I want to learn 3D design, but does sketchup use a lot of memory and graphics cards? Do you have any computer configuration recommendations?

The sketchup software is not very memory and graphics card intensive. But if you want to learn 3D design, it is not enough to just learn Sketchup. You must at least learn software such as 3dsmax, Vray, Corona, and Maya. This type of 3D software still has requirements for computer configuration. You can refer to the following:

Graphics card: 4G or 6G or above independent graphics card, and the graphics chip should be the latest or second generation.

CPU: 4 cores or 6 cores or above, main frequency is 2.4GHZ or 3.0GHZ or above.

Memory: 16G or above. It is best to choose dual-channel memory or high-frequency memory if possible.

Solid state drive: 512G or above, because 3D software takes up more computer memory.

Screen: Try to choose one with high color gamut and high resolution, such as 100% SRGB.

Heat dissipation: Try to choose a device with a large number of heat pipes and air outlets, because the computer generates a lot of heat during rendering.
