What ultimately matters is ROI, output/performance per 1w. ( if we ignore the cost factor ). In that perspective Intel NUC is way ahead than Raspberry PI. So why waiting if Raspberry Pi is out of stock.
Power is just a bit higher than Raspberry PI,
- NUC with Ubuntu 22 ( i5 , 16GB, SSD ) – 7.2W
- Raspberry Pi is with Raspbian ( Model 4, 8GB ) – 4.8W
- Both running LAMP stack
