Pi 4, depending on the environment, also needed active cooling, in my experience. Especially in summer, with room temperature above 28*C, it couldn't handle any load until I added a fan. (The good thing about it was that I could control the fan with PWM easily - it was fun :))
- nottorp 2y agoBut the Pi 3 didn't. You'd think with the process improvements they'll be able to have more performance in the same heat envelope, but they want to do their own Pentium IV...
- rbanffy 2y agoProcess improvements can only go that far - register banks, speculative execution, instruction reordering, many execution units and so on use power, but are needed because the processor can be faster, but the memory is still much slower.
- nottorp 2y agoI'd agree except the laptop i'm typing this on seems to use 4.5 W right now, the whole system :) I don't expect Apple like power/performance ratio from everyone, but they could at least try...
