What Are CUDA Cores?

- If you've ever owned an Nvidia graphics card, chances are that card featured CUDA technology, a parallel-processing GPU format suitable for developers and APIs alike. What makes it special? Let's dive deeper.

Mate, we didn't ask you to give us a comparison video on different GPU's, we simply wanted to know what CUDA cores are and what they do, instead im left slightly confused and annoyed. Thanks.

This video completely fails to answer the question that is its title and rapidly devolves into a relative performance discussion.

The whole key behind CUDA is that you can program your GPU to run high process calculations in parallel. This offers a higher performance over the CPU. This can be useful in LIDAR and camera filtering, or other large data calculations.

I commonly watch these without largely understanding most of it because I'm dumb brained. I continue to watch in hopes something might stick somehow.

One caveat with cuda is the thread warp. Each SM can handle many blocks of threads, but there is this issue where there is only one control unit for every 32 cores. This means if there is a branch in the instructions, unless all 32 cores in the warp follow the same execution path, the differing execution branches must be serialized. In other words, decreasing the warp size by adding more control units would contribute greatly to the performance of a gpu even of the number of SMs and cores remained the same.

I really liked that RPM to Hz analogy; Nice

I live your videos, a major factor is that is that you actually use 1080p60. by far for me the best science and technology channel. Proud to be here from your sciencey talks!

[Exodus_Collective]

Ive been following tech youtubers for a while now and i have to say ur videos are much more interesting and i learn more from them keep it up

[elitedata]

just what im looking for - a YT channel with a very intelligent man who is very astute and knowledgeable on the technical aspects of the topics as i am - looking forward to more videos - thanks

[carljenkins]

Content, delivery, and style just keeps getting better. To think, I subscribed when there were less than 25k of us. Triple that now. Awesome.

[chriszarganis]

this guy is perhaps the most sane and objective hardware dude on the tube

[MexMX]

I just searched to know what cuda and tensor cores are, and I found a pretty cool channel. Thanks Greg,

05:44 According to the Nvidia's GTX1080 whitepaper, the GP104 used in the GTX1080 actually has 128 CUDA cores per SM. It's the GP100 (eg. as used in Tesla cards) which has 64 cores per SM.

Gotta say that this channel is quickly becoming one of my favorites, nice work.

[Pastechi]

So Greg. Ever taught of being an University Computer Engineer Teacher? Because the things i learn on your channel i somewhat wish i could learn at my universitity but all they do is hand paperwork and be quiet. The way you explained the cuda cores are exellent. Good Job!

[bryandmgz]

This channel will reach tremendous success if you play your cards right tbh

[anthonyuccello]

GREAT video. First one that covers this clearly IMO. I had a hard time finding info on what these were.

[SmartJock]

You're hilarious man! The vids with you and McLovin I got to see a whole different side of you. You seem easygoing and chill. Always informative and you don't seem arrogant when you help people. Thanks bruh.

[pacsmile]

I liked the piston analogy for the transistor, good job.

[GamingPsychologist]

I love learning with you. Keep up the good work!
