Well there are so many things other than computing world where they are used. Actually they are used in every field at the higher level. Yes every possible field.
we need more of these type of videos on how gary explains how all different parts of a smartphone works together for us to be able to game, mail, fb ,whatsapp, etc
Vertexes??? Come on Gary! I spend half of each year teaching my students that the plural for vertex is vertices. This video is great and I want to use it in my teaching but you're killing me with this vertexes business!!!
+Miller Kavanagh The only thing worse than someone telling you you're wrong is them supporting their argument with an authoritative source. Well, on the plus side I can now get my students to use the video :)
grammar it's not an exact science, in order to know the real truth you should ask the person who invented this word. There might be no logical conclusion otherwise
Rasterisation I think. (Disclaimer: I'm no expert!!!!! Could all be wrong!) Not sure if rasterisation is the right word though. But this is what happens. Basically rasterisation is turning the 3d scene into a 2d picture. Very very roughly and basically what happens is it looks at the scene it has created in its memory and takes a picture of it through a virtual camera - which is the screen - then it is sent to the screen. That's all after the GPU has created the 3d scene in its memory. Which it does by creating the polygons/triangles in the memory and then repeatedly editing the memory to add things like textures, lighting, particle effects, reflections/shadows etc. Then the next scene is made by editing the previous one - transforming, re-scaling, rotating etc the verticies like he says in the video - then calculating the lighting and shadows etc again. All that is why the amount of memory and *especially* the speed of the memory matters a lot. When each frame is complete, it is rasterised (or whatever the word is) like I tried to describe above. A "picture" is taken from the viewpoint of the screen, various processing is applied to make it look better and more natural (like AA/anti-aliasing) and it is sent to the output - the screen.
What an amazing video! I'm a postgraduate in Computer Science and I had done this in Computational Graphics but you just cleared my concepts amazingly Gary. You rock.
Just got hammered because, in my video covering shaders (a really dumbed down version), I say that the pixel/fragment shader runs once for each pixel (I was trying to keep it simple). Now seeing this video, I feel better as you did exactly the same :) I guess great minds think alike :) Nice video!
uh... i am quite new in this era but can a good processor ensure us great performance and can i make games and make my videos much better is gpu required for vr gear
Wow this is awesome. Recently I got interested in building my own PC. So naturally I got interested in what each individual part does. It's really fascinating how they all work to create an artificial world. Really good explanation, even though I didn't understand everything 100%
Each face isn't necessarily a triangle of vertices. Triangles are used to reduce the vertex count but quads offers much better deformation for animation.
how does the GPU get instruction. is it hex code that goes or is it zero and 1's like binary code. i mean would it be posibelt to take a nvidia graphics card to make it calculate something just by letting it get commands from a IC chip
First of all congrats on 2m sub And my question is that what is Xposed And what are custom rom and why are the better than the stock Please explain in the next vedio
I'm still confuse about the parallel thing in GPU. I have read a journal saying that sphere and cylinder have high computational parallelism. How will you know if a figure is parallel enough for GPU?
I love shaders in OpenGL. They are such a powerful tool that are often neglected for some tasks where they just blow away anything that can be done on CPU. Image processing, etc. For example I tried making a 3D scanning app on Android. In Java it was too slow to be practical. In C++ it was somwhat ok but still only 1 frame per second to build a 3D point cloud. Moving pretty much the same code from C++ to GLSL shaders results in an insane speedup sometimes, without much change required since GLSL is so close to C, it is almost just copy and paste. In one instance, the same code that was 19 seconds per frame on a powerful Desktop CPU runs at 30+FPS on a mobile GPU. Just cuts through those calculations like it is nothing. I've been fascinated ever since on what can be done with shaders.
Gary is the reason why I am still a AA subscriber. Gary and Jayce, the rest of the team are pretty much good video makers with a clear lack of enough knowldege to be hosting a tech channel. But then again, most of the most subscribed youtube tech channels are like this: good video making, almost zero quality content.
Thanks for the video and all but I'm tech fried. Will this external GPU will render my video? I have video pad editor (basically like Sony Vegas but I think better hehe) the program basically saying it's too much stuff going on for it to be rendered in real time. I really need to know if this helps with that :)
FIrst off all, the plural of vertex is vertices. Second, the Protostar demo was made in Unreal, not Unity.. And last but not least, this video does not explain how GPUs work at all. It scratches the tip of the iceberg but all of the information is so high level, and more about the software than the actual hardware, that no one watching this video would have the slightest grasp about how GPUs actually work.
Hi Gary, Great video as always. can you please clarify my doubt, once android N is released to older devices running multiple cores, will the graphics performance improve on supported games and benchmarks?
No, not at the moment... however there is no technical reason why it shouldn't, it just a case of drivers. But most OEMs will be looking to add Vulkan support to new devices not older ones.
I finally understand the purpose of learning Vector and Matrix in Maths at school Lol

in spanish is vertices if it makes you feel better ....

