Eben Upton, by surprise, annunces the new Raspberry Pi 5. The benchmarks show a computational power between 200% and 300% more compared to Raspberry Pi4. Very interesting! |

Recently swapped mine over from PrimeGrid to WCG and Rosetta, and it seems to be ticking along nicely at an overclock of 2.75GHz. Above that it is a little unstable I find (although I can push it to 2.95GHz). Average temp with the active cooler is 70-75C, and I think it averages around 20-25 GFLOPS (across four cores) for 13W of electricity per hour :) |

With a 2ghz OC mine runs around 65c, since I like to use my Raspberry Pi's (I have a 3 , 4, and a Pi 5) for other experiments as well, I have been reluctant to stress it too far.... I may push the 4 a little further, but I'd hate to damage the 5 at this stage.... |

I find somewhere around 2.8GHz work-units start failing for compute errors - although the temperature is stable. 2.9GHz tends to just be stable, and above that there’s never any guarantee it would boot, and if it does it’d quickly end up being throttled automatically to keep it below 85C. I’ve seen some articles online where people have pushed them up to 3.1GHz. Very much depends on the chip I suppose, and I doubt it’s a “useful” 3.1GHz for scientific work. I plan on buying more RPi5s over time, so it’ll be interesting to see if the chips get better and more stable at higher clocks. Will also be interesting to see how long they last crunching 24/7! They might also be brining out a Compute Module for the Pi5 at the end of this year… :) |

They have thermal protection so I can't see the chips getting damaged even at silly-overclocks. The weakest link in my mind is the capacitors, the warmer they are, the shorter their life. With the early Pi4's the PMIC gets very hot and might transfer their heat to nearby capacitors, the later Pi4's with the newer PMICs are much better. I'm in two minds about the value of Pi's on boinc now, there are 16 thread mini-pc's around at considerably higher performance and the same order of energy efficiently. Plus many projects don't support Pi's On boinc I'm currently running three Pi4's, one Pi5, three i7-4790S and two ryzen7 5800H. The 4790S's have to go because of energy efficiency although they are brilliant reliable workhorses. |

Took a look at Amazon and I was able to find several mini-PC's in the sub $400 range. Gotta be honest, I'm seriously thinking about buying one just for BOINC projects... |
