probably Apple’s M4 will regain the crown once the first M4 powered Macs hit the market (I don’t think it is fair to use the M4 on the iPad to compare)
Sure, but there's no reason to believe the M4 would be
slower on the Mac. It will almost certainly be at least equally fast. It might be a little faster due to better thermals, especially on devices with a fan (but even on the Air, it might have a little more endurance than on the iPad Pro).
What's less certain is
how much faster the M4 Pro, Max, Ultra will be, especially given that there is no such thing as an M3 Ultra (and it's increasingly likely there never will be). But if we assume the M4 Pro is configured similarly to the M3 Pro, it'll handily beat the SXE.
On the old x86 side, AMD is keeping the pace thanks to the great Zen micro architectures, but it seems like will be Intel who’s going to lead this space, at least efficiency-wise, judging by what they are achieving with their latest Meteor Lake and upcoming Arrow Lake CPUs, and the very promising Lunar Lake System on a Chip.
I really hope AMD eventually finds a way to improve their efficiency.
As for Intel, that'll be interesting to watch. Meteor Lake performance is a bit of a downgrade compared to Raptor Lake, but I think that was to be expected, as they prioritized getting a new design right over making it fast. It's process/architecture, not optimization. Lunar Lake will tell us what their new design is capable of.
the only reason the SXE "wins" in some benchmarks is because it's got three times as many P cores (and 50% more cores overall). The M3 Pro, still not a proper comparison as it's half E-cores, makes this more obvious.
Yep. It's an interesting choice, too. Qualcomm is no stranger to e-cores; they even do three tiers on some SoCs. So why just one on the SXE, which is heavily marketed towards laptops? (Probably because of the design history: Nuvia started out with a server focus, not a mobile one.)
It'll be interesting so see how that evolves.
