Are there any advantages to using cpu and gpu from amd?

Question

Iron

Or can you safely take a percentage of the reds and vidyuhi from the greens?

Answer 1

There are no AMD+nvidia compatibility issues.
And from the fact that you have AMD + AMD, rx will not become more powerful.

Answer 2

With processors, not everything is so simple now, before alder lake one could say "AMD is better in terms of price-performance ratio", now you have to think. According to the video - the green ones have fewer problems with firewood / compatibility than the red ones, the main problem for everyone is availability and prices.
Without specifying the tasks and budget, the question does not make much sense. If you are talking about some synergy of kits (AMD + AMD) vs (Intel + Nvidia), it is not.
