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?

You can definitely get fairly accurate power draw readings from these chips in macOS, even with Apple’s own debugging tools. If anything, it’s harder (or at least more confusing) to get accurate readings for AMD chips (TDP != power draw).

Also, the TDP the manufacturer states in the spec sheet pretty much doesn’t mean anything these days. These chips will be allowed to draw different amounts of power for different durations under different conditions. This is especially true for the AMD parts, as they run in a lot of different laptops with different power and cooling capabilities. But even for Apple’s M chips there are different configurations: a MacBook Air only has passive cooling while the same chip in a MacBook Pro can have active cooling, which will impact maximum allowed (sustained) power draw and with that, performance.

You also link to CPU Monkey, a website I wouldn’t use for anything but very rough estimates, because their seemingly random collection of benchmarks are likely just taken/stolen from somewhere else (I doubt they benchmarked every single CPU they list themselves) and it’s unclear with what power limits and thermal constraints these benchmarks were run.

Even with all the data, it’s still hard to make a 100 % accurate comparison. For example, the efficiency curves of these CPUs is likely quite a bit different. The M3 might achieve its highest performance/watt at 12 watts, while the Ryzen’s best performance/watt might be at 15 watts (these numbers are just an example). So, do you compare at 12 or 15 watts then?

And yes, there absolutely can be situations where the AMD CPU draws 50% or even 100% (or more) more power under load, and depending on the configuration of the chip in a specific system, the opposite can be the case as well. This in itself doesn’t tell you much about potential power efficiency though.

EDIT: Also, comparing the Ryzen 9 part with 12 cores to the smallest M2 doesn’t make any sense. You’d much more likely compare it to the M2 Max which has 12 cores as well (and again, trying to match the TDP in the spec sheet doesn’t make any sense, as especially for AMD, TDP isn’t even close to actual power draw under load - PPT is at least a somewhat better number here).

I also get that you’re trying to match the process node as closely as possible and TSMC N4 is “just” an improed variant of TSMC N5P, but it still differs. Also, the M2 was released two years earlier than AMD’s AI 300 series, so you ignore two years of architecture improvements which happen regardless of the process node, just look at the (supposed) performance and efficiency improvements from desktop Zen 4 to Zen 5 on the same.

Maybe the new AMD chips are better in many ways even compared to more recent Apple chips, but the comparison you are trying to make is so deeply flawed on so many levels that it’s completely useless and it doesn’t prove anything whatsoever.

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.

Everything I see says the M2 family is 5. Vanilla, pro, max, and ultra.
