| The reduced horsepower relative to M-series isn't a problem for me as much as efficiency is. Both Intel and AMD seem to struggle with building a CPU that doesn't guzzle battery without also seriously restricting performance. This really sucks. The nice thing about high end (Mx Pro/Max) MBPs is that if you need desktop-like power, it's there, but they can also do a pretty good job pretending to be MacBook Airs and stretch that 100Wh battery far further than is possible with similarly powerful x86 laptops. This affects ultraportables too, though. A MacBook Air performs well in bursts and only becomes limited in sustained tasks, but competing laptops don't even do burst very well and still need active cooling to boot. On the desktop front I think AMD has been killing it but both companies need to start from scratch for laptops. |
It may be the software problem as well. On Windows I regularly need to find which new app started to eat battery like crazy. Usually it ends up being something third-party related to hardware, like Alienware app constantly making WMI requests (high CPU usage of svchost.exe hosting a WMI provider, disabling Alienware service helped), Intel Killer Wi-Fi software doing something when I did not even know it was installed on my PC (disabling all related services helped), Dell apps doing something, MSI apps doing something... you get the idea.
It seems like a class of problems which you simply can't have on macOS because of closed ecosystem.
Without all this stuff my Intel 155H works pretty decently, although I'm sure it is far away from M-series in terms of performance.
