If you used a PI Zero with an ethernet expansion board this goes down to 100ma at idle. 6x less. You still get 1ghz cpu and 512mb of ram. I could even run django and postgres on that.
Certainly you don't need gigabytes of ram to run the blog. :)
They saturate the SD card SPI almost to the byte/second.
32-bit is enough forever, specially when you only have 1GB, but I'm staying on 32-bit on my 8GB RPi 4 too, because 4GB per process is enough when you also need the OS to have ample RAM.
If you are lucky enough to have some ARMv7 RPi 2 and/or Rpi 4 8GB, they will be priceless for eternity.
The thing I don't understand tho, is why they didn't chose this Soc for the Pi Zero original, instead of using the already decade-old ArmV6 CPU.
Thus why they bounded the 512MB ram in the package for Zero 2.
Physical limits are now everything you'll see until the end of time.
8GB is the largest RAM you will ever get in one chip.
1TB is the largest Micro SD.
Etc.
BCM2836 is the real deal, peak SoC for non GPU + SD card duty:
I thought 32-bit limited the entire system to 4GB of memory (all processes + kernel), not just per process?
As mentioned in that article, Windows limited it to 4GB if you weren't running Server Enterprise, but Linux generally has it enabled by default.
