I've always been an Nvidia graphics card user, and I don't know anything about AMD. I have some questions about switching over. (lemmy.one)

I have the following questions about AMD:

  1. If I want to switch to an AMD GPU, do I need to change my motherboard? Or do all motherboards work with both AMD and Nvidia GPUs?
  2. Do I need to buy an AMD CPU as well? Or can I use my existing Intel CPU with an AMD GPU?
  3. How does the AMD GPU naming convention work? More specifically, what is AMD's equivalent of the RTX 4070? (I want to get a 4070 but I figured it would be a good idea to research AMD's options)

  • For 1, all motherboards should work with both AMD and Nvidia GPU.
  • For 2, you can mix and match, there are some benefits to using both an AMD CPU and GPU, namely Smart Access Memory
  • For 3, AMD's naming is confusing as hell but basically they used to have R3, R5, R9, etc for different tiers of cards, but now everything goes under the "RX" naming prefix.
  • They use the X and XT suffix to differentiate the fastest versions of the same tiers of cards or revisions of cards. (Kind of like Nvidia's TI suffix)
  • The equivalent of a 4070 is a RX 6950 XT as far as I'm aware.

"Smart Access Memory" is just AMD's marketing term for Resizable BAR. You don't need an AMD CPU or GPU to make use of it.

Good to know! Didn't realize at first it was just their marketing term for Resizable BAR lol TIL
