I've heard that GPU is inside the package of the CPU. That is, CPU has it near itself. Is it true? If yes, what is the GPU with the graphics video card? Might we have two GPUs one with CPU and the other in the video card?  My next question: It's said the the GPU has much bigger speed in calculating/processing the instructions with less power consuming. Once again, if it's so, why don't manufactures produce only GPUs instead of CPUs?

It seems to me that these days lots of calculations are done on the GPU. Obviously graphics are done there, but using CUDA and the like, AI, hashing algorithms (think bitcoins) and others are also done on the GPU. Why can't we just get rid of the CPU and use the GPU on its own? What makes the GPU so much faster than the CPU?

The rendering time on my laptop is starting to become absurd in order to get a decent looking scene. I am looking at building a pc that is well suited for blender. What components are the most important? Most of my projects are rendered using cycles, so a Nvidia graphics card is a must plus lots of ram. But I want some more information, like what cpu (Amd?)? What graphics cards would you recommend? If you have the time could you list a couple different builds such as premium, budget, ect.?  I know that there are other ways of lowering the rendering time (i.e. better poly management), but I have been looking to build my own rig for a while.   Thanks Guys!

Is there any tutorial to install CUDA on Ubuntu 18.04?  The instructions on the Nvidia website for 17.04 and 16.04 do not work for 18.04.  I get a message telling me to reboot then re-run the installer.  However when I do this I get that same message again.

I just started learning about parallel programming course on Udacity and already I am kind of confused. Here at this video segment:    We're told that the average GPU has thousands of ALUs and Hundreds of processors. I am confused by the "hundreds of processors" part. Why are there that many? Shouldn't it be just one...? GPU does stand for graphics processor unit. Isn't a GPU like a CPU, one processor with the thousands of ALUs inside, BUT entirely specialized for certain tasks? How do these "processors" come into play?   If I'm wrong then I assume that each processor has perhaps about 10 (because 10* hundred CPU's = 1000s of ALUs) ALU's inside it? Is there a layout I can see so I can verify this?   Thank you.

I have a new Sony E Series Vaio with an intel i5 and an AMD 7xxx mobile card. Despite making sure sure my app (game) is set to High Performance in switchable gfx and choosing high performance power plan I'm not entirely convinced the gfx card is being used over the CPU's HD4000 chipset. Is there anyway I can prove for sure the AMD card is being used?  thanks for reading  (OS is Win8 64bit)

Today I see that there's an update to my graphics card driver (NVidia GT 220) available on Windows Update. Should I install that, or stick to the drivers provided by the manufacturer?  (Re-asked here after asking on gaming.stackexchange).

I was wondering if there now (as of Blender 2.78c) a way to use GPU rendering on an Intel Iris Pro Graphics Card. I tried to get it to work, and successfully got the GPU to show up in the System User preferences, and in the render tab, but when I try to actually render something, the message at the top says LOADING RENDER KERNELS (MAY TAKE A FEW MINUTES THE FIRST TIME). However, it seems to take more than a few minutes. This message never goes away and I need to force quit blender to stop it. Any way to properly do it?

What are the main differences between each processor generation of Intel processors/chipsets? Is there a performance difference?  I've already seen processors from first to sixth generation, however I don't know/understand the exact differences.

As I can remember, on old systems (Pentium II or III) it was not possible to boot and run the PC if the graphics card was missing (AGP cards were used in those days).    Many years from then, I'm using motherboards with integrated graphics and I have no experience related to this subject, the "graphics card" always was present.  Currently I intend to build a home/private "server" for my purposes and most of the motherboards I want to buy have no integrated graphics (AMD 870 or 970). I can take a normal graphics card from my friends for a few hours/days and use it when installing the necessary software.    Can I boot and run the PC without problems after I install everything I need and the graphics card is removed?  If a general answer cannot be given, at least some examples of manufacturers/MB series/MB models will be helpful.  I think it's obvious, but for completeness, I mean cheap desktop components and not real servers.

I am confused by the difference between "Cores" and "Processors". A lot of the computers are 2-cores, 4-cores. Does this mean that they have one processor with 2 or 4 cores on that single processor?  Also, for intel core i5, it seems that there are 4 CPUs in the task manager, are they referring to 4 core on a processors, or 4 processors with one core each, or 2 cores on 2 processors?

I don't know why, but I cant render anything in CUDA and OptiX but OpenCL work fine. I cant use Cycles render because it's very laggy. I have newest  version of Blender and an RX 590 Red Dragon 8gb. Why does that happen?  How can I turn on my gpu?

I have 14.04.5/16.04 or newer and an AMD GPU. I'm not getting the performance I want, and some programs say they need things like OpenCL.  I've heard about fglrx, but if I try to install it on my machine, it breaks and I have no GUI.  Is there anything I can do to get my AMD card working to its full potential?

I just ordered the Nvidia GTX card. I have a dilemma, though. Should I keep using the driver which is available in "additional drivers" in Ubuntu, or should I install the driver from the Nvidia site?  So which driver is the best for me?

I recently bought a new laptop with following configuration   CPU: Intel i5 2450 RAM: 8 GB DDR3 GPU: NVIDIA GeForce GTX 520 1GB   I've setup a virtual machine using VirtualBox with Windows 7 as guest. I want to use my (host's) graphics card in it but the virtual machine is only showing 128 MB of video memory.  I am using Bumblebee and start the virtual machine using   $ optirun VBoxManage startvm "Windows 7"   Please suggest me how should I use my graphics card for 3D acceleration in virtual machine.

Today, comparing processors is obviously not just looking at the frequency and the number of cores.  When choosing a new PC, how do you compare processors? Is there some resource, like a site or something that does (not necessarily super-precise) processor comparisons?  Thanks.

I am researching on hardware requirements for my new PC. One of my requirements is to have dual monitor display to use while programming. I understand that most integrated graphics cards do not support dual monitors (?), and I will need a standalone graphics card for this. But I also want a quiet PC, and graphics cards can be quite noisy. I am not a gamer, and other than dual monitors, I don't anticipate much need for a dedicated graphics card (though an added boost to UIs would be a nice to have).   What should I look for in a low-end, relatively silent and less power-hungry graphics card for my purpose?  How do I calculate how much memory it should have?  What should I look for in terms of output ports? (I am intending to use two 22 or 21 inch 1080p monitors - an area I need to research into as well).   I will be running Windows 8.1.

This is the third reinstall of Ubuntu 14.04 I have done today.  I just bought a laptop with an Core i3 processor and an Nvidia GeForce GT 840M graphics card.  I have installed the Nvidia driver using their .run file, and also following tutorials, and it just doesn't work. When I check in the terminal which GPU I am using it says "i915" instead of "nvidia".
