Looking for more processing power

Post by N6VL » Mon Apr 22, 2019 3:47 pm

I’ve been using a Zumspot for several months now. It’s from HRO and has the Pi Zero board. It’s been brought to my attention it lacks processing power. Noticed it takes about a full minute to restart when updating a configuration setting.

What Pi boards should I be looking for to increase raw speed?

If you're running Pi-Star 3.4.x, the best board is the Raspberry Pi 3B.

If you're running Pi-Star 4.0.x, the Raspberry Pi 3B+ is the most powerful, though it runs hot. A good alternative is the new Raspberry Pi 3A+, which gives you a lot more processing power than the Zero W, but also runs a lot cooler than the 3B+. The only downside of the 3A+ is that it has fewer ports (1 full-size USB vs 4 for 3B+) and no Ethernet connection. If you use WiFi, that's not an issue.

There's a good related article comparing the RPi 3A+, 3B+, and Zero W by Bud, W0RMT:

If you want a powerful board go with an odroid ux4. and a shifter adapter board to match the pi header.
Both 3.7.** and 4.0.0 run on it without complaint, and it really has got some horsepower.

My humble Pi Zero W (Chinese MMDVM board) boots/reboots in half the time of my 3B (DVAP dongle on USB). Both have the same 3.4.17 Pi-Star. The Zero runs cooler too.

Both use SanDisk 16GB Ultra Class 10 cards.

As to why the Zero appears to perform better is a mystery...
