Video ram (VRAM)/ frame buffer GDDR6 DRAM has wider memory bus than regular DRAM. The GPU does graphics pipeline/ rendering pipeline. To turn numerical computer data and turn it into something to display on the screen. Opposed to a CPU, a GPU has hundreds to lightweight cores (or shader cores). Single Instruction Multiple Data paradigm (SIMD): a cluster of cores share a single control unit. One instruction is given to each core which handle the same operation among different sets of data. The GPU has multiple sets of instruction stream. Cache: Level 1: cluster of cores share the memory Level 2: all cores

Thank you for this well made video. Would you consider making a video about the evolution of graphics APIs to further this topic?

[@ComputerScienceLessons]

I will definitely take a look at it. I've been looking into OpenGL and Direct3D. CUDA is also set to become significant in big data mining and AI. :)KD

[@jaysanprogramming6818]

@@ComputerScienceLessons OpenGL is old and has evolved greatly along the years but its main strength was its portability. Tha fact that Apple has deprecated it in favor of its own Metal library is a step backward in my opinion. But the future mainstream "open" library seems to be Vulkan.

I am currently studying linear algebra at university and I always wondered what's a real world purpose for it. Now I know😁

[@ComputerScienceLessons]

I'm working on a new series about quantum computers. At least one of the videos in that series will be about linear algebra; quantum logic gates are based upon it. I have no doubt quantum computing is going to bring about a paradigm shift in human evolution - so linear algebra is definitely worth knowing about. :)KD

[@edumeli02]

@@ComputerScienceLessons Fascinating!!!Hopefully by the time I'll get my computer science degree advancements will be made regarding the world of quantum computing

[@edumeli02]

@math It won't. "Conventional" computing and quantum computing are two separate concepts that have different purposes and different usecases. It wouldn't be practical to have a quantum computer at home as you'd have to cool it down to near 0 kelvin🤣🤣

[@jbot9993]

What does it mean when you say that HDMI is slow at 60 Hz. Am I doing something wrong when connecting my 144 Hz monitor with HDMI or this has nothing to do with the display itself?

[@Wrtvrxgvcf55]

most high frequency gaming monitors are indeed hooked up to DVI or displayport, but its also important what the resolution is; HDMI 2.0 supports 4k up to 60hz (1080p at 120hz (but could go higher)), while HDMI 2.1 supports 10k up to 120hz.

[@ComputerScienceLessons]

You should match the refresh rate of the monitor with a cable that can support it. Frequency mismatch will cause shearing effects. Displayport is the way to go with a gaming monitor :)KD

Is the graphics adapter is always used outside the SOC or it can be integrated inside SOC?

[@ComputerScienceLessons]

Early PC architecture (back in the 80s and 90s) put the graphics controller inside the CPU. These days, it's either integrated into the CPU (common with regular laptops) or, if you want better quality, its done by a discrete graphics adapter. This video and web link may interest you :)KD kzbin.info/www/bejne/lXqbdH-Hlt-io5I www.computer.org/publications/tech-news/chasing-pixels/the-integrated-graphics-controller

[@moonhowler667]

I have a number of issues with this video. First, the video ram is not the framebuffer. It's also where any CBVs, SRVs, textures, vertex buffers and index buffers live. Second, HDMI has supported over 60Hz for literally years. Third, your render pipeline is very wrong. Almost every name is wrong and you missed steps. In fact most of what you have in your "render pipeline" are actually things done within the vertex shader, which is only part of said render pipeline. It doesn't help anyone trying to learn if you give them half baked information you barely took the time to google.

I hope you find what you are looking for elsewhere.
