• Things to check:
  • GPU model/producer
    • AMD/Nvidea mainly
• Video card is a bit like mini computer, it has
  • processing unit
  • cooling system
  • memory
  • bus
  • etc…
• Different cards can use similar GPU but with different frequency or memory bus speed
• transistor size - the smaller, the better (less power consumption and heating with the same power)
• No reason to add good GPU if CPU is bad
  • CPU prepares image model
  • GPU shows (renders) it
• RAM size and speed matters. Use GRAM (RAM for graphics)
  • GDDR5
  • GDDR5X
  • GDDR6
  • …
• Bus width and Bus frequency. The higher the better
