Suspiciously ignored is power consumption. That’s the biggest and most useful metric often ignored because it’s less flashy than speed.

I'm also interested in the security features of this new CPU. Where doesn't it sit compared to Apple and ARM (Qualcomm, Titan)?

Modern processor without memory tagging for example is a little..... dated, given how much the new AIs accelerated the vulnerability discovery in all the apps and system components.

Good question.

I’m sure Apple’s chips could do better in single core if they were willing to push the power envelope way higher too.

Multi-core is easy to beat, just add more cores until you win. There were already chips that beat the M series just by having way more threads/cores.

IMO bot that important practically - SiC batteries, active cooling, bypass charging etc - if one really cares about sustained performance (gaming etc), PRC has phones segments big on mitigating thermal throttling. Exclude benchmark drama, golden samples, retail units still vastly outperform passively cooled phones with "better" silicon on long sessions. Otherwise there aren't many usage case where power consumption matters between that can't be trivially made up by slightly better or larger battery and/or passive cooling.
