The number of teraflops (tflops) indicates the number of floating commacks of calculation that a computer can perform in a second. This value is used to measure the power of processors, including graphic processors (GPU) and supercomputers. TFOPS are particularly relevant for applications involving intensive calculations, such as artificial intelligence, scientific simulations and machine learning.
What are the flops and what are they used for?
Flops is the abbreviation of » Floating point operations per second ». It is a unit to measure the computing power of a computer. A floating comma operation is a mathematical calculation using decimal numbers represented in the form of floatunlike integers. This is particularly important for intensive calculation applications which require a high level of precision.
Flops are mainly used in scientific calculations, simulations, artificial intelligence, Machine learning and graphic applications. They play a central role in various fields, such as medical imaging or physical simulations, or in the financial sector for the analysis of market data. In the game industry, they determine the graphic performance of modern GPUs. The increase in the number of flops allows modern computers to calculate increasingly realistic physical effects and High resolution graphics.
Flops are generally measured by reference tests specially designed for this purpose, which determine the number of operations in floating comma per second. Among the different benchmarks used, we can cite Linpack, which is mainly used for superordinators, and the benchmarks FP32/FP64, which evaluate the computing power of the GPUs. These tests consist in carrying out Complex mathematical calculations In order to determine the number of operations per second that a system can manage. Manufacturers often give the theoretical flop values based on architecture, while real applications can vary depending on the workload and efficiency.

How many flops correspond to a teraflops?
A teraflops corresponds exactly to a Billion (1,000,000,000 or 1012) of operations in floating comma per second. This means that a processor or a GPU capable of performing 1 TFOL can make a billion of calculation operations per second.
For comparison, a computer that reaches only one flop per second would take more than 31,000 years to carry out such a large number of calculations. A teraflops is therefore an extremely powerful calculation unit that allows modern real -time applications.
The other flop units and their conversion to tflops
There are different flops units, which vary depending on the computing power of a system. TFOPS conversion is carried out using Powers of ten ::
| Unit | Flops value | Conversion into tflops |
|---|---|---|
| Kiloflops | 103 Flops (1,000) | 10-9 Tflops |
| Megaflops | 106 Flops (1 million) | 10-6 Tflops |
| Gigaflops | 109 Flops (1 billion) | 10-3 Tflops |
| Teraflops | 1012 Flops (1 Billion) | 1 tflop |
| Petaflops | 1015 Flops (1 Billiard) | 103 Tflops |
| Exaflops | 1018 Flops (1 trillion) | 106 Tflops |
Supercalculators are now measured in petaflops, or even in exafops, while high -end graphics cards are often evaluated in teraflops.
How many flops reach modern computers and GPUs?
Modern computers in the field of High Performance Computing (HPC) and graphic processors have now reached impressive flop values. For example, the Nvidia H100, one of the most powerful GPUs for AI and Data Centers applications, reached 989 teraflops for Tensorcore FP32 calculations. This makes it ideal for neural networks and large -scale simulations.
The NVIDIA A30, an optimized GPU for data center, reaches around 10 TFOPS and is particularly suitable for training and inference in artificial intelligence. For comparison, the NVIDIA RTX 4090 graphics card, intended for players, reaches more than 100 TFOPS when it is overclocked, thus offering graphics of striking realism.
The supercalculators are still much more powerful: the “frontier” supercomputer exceeds the bar of 1 exaflops and is used for very complex scientific simulations. Other high -performance supercomputers, such as the Japanese « Fugaku », are used in research and also reach similar powers.
