I'd love to see Arrow Lake on 20A next year. If not I am going Zen 5. I might do anyway, depending on performance and price.
What worries me about AMD is they don't really have an overall good product. 3D chips are good for gaming, non-3D chips are good for applications. Intel has overall better performance across the board. Might loose slightly in gaming (compared to 78003D) but even 13600K destroys 7800X3D outside of gaming is my point)
I really really hope that AMD will do 3D cache on all cores for 8000 3D chips. Not only one CCD like 7900X3D and 7950X3D and hopefully they can bump up clockspeeds as well.
7800X3D is great for gaming but really not that great outside of gaming, meaning 7700X performance or even less. 7800X3D can beat 7950X3D in some games, showing why you don't want a half solution.
Give me 8950X3D with 3D cache on all 16 cores and I will probably buy that, unless Arrow Lake delivers a big step forward (which it should).
If Intel truly has 20A/18A ready in 1-2 years, then AMD might be in trouble. Ryzen mostly has been a success because AMD had a node advantage (Ryzen 1000 and 2000 series on 12nm GloFo kinda sucked) and AMD is 100% reliant on TSMC to deliver improvements (sadly for AMD, TSMC prioritizes Apple) but without Apples money, TSMC would not be where they are today.
