- hyperbovine 10y agoIt would definitely be advertised as such.
- magila 10y agoIt is actually quite difficult to beat Intel on power efficiency once you start talking about laptop class CPUs. The combination of Intel's advanced fabrication tech and their highly efficient core family of microarchitectures gives them a significant advantage outside of the ultra-low-power space.
- 5ilv3r 10y agoI don't think that's true. Arm chips just don't clock as high as intels can, and no one* cares about clock speed any more. That ship has sailed. Multiprocess web browsers will drive the sales of massively multicore arms (with tons of ram!), and intel will be sunk.
- magila 10y agoIt's not just about clock speed. While Intel Core CPUs don't scale down to power budgets as low as ARM cores, they are impressively efficient on a perf/watt basis. Smart phones achieve high battery life mostly by being very aggressive about reducing CPU load in software (see iOS killing apps the moment they go into the background). General purpose operating systems don't work like that so there's more reliance on the hardware to keep power draw down.
- Redoubts 10y agothey are impressively efficient on a perf/watt basis Is that true? I thought people were trying out ARM rack servers because of the power efficiency vs perf.
- magila 10y agoThe key word there is "trying". ARM servers have had a tough time gaining traction in no small part because the hoped for power efficiency gains have not been realized.
- flamedoge 10y agosounds like Intel hit a pretty sweet work/watt by increasing work while keeping lid on wattage. ARM delivers battery life by lowering work.
- pertymcpert 10y agoNo that's not how it works at all. ARM has always been power efficiency focused.
- et-al 10y agoNo, but I can imagine how slim Apple would make an ARM-based Macbook.
- ketralnis 10y agoThere are ARM Chromebooks and I don't think they last for days. I'm pretty sure most of the power draw on a laptop is the monitor
- 5ilv3r 10y agoMine goes 8 hours with a mainline kernel. I usually charge it once a week. Apple could/would/should do better.
- jlawer 10y agoI would last 12 hours... but the battery would be half the size.
- rasz_pl 10y agoabout 5 hours, just imagine how thin new macs could get!!1 look at iPhone 6 for clues - Apple replaced 0.1 mm thick piece of metal rf shield with a sticker to make it thinner, that removed metal can was reinforcing pcb and all the bga chips, without it iPhone 6/6+ bends, cracks balls under important ICs and develops touch disease.
