Chinese-English Translation:

Teraflop即Teraflops（简称TFLOP）用于测量CPU的浮点单元FPU计算性能。含义为每秒执行的浮点指令个数， 浮点运算次数/秒，是衡量计算机性能的一个重要单位。

Teraflop (tflops) is used to measure the performance of floating-point unit FPU of CPU. It means the number of floating-point instructions executed per second, and the number of floating-point operations per second. It is an important unit to measure the performance of a computer.

Teraflop 即 Teraflops（简称 TFLOP）用于测量 CPU 的浮点单元（FPU）计算性能。teraflop 等于 1000 gigaflops，或者 1 万亿 FLOPS，这意味着每秒 1 万亿浮点运算。

Teraflop (tflops) is used to measure the CPU’s floating point unit (FPU) computing performance. Teraflop equals 1000 gigaflops, or 1 trillion flops, which means 1 trillion floating-point operations per second.

It means the number of floating-point instructions executed per second, and the number of floating-point operations per second. Teraflop is an important unit to measure the performance of a computer. It can be expressed as: 1. 1 trillion floating-point operations per second; 2. Floating-point operations of 12 powers of 10 per second; 3. Floating-point operations of 40 powers of 2 per second.

What is tflop?

Terahertz (TFP) is a direct measurement of the performance of the processor’s lOGHz clock.

Specifically, teraflop refers to the processor’s ability to compute 1 trillion floating-point operations per second. For example, to say something has “6 tflops” means that its processor setting can handle an average of 6 trillion floating-point operations per second.

Microsoft rated its Xbox family x custom processor at 12 tflops, which means that the host can perform 12 trillion floating-point operations per second. In contrast, Apple’s 16 inch MacBook Pro has a GPU of up to 4 trillion operations per second, while the redesigned Mac Pro has up to 56 trillion operations per second.

TFLOPs 对游戏有影响吗?

Does tflops affect the game?

Microsoft recently revealed the details of its Xbox family x, claiming that its graphics processor can achieve 12 trillion floating-point operations. Twice as many as 6 trillion floating-point operations on the Xbox one X! The company calls it “a real leap forward in processing and graphics.”. Processor speed is not all about game performance (for example, look at Playstation 5’s performance in storage innovation). Nevertheless, it is still a central factor in determining how well the game is played and how much graphics and motion calculations can be performed at any given time.

All the added energy will enable higher frame rate and resolution support, as well as hardware accelerated ray tracing. This performance will further enhance the variable rate shadows (VRS) of the custom algorithm implemented by Microsoft, which presents a scene in different details according to the location of the focus. This helps maximize performance where it’s most needed, making the game look great without having to use all the resources of the system.

What is floating point operation?

Floating point operation is a common method to measure the computing power of a computer. In fact, once we started using flops, it soon became the international standard for discussing computer capabilities.

Floating point numbers, or “real numbers,” are the set of all numbers, including integers, numbers with decimal points, irrational numbers (such as PI), and so on. From a computational point of view, floating-point computing is any finite computation that uses floating-point numbers, especially decimals. This is much more useful than looking at fixed-point calculations (using only whole integers), because the work done by computers usually involves finite floating-point numbers and all the complexity of the real world.

FLOPS 衡量的是一个处理器在一秒钟内能解决多少个涉及浮点数的方程。在各种设备需要的失败中有很多差异。例如，传统计算器的所有操作可能只需要大约 10 次失败。所以，当我们开始谈论兆次浮点运算(一百万个浮点运算)、千兆次浮点运算(十亿)和万亿次浮点运算(一万亿)时，你就可以开始了解我们所说的运算能力了。

Flops measures how many floating-point equations a processor can solve in a second. There are many differences in the failures required by various devices. For example, all operations on a traditional calculator may fail only about 10 times. So when we start talking about trillion floating-point operations (one million floating-point operations), Giga floating-point operations (one billion), and one trillion floating-point operations (one trillion), you can begin to understand what we mean by computing power.

Manufacturers often use failure as the specification of computers to show how fast they are. However, if you have a custom machine and really want to show off its trillions of floating-point operations.

So, more tflops means faster devices and better graphics?

Although this assumption is true in some cases, it is not uncommon to see GPUs with higher trillions of floating-point operations show lower performance. Strange as it may seem, this phenomenon is very similar to the number of Watts we see. Your final performance depends on many factors.

Take the spotlight, for example. In addition to power consumption, your performance depends on factors such as brightness and structure. These additional factors can make a spotlight look different than a spotlight with the same power. Trillions of floating-point operations follow the same rules – you need to think about core speed, frame buffers, and processors.

However, as a guideline, more tflops should mean faster devices and better graphics. This is an impressive sign of growth. Just a few years ago, consumer devices didn’t even reach tflops. Now, we can talk about devices six to eleven times. In the world of supercomputers, this is even more impressive.

Researchers are talking about supercomputers with more than 10 billion floating-point operations, and 10 billion floating-point operations are 100 billion floating-point operations. At present, the performance record is maintained by a supercomputer built by IBM at Oak Ridge National Laboratory, which has a computing power of 200 gigabits per second.
