Help me understand Noise node vs. Imported Noise Texture

Understanding procedural materials vs. materials with textures.

If I need a “Perlin noise” effect in a material, what is most performant, to generate a Perlin noise in Engine (77 instructions per level, 4 texture look ups) Or importing a Perlin texture?

When the noise node is plugged-in as Base color, what is the resolution of the noise? Is it 4k, 8k? or is it adjusted on the fly in WorldSpace?

Thanks for clarifying.

I can’t tell you what resolution the procedural noise is, but a texture a very definitely more performant than the noise node. Just because there’s no computation involved.
