more processing per second, the more powerful the computer is

the main frequency of CPU does not represent the processing power of CPU and the influence of instruction pipeline on the processing power of CPU

clock cycle is the basic unit of CPU operation, and a floating-point calculation may need several to dozens of clock cycles. So the relationship between the dominant frequency and floating-point processing power is obvious.

3. I54590 is a four core, four thread, three-level cache is 6MB. The i7 4790 is a 4-core 8-thread, 3-level cache of 8MB. CPU is not only determined by the dominant frequency.

4. In brief, bitcoin is the first new internet currency to eat crabs in the 21st century. It is similar to Tencent's q-coin. The price of q-coin is about 1 yuan, while the price of a BTC is about $100. What's the biggest difference between them? Because bitcoin is a constant quantity, with a total of 21 million. It can't be remanufactured, but q-coin is different. As long as Tencent is willing, it can be sold indefinitely! In addition, BTC also has some very important features, which is a P2P based format. The specific data on the Internet shows that BTC is an equal and free currency. As long as the Internet is not prohibited, non P2P currencies will never disappear!! At present, many websites and shops at home and abroad are supporting BTC applications one after another. But it is undeniable that BTC is also a very dangerous currency, and behind the danger is high profits.

5. The CPU of my computer is 3.30ghz, which is about 3.54 billion times per second. It's a common civilian computer. I bought it two years ago. I hope it can be a reference for the subject

6. CPU frequency is actually a camouflage data, the previous Pentium 4 is an example, single core high frequency, energy consumption Tiankeng! Multi core processing is now the king, multi task processing capacity, with graphics card GPU auxiliary, 22nm, 32nm, 45nm process, represents the potential of energy saving and performance. CPU's two-level cache and three-level cache represent the opening ability of high-speed channels. In the case of high computing power and low channel, what level can't be reached? Lga1355 and other architectures represent the foresight of the whole CPU, and the computing power is not frequency visible.... High frequency, can only say that the front-end appearance is good, depends on the number of cores, technology level and two or three level cache to see if it is enough, you did not say a few cores, let alone what model, this is not the standard! There is no answer to this question!

7. No, if multiple programs are running at the same time, the al core 2.2g is better than the single core 4.4g. If it is a single task, the 4.4g single core is certainly better. Now u is developing towards multi task operation. For example, if you watch a movie with 4.4g, it's no problem. If you open a few web pages or games at the same time, the cup will happen, but the al core 2.2g is different.

8. Hello, it's equivalent to the human brain. The CPU is the core of the computer
hope to adopt

9. In theory, the computing power of a computer is only related to the processor. The better the processor, the higher the computing power. The more powerful a computer is, the faster it can deal with problems. For a simple example, suppose I open a small supermarket by myself. After a year, all the costs and losses of my supermarket are recorded in the computer. After a year, I need to count the accounts to see how much money I make in a year and what's wasted. Then the stronger the computer's computing power is, the faster your speed will be. Because after a year, you have too many broken accounts every day, and the computing power of the computer processor is poor. The longer you spend, and even the computer is stuck for several days. This is the most intuitive solution to the problem of computing power. Secondly, according to the current computing power of computers, quantum computers have the strongest computing power. All computers work by "algorithm" to calculate what we need. Ordinary computers work by "binary" calculation, that is, "bit & quot;, People who have studied computer know that a character in a computer is called 8 bytes (8bit). Let's assume that if I need to crack a password, it is assumed that it is 10 digits. Now, the password cracking technology is all based on the password dictionary technology (none of which is used), that is, the computer arranges 10 digits in turn. If the order is right, then the password will be solved. Well, you can calculate that the 10 digit password is nearly 1 billion. How long does it take for the computer to calculate? At this time, the computer's strong computing power will come out. The ordinary computer may take several days, and the quantum computer with the strongest computing power in the world may only take one second. In addition, we need to understand that computer computing power does not represent everything, which is determined by a lot of hardware. Processor, motherboard, memory and many other things together.

10. If the program has been optimized for multi-core, that is to say, the multi-core CPU can also play its advantages. It is recommended to take a look at Lenovo's X6 server (the original IBMX Series), which can host four physical CPUs with strong performance.
