In a desktop environment you do not want to be thermally throttling. If you are that means your cooling solution is not good enough for your usage. Not to mention that having your CPU hit the thermal ceiling all the time can lead to premature aging/death of the CPU.
Arrow Lake isn't coming out until end of 2024/beginning of 2025 at the earliest. That said even if Intel's node is superior that doesn't mean anything. Intel still cannot get their power draw under control on their P cores. Do you really think Intel would have gone to a BIG.little design if they could have gotten 16 P cores to clock at a decent level all while using lower power? Of course not they would have stayed with nothing but P cores. However, they knew how much power their P cores used and needed to reign in the absolute power requirements so the went hybrid. AMD on the other hand has been able to put 16 big cores all on the same die while keeping power under control. This is because Zen is more efficient that Core. We see this in benchmarks that limit the power (which I referenced earlier). Intel needs double the power draw to equal AMDs performance.
Again Intel needed to throw power limits out the window in able to beat Zen 4. As I had said earlier Core does scale better with additional power than Zen. Once Zen got to 105W the scaling beyond that was minimal. Core on the other hand kept scaling pretty well all the way up to 253W. While that isn't a big deal on the desktop, that can be an issue in laptops. The Intel laptops need more power to keep up with Zen but that has the other problem of reducing battery life. Since Zen 2 was released, on similarily configured laptops AMD has had the battery life advantage over Intel. We also knew that Zen 4 3D was going to be released long before Zen 4 was released. AMD released roadmaps with Zen 4 3D on them over a year ago. One other thing don't forget that Intel made the 13900KS in an attempt to beat Zen4 3D in gaming.
Client computing isn't where companies like Intel and AMD make most of their money. Most of their money is made on data center products. Intel not doing well in data center products is a big reason why they posted a net loss of more than $600M in Q4 2022. Intel needs to strengthen their data center products to make the company financially stable. They cannot rely on client computing to make a profit. Without profits they cannot afford the R&D on new process nodes or CPU designs. Right now Intel is at least 2-3 years behind AMD in the data center market. If AMD keeps executing like they have, Intel will stay 2-3 years behind.
I want Intel to do well same as I want AMD to do well. Competition is the market is the best thing for everyone. It leads to innovation, lower prices, and better performance. The fact that you seem to want AMD to fail outright is a scary thought. Had Zen 1 not been a success, they bet the entire company on the Zen line and it was a bet that paid off, AMD would probably have gone bankrupt. Had that happened do you really think the i3's would be 4c/8t and the i7's 8c/16t? Of course not. We would have been stuck with i7's still being 4c/8t, maybe 6c/12t with little need to Intel to innovate beyond Skylake.
When, Nvidia jumped from Ampere to Lovelace they went from Samsung N8 straight to TSMC N4X! Thats a 1.5 node jump (pretty close to 2 if you ask me). And they managed to more than double performance. Same applied to 20A. With Arrow Lake they're taking a massive jump from 4 to 2. Thats a massive1.5 node jump like Nvidia. It ain't trivial.
