The P16 got 21-hours for video playback and 2-hours for the heavy loads test, which is longer than the M3 Max
Do you realize M3 Max is like 1.5x more powerful chip and even it stomped AMD in Wifi battery runtime. Compare this AMD to something of it's level - M3 Pro chip - and AMD gets completely destroyed.
Last comment I'll make on this as otherwise I will sound like an AMD shill but performance and efficiency are at opposing sides, that said the Wi-Fi test is not running the M3 Pro/Max or AI 9 370HX at full load, that's what the loads test is for. What I said still stands. I will explore your "more powerful" claim, so I'll look at the full load performance and endurance below.
Performance metrics also vary significantly between what, who, where and when a device is tested. Even if you use a site (NanoReview in this comment as it shows No. of samples in the dataset) that uses a large pool of benchmark data to establish a more accurate mean, performance STILL varies greatly on how the benchmark tests are designed like Cinebench(x86-bias) vs Geekbench (Linux + MacOS bias...? or rather Windows sucks). I also hear you about only comparing devices in a similar class, but I merely looked at this review. I'll go the extra step and try verifying your claims:
So M3 Pro = AI 9 370HX: 12-Core = 12-Core both are in 16" creator laptops, similar size and retail price. Using multicore benchmarks to ensure full-load, CinebenchR23 shows an average 14799 vs 24407 in favour of the AMD-chip (65% faster is expected as it's bias to x86). How about Geekbench 6 to avoid x86 platform bias? 14579 vs 15545 in favour of the AMD-chip. (So, 7% faster in what Geekbench consider "real-world" load). How long did they last in their respective loads test here? P16 = 116min vs MBP 16(M3 Pro) = 83min. (M3 Pro 28% less endurance on a 11% bigger battery)
So M3 Max vs AI 9 370HX: 16-core vs 12-core, again both are in 16" creator laptops, similar size but here Apple is almost twice the retail. CinebenchR23 'nT' averages 23507 vs 24407 in favour of AMD by 4% (again not Apples to Apples and rather Apples to Windows as x86-bias). Geekbench 6 nT shows 20930 vs 15545 in favour of Apple by 35%, this is more realistic. Now what are the runtimes where you actually use this 1.35x 'more powerful' advantage? P16 (90WHr) = 116min vs MBP 16 (M3 Max, 99.6Whr) = 71min.
So going back to your 1.5x more powerful claim.. Yes, the M3 Max is 1.35x more powerful but it's also going to last 0.61x the duration of the AI 9 370HX in the P16, even with an 11% battery size advantage. You correctly guessed the M3 Pro has the same performance as the AI 9 370HX but lasts 0.71x the duration under heavy load scenarios. Does that mean the AMD AI 9 370HX is more efficient than any of the Apple M3 variants as a whole?
No, but under heavy loads or just video playback... it's closer than you think.
