Although you gotta keep in mind that the 12th gen hasn't been out for as long as Zen 3 has and how long does one keep a CPU? Years...
For a long time AMD dominated anything that Intel had, only recently that Intel came back with their hot running 12th gen, that is basically only fully utilized on Windows 11, that is a trainwreck still and most of the world is still on Windows 10.
Let's not forget AM4's amazing roadmap, which many people still has B550 or X470 boards and they can still today buy an 5000 series CPU and be up and running basically. With Intel you'd need a whole new platform essentially.
Hence I disagree with what you said Alien, I still think there are several reasons why to go AMD instead of Intel today.
If you are just gaming there is no reason to go AMD. Fact is Intel are faster at it.
They are also cheaper, providing you avoid DDR5.
The only two CPUs in the desktop space that AMD make that are worth buying now are the 5900x and 5950x. For anything else Intel are faster and cheaper.
Sure, if you have an older board that supports the 5000 series? then maybe it is worth paying more for less of a CPU by going AMD (say a 5600x or 5800x) however, it all depends on the spec list of your board.
It would have worked out cheaper for me to buy a 5900x. Obviously I would not have had to buy a new board. However, the board I had (X570 TUF) was not good enough. I paid £210 for that board, and it had two PCIE slots for NVME. On the flip side I paid £230 for a Z690 board that is superior in absolutely every single way, including the four NVME slots it has and the enormous heatsink. It also has far more USB ports and so on.
If you go back to an older board like X370 or X470? you will see the same problem. You are lucky to get one NVME slot, not more than one.
Which means if you want to run SATA drives? you are OK. In my case though? Not only do I not want to but I don't have anywhere to put them.
These are all of the things I had to consider before I bought anything. And as it turns out? it would have been crazy to spend the money on a 5900X (it was £450) and stick with the board I had because it was lacking. Also remember if you have a X370 or X470 you get no PCIE 4, which could prove critical if you are trying to build a budget rig and buy the only cheap GPU available right now (the 6500XT).
Alderlake is every bit as good as Ryzen. It's better in gaming. Sure, right now Intel can not compete at the top end with cores and threads, but when they shrink again they should solve that issue. Besides, unless you are literally desperate for cores and threads that only leaves two CPUs from AMD even worth considering. The 5900x and 5950x. Which cost far more than Intel's competing equivalent up to those stages.
