My less-than-one-year-old Core Ultra 9 275HX was supposed to be much more power-efficient than previous generations, but I’m not impressed with it at all. Yes, it’s a gaming laptop, but why does it need 70 watts just to idle? And when playing Factorio with a CPU-heavy save, the PC uses 170 watts, while my M5 uses 50 watts on the exact same save. I don’t know how much the CPU alone is to blame for this, but I’m tired of x86 and Intel. My Linux laptop/server with Ubuntu and an AMD CPU is somewhat better (Also a gaming laptop), though. It’s only drawing 25 watts while idle while hosting six web services. So, if I were to go by just my anecdotal experience, having used about 10 different laptops over the last five years, Macs are just in another league when it comes to efficiency. However, the AMD/Linux combination is getting somewhat better at a slow pace, while Windows/Intel is stuck with terrible efficiency.
