Does blender need GPU?
In short, No, you do not need an external GPU.
Not to get too technical but except for drawing and viewport stuff amongst some other things, much of Blender’s core functionality relies very little on a fully fledged GPU.
We therefore can’t officially support and guarantee that Blender works fine on those systems..

Does blender Eevee use GPU?
Being an OpenGL engine, Eevee only uses the power of the GPU to render. There are no plans to support CPU (software) rendering as it would be very inefficient. … Eevee will use the graphic card used by the rest of Blender’s UI.
Why is Blender not using GPU?
Why does a scene that renders on the CPU not render on the GPU? ¶ There maybe be multiple causes, but the most common one is that there is not enough memory on your graphics card. Typically, the GPU can only use the amount of memory that is on the GPU (see below for more information).
Can blender use two GPUs?
Using more than one GPU will certainly speed up cycles. In user preferences->system->compute device you can configure which cuda devices to use (or ignore). … The more GPUs, the more tiles being rendered simultaneously, so two GPUs will cut rendering time almost to one half.
How do I know if my GPU is using blender?
If you have properly set up CUDA and selected GPU Compute in the Render Properties panel then Blender should be using your GPU.
Does blender use GPU or CPU?
Blender is able to use your computer’s central processing unit (CPU) or graphics card (GPU)—or both—for rendering. To eliminate render wait times, you might consider investing in multi-core processors and GPUs with a high CUDA core count.
Should I use CPU or GPU for rendering?
A CPU core has a far more instruction sets available to them than a GPU. As a result, a CPU is more flexible in the types of tasks they can perform. CPUs also have higher levels of cache and much higher clockspeeds than a GPU. Therefore, under certain rendering conditions, they may be even quicker.
Is AMD Good for blender?
Best CPUs for Blender – CPU Recommendations AMD Ryzen 9 3900X 12-Core CPU for fast active work performance and good CPU rendering performance. AMD Threadripper 2990WX 32-Core CPU for great CPU rendering performance.
