TERAFLOPS  ▷ What are they, what do they measure and what is their use? ▷ 2020

Do you know the teraflops concept? Have you ever been told about him when advising you to buy a device?

This one, like some others, It serves to refer to the performance that these have. However, they are not used often, it is not something that the user looks at, simply out of ignorance.

To avoid it, today let’s find out what teraflops is, where it comes from and what it is used for.

What are Teraflops and what are they for? (Floating Point Operations per Second) Teraflops What are they, what do they measure and what is their use?

Although of the following, surely Teraflops Whatever concept sounds the most to you, the truth is that this is nothing more than an amplification of the flops, just as there are others such as Gigaflops, Teraflops or Petaflops, which we will see below.

Flops

Let’s start by stating that FLOPS It is an acronym for the Floating Point Operations per Second concept. this is, “floating point operations per second“This refers to performance that a hardware element has.

This is, the number of scientific operations that the device is capable of performing in one second. It is given in scientific numbering, because, in general, we speak of high amounts of it, for which we use a word with a prefix to refer precisely to a greater number of FLOPS.

Thus, we see that this concept is nothing more than a representation of the capacity of the machine. We found that they exist two types of FLOPS:

  • The one of Current FLOPS, which would correspond to the result of performing a measurement of a piece of equipment or a part at a certain time of use.
  • The one of Sustained FLOPS.

This means that, the higher the FLOPS of a device, the higher its performance, something that interests, above all, those who work with them and need it to be maximum.

Even so, This characteristic is usually not enough to be able to dismiss or not a team, as there are other performance factors that must be considered such as ES, cache coherence, interprocessor communication, memory hierarchy.

flop units

Gigaflops or GFLOPS

A gigaflops is a designated unit to speak of 1,000,000,000 –109 or ten billion) flops.

Teraflops or TFLOPS

In this case we would have a measurement in billions of flops since a teraflops equals 1,000,000,000,000 flops (1012) and 1,000 gigaflops. For this reason, it is common to use it in measurements of huge computer systems.

We can say that a graphics card Nvidia GeForce GTX 1080 it offers a throughput of 9 teraflops, which is nine thousand gigaflops.

Petaflops or PFLOPS

The petaflops is the unit to talk about thousand teraflops, one million gigaflops or one billion flops (1015 flops).

An example of an item whose performance is measured in petaflops is the Tianhe-2 supercomputer, which outputs 33 petaflops, that is, 330000000000000000- flops.

Other units of measure flops

The above are the most used units, although we find other even larger ones such as those that include the prefixes “exa-“,”zetta-” Y “yotta-“followed by the root” flops. “These refer to 1018, 1021, and 1024 flops respectively.

On the other hand, we come up with concepts that refer to smaller amounts of flops such as kiloflops or megaflops, which is 103 and 106 flops.

Teraflops and the world of video game consoles

As usual, the concept used in video games is teraflops to refer to the computational power required by hardware to run the software that is running.

To obtain this approach to the performance of a device, the flops of the CPU and the GPU that compose it are added. Some examples are the 1.31 tflops that the XBox One has, the 6 for the XBox One X version, the 1.84 tflops of the PlayStation4, the 500 gflops of the Nintendo Switch or a mid-range computer, which can be around 3.5 tflops.

How do I know how many teraflops my computer or console has?

This information does not appear, as many others do, in the menus of your devices, not even the most spectacular.

The way to know the teraflops of your devices is know the model of its parts and look for this information, either on the website of each manufacturer (or even by asking them directly) or on the website: Gflops.surge.sh where you will find all this information of value totally updated.

We have to say, yes, that the information provided by the brands will generally be that of the GFLOPS in hardware with stock speed, although, the usual thing is that we are left without knowing what is the case with Overlock, that is, when it is forced, yielding.

To get this information you can use this simple formula:
