I have the following questions about AMD:
- 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?
- Do I need to buy an AMD CPU as well? Or can I use my existing Intel CPU with an AMD GPU?
- 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)
Other people are giving good advice, but I’d also add, if you want to compare graphics cards, really check out the GPU benchmark.
Figure out what your budget is, then go with the highest scoring card in your budget range.

The RTX 4070TI scores 31,678, near the top of the high end charts and for $789, it had better!
The Radeon RX 7900 XTX scores SLIGHTLY higher at 31,767, but it’s over $200 more expensive at $999.
So are those 89 extra points of performance worth an extra $220? ($2.47 a point?) No. The performance on both cards is essentially identical.
Looking at the “normal” 4070 (not TI) it scores 27,035 at $599.
The Radeon RX 6950 XT scores almost 2,000 points higher at 28,888, and it’s only $29 more. (1,853 points for $29 = $0.0156 per point).
That’s a no-brainer, PROVIDED a $600 card is in your budget.
Basically if the performance is within the margin of error, go with the cheaper card.
If the price is within the margin of error, go for better performance.
