Explain how the graphics integrated into the processor work?

Question

Video cards

Greetings.
There is a core i9-10900K processor with integrated uhd 630 video . I read online about embedded video in processors, but I didn’t really understand many of the features of the work:

• How much RAM can go to video?
  
• Is RAM allocated automatically / dynamically or is a certain amount set in the settings?
  
• With what approximate built-in (separate module) video card can the uhd 630 be compared in terms of performance?
  

Answer 1

1. Specified in the specification of the processor on the manufacturer's website.
2. This is usually set in the BIOS. Minimal amount. Then the system decides. So it's dynamic.
3. Something like this.
Uhd - 1550 parrots
Nvidia 1050 - 5500 parrots.
Then guess yourself
