What is teraflops? Description, value

The main feature of modern video cards is that their performance is measured in teraflops. What is teraflops? This will be presented in the article. You will also learn how this term applies in console circles.

Description of the term

Description of the term




Flops are a certain number of floating point manipulations that occur per second. Initially, such a term was used only in relation to currently outdated electronic computers. It was in the flops that computer performance was measured. But now these functions are distributed among other components of the central or GPU. That's what teraflops are.

In consoles

According to Microsoft experts, their console brainchild of the Xbox One X is the most powerful console with 6.6 teraflops of performance.

Such calculations are performed as follows: you need to take the number of parallel processor cores that the Xbox One 768 has. Then you need to look at the frequency of the graphics core, and the console has 853 megahertz. Now the matter remains small - multiply the first quantity by the second, then multiply by two more and divide by a million. The result is 1.31 teraflops. This is the performance of the Xbox One console.

Teraflops in video cards




What are teraflops in video cards? To begin with, it is worth understanding the meaning itself, since it is not the original one. In one teraflops, a thousand gigaflops, a million megaflops and a trillion flops. That is, the initial value is the flop. But they are outdated, as the technical world does not stand still.

Now you can try to compare video cards from different manufacturers. For example, for the Pascal-based Titan generation, performance is measured at nine teraflops, when their red competitors have this figure of 13. So why is it that Nvidia's video cards are more productive?

For such calculations, there is a special formula:

F × n × 4 × 10−6 = R

How to understand her?

  1. R is the total amount, i.e. flops.
  2. F is the GPU clock speed, but these calculations can also be done with the central processor.
  3. n - this indicator is responsible for the number of CUDA cores in the GPU and conventional cores in the central one. For graphics cards from the manufacturer AMD, this indicator is referred to as GCN.

Next, you need to know the baseline. You can use the GPU-Z or CPU-Z utility for this. There are online calculators that help calculate this performance indicator for any video card, as well as ready-made results on various sites.
