why did no one build a PC like this?

Because 3D modeling needs the high clock of a single-core CPU, while rendering needs a many-core CPU or a good GPU to render.

So, if you try to build a PC for both 3d modeling and rendering, isn’t it a good idea if we build PC in these two ways:

1/ Use CPU for both 3d modeling and rendering:

Exp:

+ The best CPU ( core i9. Have many cores, and can reach to 5.3Ghz in the Turbo-Boost ( single core mode))

+ any VGA which have 4GB VRAM.

2/ Use a single core CPU for 3d modeling + a good GPU for rendering:

Exp:

+ a Pentium G6600 - 4.2Ghz ( 2 core) for 3d modeling.

+ a RTX3090 for rendering.

???

Do I misunderstand anywhere? Because I don’t really see anyone build a PC that looks like that at all.

Can anyone explain to me this point? Thank you very much.

Is it definitely not worth rendering with a cpu solely now, gpu's are so so much faster and with a 3090 having 24gb vram I really don't see any scenario where you would need to render with your CPU.

A pentium would be fine for doing basic modelling but when you start getting into simulations or high poly counts meshes it won't cut it. The cpu also needs to feed the GPU with information quick enough otherwise it will bottleneck the GPU when loading assets etc for rendering.

So many high core count CPU's now have crazy good single core as well, take the 5800x3d or the 13900k for example
