Not as much which processor manufacturer is better as it is the physical properties of the computer, such as clock speed, # of processors, video card, amount/type of RAM, storage (HDD vs SDD). Far too many factors to say one processor manufacturer is better than the other.
Personally, I have owned both Android and Intel machines and found that (assuming they are comparable systems) that they are almost identical in features/performance. Pricewise, the Android chipsets are a little more economical.
Historically, many folks think that Intel is a more robust processor, but I have serious doubts about that. Kind of like comparing Burger King to McDonalds. They both do the same thing, just a different way of doing it.
Your best bet would be to select a system and share the specifications here (please don’t include internet links to the manufacturer/seller) to get opinions.
And for gaming it’s more about the other parts of the PC.
1. SSD only now. The time of spinning rust is over.
2. Graphic cards only. What you choose varies with what your monitor is.
3. 16 or 32GB RAM is common. My kids went to 32GB.
As per rproffit’s suggestion about graphics cards.
You want a separate graphics card plugged into the motherboard vs. a graphics card/component integrated into the motherboard for optimal gaming. This frees up a lot of hardware, including system memory shared by other components.
Additionally, when looking at computer storage (SSD for example), many higher end computers have capacity in the lower terabyte range vs the prior gigabyte capacity.
All factors to consider as well as system cost. For a high-end system, expect a minimum cost of $1500 or higher.
