And about a claim of performance leadership for A18:
...except all the phones with snapdragon gen 4 CPUs
There is no single number that can encapsulate the realities of CPU performance. That said, it is well understood that single-thread performance is vastly more important than multi-thread performance for phones. In fact, it's more important in general, in that ST performance will naturally impact MT performance.
Except...
You can get a very high ST score by pushing clocks as hard as possible, but there's a problem with that: power and heat. And it gets much much worse when you try to do that for multiple cores at once. For desktops and some laptop scenarios, heat is more likely to set a practical limit, while in phones, both power and heat can.
Because of all this, the notion that snapdragon g4 chips are superior to the A18 is hilarious. The A18 has superior ST performance, by a *lot* - much more than a quick glance at the GB6 numbers might lead you to believe - because of clock speeds. The two chips are on the same process, but even with its inferior performance, the SDg4 is clocked about 10% higher than the A18, which means it will generate well over 10% more heat (power and heat scale faster than clocks). So it will throttle faster than the A18, and will throttle harder as well, leading to even bigger performance deficits for any sort of sustained load. Of course, most phone loads aren't sustained, but even then the A18 has the advantage in power consumption while maintaining the lead shown in the ST benchmark.
As for MT... What that score means to a phone is not at all clear. Backgrounds tasks are invisible to users, for the most part, so optimizing for power rather than speed is likely to be a win for the user. There are a few foreground tasks that might depend on MT, like some (not most!) games, or video work, but that's an extremely low %age of phone use.
So having a higher MT score is clearly not inherently bad, but you really need to look at the details to see if it's good. SDg4 gets that score with two too-highly-clocked (as explained above) P cores, and six E cores (as opposed to Apple's 4 E cores). As with the P cores, this draws more power than Apple's chip, and thus will throttle faster and harder. The end result is that for background tasks, the difference is meaningless except for Apple's power advantage, while for user-facing tasks, the advantage SDg4 has (from its two extra E cores) will quickly turn into a deficit in any scenario involving sustained use.
Thus the SDg4 will only have a slight MT advantage in scenarios where the user is doing something that requires sustained MT performance for very short periods. What sorts of tasks fit that description? I can't think of any, except for running certain benchmarks! I'm sure such use cases exist- but they're rare.
Bottom line: In virtually all real-world scenarios, the A18Pro is superior. While most people won't notice the performance superiority, it's there. On the other hand, the improvement in power consumption and heat generation (and thus battery life) will be noticeable.
