Why are we still using CPUs instead of GPUs?

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…

Why do people use GPUs for high-performance computation instead of a more specialized chip?

From my understanding, people began using GPUs for general computing because they are an extra source of computing power. And though they are not a fast as a CPU for each operation, they have many cores, so they can be better adapted for parallel…

How does the CPU and GPU interact in displaying computer graphics?

Here you can see a screenshot of a small C++ program called Triangle.exe with a rotating triangle based on the OpenGL API. Admittedly a very basic example but I think it's applicable to other graphic cards operations. I was just curious and wanted…

Is it safe to keep the GPU on 100% utilization for a very long time?

I am currently performing number-crunching using CUDA on my GPU, an NVIDIA GeForce GTX 1050 Ti. These operations often take months to complete, and during that time I leave my PC on 24/7. Is doing so safe? Am I risking a potential overheating of my…

How can I test my GPU memory/RAM?

I run MemTest86 a lot at work on customer's machines, and it's great for troubleshooting memory issues. My question is, how can I test that a GPU is starting to go? I know of programs like 3DMark to push the graphics card to its limits, but what…

Must a CPU have a GPU if the motherboard provides a display port (when there isn't any separate video card)?

There is such a configuration: MSI A320M PRO-M2 V2 + AMD Ryzen 5 1400 BOX and there isn't any separate video card. When the PC is switched on, the monitor shows nothing. The MSI tech support said: There is no GPU in the CPU Ryzen 5 1400, and the…

Can the GPU use the main computer RAM (as an extension)?

I have a laptop with a dedicated GPU, Nvidia Quadro P3200. It has 6 GB of RAM. The laptop also has 32 GB of “normal” (CPU?) RAM. I’m planning on using the GPU for parallel computing, running physics simulations. Some of these involve quite big…

Why do workstation graphics cards cost far more than equivalent consumer graphics cards?

An Nvidia GeForce GTX 780 Ti costs $700, while a Quadro K6000 costs $4000—yet they use the same underlying GK110 core! The same can be said for other workstation GPUs from both Nvidia and AMD. What exactly does this price difference pay for with a…

How does the CPU communicate with the GPU before drivers are loaded?

As I understand it, GPUs have their own instruction sets, whose instructions are generated by the graphics drivers. The GPU instructions are then sent to the GPU. So, how does graphics communication work before the drivers are loaded? Are there some…

I see rainbow effect on the borders of objects and text, adjusting ClearType or driver reinstall doesn't resolve the issue

I am using a QN90A Samsung TV as my display with an HDMI 2.1 cable. The effect is the most noticeable on Intel integrated graphics (12700K), but also a bit on Nvidia GPU (3070ti). Image of the error with Intel integrated GPU:

GPU struggles only in the primary PCIe slot. Is this a motherboard issue?

When my GPU is in the primary PCIe slot, I sometimes get loads of garbled sound when I run the audio through the HDMI. The GPU also performs far worse on benchmarks. In the primary slot I get 30 fps on Novabench, in the secondary slot I get…

What's the difference between GPU Memory bandwidth and speed?

I was looking at Nvidia's series 10 graphics cards' specs and noticed they have memory speed and memory bandwidth specified. Memory speed is expressed in Gbps and memory bandwidth is expressed in GB/sec. To me, that looks like memory speed divided…