@@mrwho2513 probably the best comment I've ever found on youtube!
Excellent video Gary. A good break from the other product reviews. Hope to see more of such videos!
Great video Gary thx for your deep explaining!
Thank you Gary Sims, I understand, what CPU is, What I discovered is that it's using different ways of using graphics and colors, of games etc.
Congratulations on 2mil subs guys!
3M now.
how does the gpu output images to the display?
Still a mystery

RedButtonProductions The 3d scene is mapped to a 2d scene using transformation matrices, then is rasterized and sent to the monitor.
@@DaFinkingOrk wow this is what i came for thanks
the intonation of gary's voice is .......I am heading over to the written article.Thanks a lot for breaking it down to lay people.
What an amazing video! I'm a postgraduate in Computer Science and I had done this in Computational Graphics but you just cleared my concepts amazingly Gary. You rock.
This was a well put together video. Love your channel. Wish there was a similar channel based on iOS
Great video guys !
Congratulations on 2.000.000 Subscribers! :D
awesome video Gary!!
What does "force GPU rendering" do in the developer options
Gary is making me smarter with his video's. good video again.
You have made it MORE complicated for some people sir.,

just liked and subscribed. wish i could do more. i really appreciate the explanation. these are just the details i needed. thank you
thanks for the video...can u plz make a video on how one can create their own android custom rom...plz..
This is a professional and informative video that gives broad insight into the topic in a very short time. Thank you for great content.
definitely would like this series and thanks a lot!
Thanks Garry for providing us with the precious information.
I love your videos. always a thumbs up!
your explanation is the best
love it

Gary definitely has those amazing explainatory skills! I'd love to see more such type of videos
uh... i am quite new in this era
but can a good processor ensure us great performance
and can i make games and make my videos much better
is gpu required for vr gear
As always, very informative
How about the Nvidia Tegra X1?
I was litterally just thinking about this the other day. So glad Gary uploaded it :)

i wish i had a teacher like Gary Sims..... your explanations are so understandable... and also i dog the accent.
Wow, this episode looks like a Techy thingy online class, love it so much ;) Thanks for the deep explanation btw
Each face isn't necessarily a triangle of vertices. Triangles are used to reduce the vertex count but quads offers much better deformation for animation.
Thanks Gary!
Great explanation !!
Great explanation, thanks a lot :D
mannn I did a paper on this almost a month ago. Wish you guys did this video sooner 😭
My GPU is bad in maths. He is of my type. #mygpuislikeme

First of all congrats on 2m sub
And my question is that what is Xposed
And what are custom rom and why are the better than the stock
Please explain in the next vedio
Gary always rocks :)
Wait wait wait, you're telling me it's *not* a home for a kindly elf who eats polygons???
congrats on 2 million subs.
Hi Gary , I have only one problem that you never reviewed a Micormax smartphone? why ???????????
thanks Gary for explaining this 😁
Congratulations on 2 million guys
thanks a lot. a very good explaination
Thank you Gary, finally someone explained me that, seriously I always wanted to know :)
I'm still confuse about the parallel thing in GPU. I have read a journal saying that sphere and cylinder have high computational parallelism. How will you know if a figure is parallel enough for GPU?
"Parallel" just means a problem can be split up into multiple chunks easily. Graphics in general can be paralellized very easily.
I love shaders in OpenGL. They are such a powerful tool that are often neglected for some tasks where they just blow away anything that can be done on CPU. Image processing, etc. For example I tried making a 3D scanning app on Android. In Java it was too slow to be practical.

Thnx for The information
So my math teacher couldn't explain why we need geometry but you did, what a world we live in
Gary videos >>>
Thanks a lot sir.This video is so helpful
love your videos Gary.
which s7 did you mean sn820?

So wait, the Vulcan thing, what is it? I'm aware of it being an improvement but I didn't really understand if it was hardware or software?
Software, like OpenGL or DirectX.
+Gary Sims Thanks!
Thank you AA for making videos like these.....definitly very helpful!!!!!
Do keep making more of these!!!
Gary is the Wendell of Android Authority!
but gary u said CPU do have somthing called ILP... So how its not parallel?
Great stuff Gary
Which game is he showing at 6:46? Nice vid BTW!
Nvm, dumb question, found it in the video
Is there a CPU video like this?
believe me garry i have learned mostly from you Thanks keep doing it
Why are u wearing 2 watches :X just curious
One is a fitness tracker, the other is a watch lol
Joseph Hindy oh lol i see, thank youuu
great video #GARY please do indepth cpu & gpu
Great vid
Is there an english version?
+Gary Sims: can you please explain alu number vs GFLOPS? please
nice background... must be a GS fan

Im more interesed about how gpu use this values to make a picture (comunication to monitor)
Heard of window manager?
It a software program that give every graphics app its own window.
tq Gary for the explanation, appreciate it! keep it up
Can you also make "a what is a CPU" video?
after watching 3 times i understood;thx
thumbs up #gary, please do indepth cpu & gpu video. (fully explained)
This video cured my insomnia.
Thanks a lot..... I a big fan and watched each and every video of this series...... Thanks.
I love Gary videos
Hi Gary, Great video as always. can you please clarify my doubt, once android N is released to older devices running multiple cores, will the graphics performance improve on supported games and benchmarks?
yes it will, vulcan api will help
wich is better nexus 6p or Xperia z5 premium?
Nexus 6P
nicely explained
So I guess the best Android smartphones of the year to play games will be the Samsung GS7 and especially the Note 6(with 6G ram).
Go Vulcan go!
His name is "Gary Sims From Android Authority"!
Gary is the best, I would've loved to see more videos from him!
what happens if I enable msaa 4x.
What about VRam?
Does mali t760 support vulcan api?
No, not at the moment... however there is no technical reason why it shouldn't, it just a case of drivers. But most OEMs will be looking to add Vulkan support to new devices not older ones.
+Gary Sims You are the man , Gary.....
Great video! Very complete!
btw, at 9:15 , that's Unreal Engine, if i'm right.
Thanks for the helpfull Video
