Don’t trust any silicon manufacturer’s marketing department. Let the processing and battery life benchmarks and real world tests do the talking.
AMD's CPUs are faster and more power efficient on the same process node. (i.e. 5nm vs 5nm)

Apple just has a big budget to buy out TSMC process nodes a generation early, their designs and architectures aren't actually faster or more power efficient than AMD's x86 cpus.

Am I blind? I don't see any information in there to draw any conclusions about power efficiency. The little information that I do see actually seems to imply the apple silicon chip would be more efficient. Help me out please?
24 threads at 2.00 GHz vs. 8 threads at 0.66 GHz with a 40% difference in TDP. The AMD chip may draw more power, but has much higher performance. Simplifying things, it can perform 9x the operations as the Apple silicon for only 1.4x the power draw.
That... is very naive and inaccurate approach. You can't use frequency and core counts to guesstimate performance even when the chips in question are closely related. They're utterly useless when it's two very different chips that don't even use the same instruction set. But anyway, there are benchmarks in that page and they clearly show that the amd chip is clearly not performing 9x the operations. It is obviously more powerful, though not nearly by that much.
I desperately want something to start competing with apple silicon, believe me, but knowing just how good the apple silicon chips are from first hand experience, forgive me if I am a little bit sceptical about a little writeup that only deals in benchmark results and official specs. I want to read about how it performs in real life scenarios because I also know from experience that benchmark results and official specs alone don't always give an accurate picture of how the thing performs in real life.
That's exactly how you guesstimate CPU performance. It obviously won't be accurate to real life use cases, but you don't necessarily need benchmarks to get a ballpark comparison of raw performance. The standard comparison is FLOPS, floating point operations per second. Yes different architectures have different instruction sets, but they're all relatively similar especially for basic arithmetic. It breaks down with more complex computations, but there's only so many ways to add two numbers together.
Iirc the die area for Apple's chips are also a lot larger and that's expensive. It's a lot easier for them to tank that cost because they are building them for themselves rather than selling them to vendors who manufacture products like AMD.
Yeah, Apple's vertical integration and volume is enviable.
Where you see vertical integration, I see unnecessary and customer antagonistic siloing of function. Do you have any idea how impossible it is to send an apple user money from a non apple device?
What does unnecessary and customer antagonistic siloing of function have to do with Apple's vertical integration of manufacturing process? One doesn't prevent the existence of the other within the same company.
