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!

LORENSSIOK Floating-point ops in CPUs work the same as in GPUs. There may be CPU/GPU differences when it come to _other_ details, but the _representation_ of these numbers and how math is performed with them is the same in both. It's based on the IEEE-754 standard. *EDIT:* It should be noted that the number format described in this video is a _double-precision_ floating point number, which takes 64 bits of space. Graphics pipelines are generally designed to work using _single-precision_ floating point numbers, which only require 32 bits. This is done for performance, since math with 32 bit numbers is faster than on 64 bit numbers.

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.

Floating Lpoint Operations Per Second What a forced acronym

@TheOJDrinker

4 жыл бұрын

It could be FLOating Point operations per Second, or FLOating point operations Per Second, or FLoating point OPerations per Second... or just FLoating point OPerationS. Could FLOPS per second be redundant like so many other acronyms? The world may never know. (So: FLOP-S, FLO-PS, or FL-OP-S) "Forced acronym" is redundant, an acronym is a type of abbreviation (similar to an an "initialism") that you can pronounce, so pretty much all of them are "forced" unless you're lucky enough to have one that's already pronounceable. (Unlikely.)

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

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

CPUs vs. GPUs is the TechQuickie which actually got me subscribed Amazing vid btw

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

@Hobbles_

6 жыл бұрын

Yes and no. In the specific instance of of the XBox One and the PlayStation 4, their GPUs and CPUs have identical architectures (and both are consoles, rather than PCs), and so TFLOPs actually can be used as a rough estimate of how much stronger or slower one is in relation to another. For consoles, unlike PCs, the engines can be made to interface directly with the hardware, rather than through a graphics APIs and drivers. It's not PERFECT still, as optimization still plays a large role in how well a piece of software performs, however, assuming identical levels of optimization, the higher TFLOPs of the PS4 would mean that the PS4 is X% more graphically capable, with some margin for error.

@tomstech4390

^This is partly wrong, xbox and ps4 share architectures (cpus and gpu) but otherwise they are just pc's they have an OS, graphics drivers and API's (xbox literally runs a version of windows 10) and the Gflops shouldnt really be compared...but they kinda can be, the Gflops talks about the stream processor throughput however a difference in render outputs..ROPs can have a big factor if they both werent so screwed in terms of cpu horsepower, one can have literally 3x the graphics flops of another but have the same rops which wil limit the maximum graphics performance even before it gets held back by the really low cpu horsepower (jaguar was designed for low end laptops...like atom) so consoles are pc's and the gflops can only be very loosely compared. and real world performance mightbe very different to what gflops would leads you to expect.

I remember the mid 90s and my PC in 94. It was a little cheaper because it didn't have a floating point unit in the CPU. It was an SX and not a DX. Though back then it was not a big deal. I still think about FPU and Im not sure what has them now or not lol.

You should do a video on Fast Inverse Square Root

For an idea of what to do for a fast as posible: how voice recognition works

significand is also known as the Mantissa (I believe)

floating point is literraly scientific notation in base 2

Crash Course has an amazing video on how computers/processors work as well: kzread.info/dash/bejne/gWmi1c2jisKtn6w.html

Linus looks good when he reads from teleprompter :)

im confused, if one chip can do 10 floating point operations per second and another, regardless of architecture differences etc... can do 8, wouldnt that mean the first chip is faster? Why is architecture relevant in a measure of final output performance like tflops?

Before FLOPS (usually mainframe) computer performance was expressed in MIPS (millions instructions per second)

They really do need to come up with a better naming system for CPUs and GPUs. When they say a Core I eye matey 42xwing or GeForce Padawan 69-12x edition it literally means NOTHING. I find it extremely confusing. They should have a standard benchmark rating in the name so it's easier to judge what it can do without having to read the small print to find the number of cores and so on. I'm old and remember (for example) the Pentium 2 266 MHz, and you immediately knew the speed compared to other processors. They need to say Intel i7 (standard rating) or Ryzen 7 (standard rating), and I think people would find what they are looking for a LOT easier.which would ultimately lead to increased sales. It would also be advantageous in knowing if a game would run on your system by having something similar as a standard benchmark rating for GPUs.

3:11 | i wouldnt say that you can compare the importance of mflops with mp

Anton is a wonderful person. Not a supercomputer.

Gonna wait for the B-Minus Tech Tips Version on this...
