You hear these initials all the time: "CPU" and "GPU." They're so common but we don't really talk much about them, so what are they? What do they do? Let Gameranx explain. Subscribe for more: http://youtube.com/gameranxtv

I think this would be interesting also in another perspective: Video Rendering with Software such as Vegas or Premier.

is that Youtube whore (Song created by pewdiepie) piano in the background 02:27
I'm sorry but I couldn't concentrate on the video because of the background music being the same music used in PewDiePie's old 'Youtube Whore' song....

Suggestion for next videos: playing & running triple 'A' PC games in 8Gb RAM vs 32Gb.

CPU also provides raw pre processed frames to GPU which does all the coloring, post processing effects, etc. Another reason why processor needs to be even with a GPU

Still more powerful and better UI than PS4 Pro. But let's imagine that xbox goes away. What stops Sony from overcharging and underperforming, with no competition? It's the uneducated that insist power matters in 2013, but doesn't matter in 2018. Of course nobody understands capitalism, millennials think socialism is the savior for humanity, but don't stop to realize that capitalism gave us the very platforms like affordable ways to watch and comment on YouTube. If xbox goes away, everyone loses. So instead of pushing a fake console war, why don't you let the free market play itself out. Microsoft has all the incentive in the world to make a comeback. OP conveniently left out the part about xbox being more powerful. He acts as if the CPU bottleneck was something that doesn't affect all consoles, and therefore getting an xbox is a waste.

well most modern pc games requires for recommend specs an GTX 1060 6GB video card while they mostly only need an i5 processor does that mean that most games need an stronger video card than an processor?

Everything you see is handled by GPU and everything you cant see is by operated by CPU.
if the cpus keep getting better and they will we don't need gpus anymore

CPU: The one that translate/interpret codes like: Application programming interface, OS, BIOS etc. in a hardware mode. Then sending the information to other PC components like RAM, GPU, HDD and then send it back to CPU. It's like a never ending loop of processes happening inside the system. GPU: A component that is basically build for General Purpose computing (GPGPU) to process number crunching computation - which is more faster than the CPU by miles. A GPU is composed of hundreds/thousands 'Shader Threads/Cores" (Stream Processor or CUDA) to process complicated stressful apps like games's Visual effects, Physics, Tessellation, Anti-Aliasing and even AI.. Something that a CPU can't all handle.

Cpu low level math equations +,-,x,div. reads code using logic to push around memory and do work with it. Gpu very fast floating point equations, like geometry (or decimal point), more memory 4gb-8gb etc allows for larger, more and higher resolution textures, memory speed GDDR4 8000Mhz-10000Mhz, which is very important for fps and kept close to the GPUs processing core, instead of using DDR4 3200Mhz halfway across the board like APUs. I think CPU "Equations per Hertz or second" effects GPU bottlenecking (IPC).

APU for someone who don't update, like a console gamer..... Your right, but Sony and Microsoft sell us their 'update' with a new console for the same generation....

Don't forget about Physx too. The gpu is more capable of the physics in video games.

Spend twice as much on your GPU. So if you had $300 to spend. Spend $100 on your CPU and $200 on your GPU.

If you had $600 to spend, then $200 on your CPU and $400 on your GPU.

What if in future we made quantum computer enough small to use at home and invented programing languages, softwares and even games then how it will be used as a cpu or gpu or apu? Or maybe something different i don't know but i wanna know.
Starman Gaming (8 days ago)
The way you explained it, Falcon, reminded me about the Left and Right hemispheres of the brain, where the left side (CPU) handles logical thinking and reasoning, while the right side (GPU) handles abstract thinking and creative processes. Weirdly, the APU reminded me of how some brains function by using both in a singular process, like some select cases of Autism or Aspergers. So, the whole group of Processing Units are just parts of a Mechanical brain.

CPU excels at Complex calculation with a small amount of data. GPU excels at Simple calculation with a huge amount of data.

Would you say my FX 8350 is bottlenecking my 1060 6g or at least, holding me back from getting better frames in some modern games at 1080p? Witcher 3 Ultra can get to low 50's in forests and FF15 can run in the 40's with everything set to average during intense fights and 50's in car rides.

In the end, Having a good gpu is better with an average cup, than the vice versa. Talking by expirience. You cant go with trash cpu ofc, use reasoning, get an average cpu and a good gpu and youa re done. Period.

David Nikolić (9 days ago)
To be more precise: CPU is optimized for all around tasks and serial operations (SISD) while the GPU is optimized for a specific task and parallel operations (SIMD). Back in the days the cpu did all the work including graphics but as graphics became more computing intensive a seperate processor was designed just for it in order to off-load some of the work from the main processor (graphics related operations were by far the most intensive a cpu had to do). In recent years GPUs have been put to use in applications other than graphics; these were the kind of tasks which required relatively simple but repetitive operationa (for which parallelism was ideal) and thus came the rise of GPGPU. As for Bitcoin mining: yea GPUs would be better at hash calculations than CPUs but bitcoin miners use an ASIC for that (which is waay faster than a GPU for that purpose)

Can a strong CPU paired up with a weak GPU cause negative effects? For example, I will be installing a I5 7500 CPU and it will be paired with my radeon 6870. Please any input would be appreciated as I’m new to the computer gaming scene

Nathan Flannery (9 days ago)
So tired of the 60FPS trope that continues to get pushed. There is nothing wrong with 30 FPS, especially when dropping from 60FPS to 30FPS lets you run at a higher resolution.
Martin (5 days ago)
Nathan Flannery Clearly you're the one trolling here or just being intellectually dishonest comparing watching a video with playing a game. Frame rates impacts perceived input delay. When you're playing a game with low frame rates, the mouse/controller input feels much slower and more sluggish. When watching a video you don't control the game, so input delay doesn't matter. And then there's frame latency. A movie will not fluctuate, digital playback is different to real-time processing.
Nathan Flannery (5 days ago)
You've got the translation wrong. You are an outlier to the standard, because of your vertigo you actually have a reason to call 30FPS a less desirable experience. The point I'm trying to make is that boneheads like Martin here are just trolls, claiming that anything less than maximum is unplayable. So I wonder how they deal with movies/TV/Youtube at 30FPS.
Martin (5 days ago)
Nathan Flannery Less than 144FPS is garbage.
BootLoxes (5 days ago)
But on a serious note, while 30fps isnt unplayable, it does affect the experience. A more fluid experience is overall just better.

Douglas Aranda (9 days ago)
Well, it calculates everything, from positioning in x,y,z, to size, and after that, it still has to render all 3d scenes in a 2d manner where it can be displayed on a monitor, that's why PCs have to have a separated microchip to handle graphics, it would be too time consuming for a CPU
