GPU selection: NVIDIA vs AMD

Hi! I’m trying to select a GPU from the list to work in EmberGen:
• RTX 4070ti super
• RTX 4080 super
• RX 7800 xt
• RX 7900 xt
• RX 7900 xtx
Which GPU will give me the best performance?
What spec of GPU is essential for best EmbeGen performance (NVIDIA and AMD)?
How big is the difference between NVIDIA vs AMD GPU performance?

Hey sorry for the delay! Personally NVIDIA cards have less problems than AMD typically, and whatever card has the most VRAM will give you the most mileage in EmberGen.

Hope this helps!
