The computing power of modern computers is measured in flops, a unit for floating bench operations per second. Very powerful systems reach exaflops levels, which means a trillion (1018) operations per second. This immense calculation capacity is crucial for complex calculations.

What are the flops and what are they used for?
The acronym flops means Floating point operations per second And describes the number of floating comma operations that a computer can perform per second. Arithmetic in floating comma is essential for scientific calculations, simulations, artificial intelligence and other gourmet calculation applications. Unlike simple operations with whole numbers, the floating comma numbers allow the representation and calculation of decimal numbers with great precision.
The performance of a computer in flops is measured by specific benchmarks that test how many operations in floating comma can be carried out per second. Programs like Linpack or HPCG are often used, carrying out complex mathematical calculations and measuring the speed of calculation under realistic conditions. Real performance can vary depending on the hardware, software optimization and the type of calculations.
How many flops correspond to an exaflops?
An exaflops is equivalent to exactly 1018 Flopsor a trillion of operations in floating comma per second. As a comparison: a petaflop (1015 Flops) is a thousand times smaller than an exaflops, and a teraflops (1012 Flops) is a million times smaller.
There are different flop units, which are distinguished by the number of operations per second:
| Unit | Flops value | Conversion into exaflops |
|---|---|---|
| Kiloflops | 103 Flops (1,000) | 10-15 Exaflops |
| Megaflops | 106 Flops (1 million) | 10-12 Exaflops |
| Gigaflops | 109 Flops (1 billion) | 10-9 Exaflops |
| Teraflops | 1012 Flops (1 Billion) | 10-6 Exaflops |
| Petaflops | 1015 Flops (1 Billiard) | 10-3 Exaflops |
| Exaflops | 1018 Flops (1 trillion) | 1 exaflops |
These units help better compare the computing power of different systems.
How many flops reach modern computers and GPU?
Modern high performance computers are now reaching exaflops levels. The first exaflops supercomputer is Chinese Tianhe-3 of the National SuperComputter Center in Guangzhou, which provides until 1.7 Exaflops. Other superordinators like the American Frontier also reach levels in exaflops.
High -end graphics cards, used for gaming and machine learning, also reach high flop values, but are still far from the level of exaflops:
- NVIDIA RTX 4090 : approximately 82 Teraflops (0.000082 exaflops) for FP32 calculations, with a slight possible overclocking gain
- NVIDIA H100 SXM : Approximately 989 Teraflops (0.000989 Exaflops) for FP32-Tenseorcore calculations
- NVIDIA A30 : approximately 10.3 Teraflops (0.000010 Exaflops) for FP32 calculations
- AMD Radeon RX 7900 XTX : approximately 61 Teraflops (0.000061 Exaflops) for FP32 calculations
While GPUs are mainly optimized for parallel calculations in AI and graphic processing, superordinators are used for extremely complex simulations in science and industry.
