Raspberry Pi 5 Thread

Why use a Raspberry pi?

I've been using 4GB Raspberry Pis for almost 4 years now, and they are quite energy efficient in points per watt when compared to my old hardware, such as a Ryzen 2700X. The Pi 5 is the newest version that runs in a similar power envelope as the Pi 4 for DC usage but does more work per watt.

Beyond a low power footprint, for a minimal purchase, I can incrementally add more processing power.

Pi options
The Current version is the Pi 5, which comes with, 4GB ($60), or 8GB ($80) of ram.

There little reason to get any of the older Pis for DC as the pi 5 is more performant and the savings are minimal - a 2GB pi 4 is $45, saving only 15 over the 4GB Pi 5.

I'll be building this thread over time - I don't have all the information ready to roll for bulk upload. Feel free to post and contribute anything you've learned about the pi 5
 
I reimaged one of my pi 4s with the newest Raspbian lite (bookworm), and set up Einstien on it so I could have side by side results with my pi5

Binary Radio Pulsar Search WUs:

pi 5 on einstein:
1500mhz: 11,502 CPU time
2400mhz 10,950 CPU time

pi 4 on einstein
1525mhz: 15,753 CPU time

The pi 5 so far seems to be drawing <5 watt on einstein (my current setup makes it hard to to be definitive at the moment) and extensive testing on the pi 4s has them using 3.84w under full load
 
Interesting. I will have to take some time for comparisons to some of my CPU's and GPU's to see what may be more cost effective to run.
 
The first two tasks completed in 19:28 and 20:04 or 70.1k and 72.2k seconds each.

Compared to my RPI 3Bs in seconds for each of the 3 I have running. I thought they were all clocked the same but they show different times. 5-8 times faster.
