Power consumption is important in mobile regardless of idle or full load. That’s why MacBooks are better than non MacBooks. Even under load they outperform traditional laptops for performance per watt
- fsh 3y agoNot really. A M2 Pro draws something like 40W under all-core load which is comparable to AMD Ryzen mobile CPUs with similar performance. The long battery life of the MBP is almost entirely due to the crazy low idle consumption of the entire system (not only the CPU).
- throwaway2990 3y agoAnd yet, I can’t take any windows laptop I’ve ever owned to work without a charger and work all day and come home. But can do that with the M2 MacBook. Cos under full load, the performance and battery life exceeds that of windows laptops.
- fsh 3y agoThat's because the MacBook idles well, and most of the time is spent idling. Some modern Windows machines like the T14s Gen2 AMD come close, but others don't.
- beebeepka 3y agoMaybe you haven't used sufficiently new AMD laptops. Because my Ryzen 5800H and 6800H laptops (16 and 14 inch) can easily last a day despite using TSMC 7nm instead the much more efficient 5nm process that Apple has been enjoying. Macbooks are fantastic but there is no magic. Manufacturing is extremely important
- throwaway2990 3y agoI have a 5800h laptop and 3-4 hours pails to the 8-10 hours I’m getting on the MacBook for the same workload.
- beebeepka 3y agoNo arguments there. The M1/2 last longer. However, this largely due to TSMC 5nm node. The Ryzen 7800u will close the gap for sure
- formerly_proven 3y agoYou can do that with a 12th/13th gen too, though it depends on what “work” is. I’m not sure there is any laptop that would last a day using the average enterprise setup (two IPSes, three “endpoint protectors”, two AVs, heavy WMI scripts constantly running and MS Teams always open), simply because the thing won’t get under 40% CPU during the day. The advantage of a MacBook here would simply be that 90% of the mentioned software doesn’t exist for the platform.
- fsh 3y agoI have heard the joke that MobileIron (an enterprise software for iOS devices) had its name because it turns you iPhone into a mobile iron.
- ilyt 3y agoGo ahead and actually draw long term CPU load and clocks. You will discover that you're nowhere near full load most of the time.
