What is Floating-Point Performance?

Floating-point operations per second, or FLOPS, is a performance metric you see on certain processors, notably GPUs. But what the heck does "floating-point" mean and why is it important?

FUN/GEEKY FACT: The new GPUs with over 90 Terraflops are powerful enough to run Cyberdyne's Skynet from the movie Terminator. In the film at one point they say its 90 Terraflops, which when they wrote the script in 1984, was considered mindblowingly insane! But now, we have that much power in our office/bedroom!

2:55 tfw linus is such a pro at dropping stuff, his mere presence infects other people with this superpower

Do IPC (instructions per clock) as fast as posible guys. We need that episode

I remember the floating point being a dedicated chip on the mother board and in vary early pc kits, they were up-gradable and some were even flash-able like CMOS BIOS chips. That is still the way on mainframes of about 20 + years back are upgraded.

I love my IEEE 754 double precision numbers <3

The Tom Smith that watched this is freaking out by now.

Linus: *exists
Stuff: *drops

He can drop stuff with just his mind.

Literally just was coding something and needed info on this topic. Thanks techquickie for your perfect timing!

What a forced acronym

omg! I am Tom Smith! HE SAID MY NAME! Haha :D Thx Jon for writing us in the script :)

[MrRajabMrwass]

two days ago when I was youtubing for floating point I said to myself I hope Linus make a video about it. And you did :D thank you a lot

@Techquickie
Is this related to the whole teraflops talked about with the PlayStation and Xbox?

[zelmatrix]

This has to be the most simplified explanation of Floating Point per second calculations I have ever seen.

I want to know how to calculate the computation of 1 GFLOPS processor would process 1tb of data?? Is it divide 1terabyte into megabytes then times by 1GFLOPS? I just need to know what 1 GFLOPS can process out of the 1tb data per second. Thanks

Would be nice if there was a single number that could precisely determine performance or maybe just a benchmark that every product had to go through.

[matamanthemaster]

Very good vid. Already knew about IEEE floating point from uni but that was really good info about FLOPS. I'll remember that acronym and look at FLOPS now :)

I'm on my office desk, sipping coffee while watching Linus Videos at my free time until I came to part 2:53.. I spilled my coffee laughing.

[docjazz]

Did this as I was watching and was able to switch the resolution on this video from 1080 to 4K before the video ended thanks for the tip!

[desertfox]

Nice work, Linus! Make more videos like this one, simplifying abstract concepts.
