Hi everyone! Speaking of

Hi everyone!

Speaking of crunching on ARM, I did a test how well does the new Pi 5 crunch E@H in comparison to the previous model.

TL;DR: The Pi 5 is roughly 30-50% faster than Pi 4b.

For more than one sentence, check out my blog post, hope you will find it interesting:

Thank you for a thoughtful test of Arm crunching.

Good benchmark analysis.

At $1500 with CPU, using ddr4 memory and PCIe 4 it isn't cutting edge. But it's price range makes it competitive for boinc users who also are willing to buy rome generation Epyc products.

All this ignores the issue of what CPU apps it may be able to run And if it can run any GPU apps.

The few projects with ARM64

The few projects with ARM64 apps could run the cpu.  But I only know of my custom BRP4/G application at Einstein as the only ARM based gpu application.

And it is out of stock. :)

My snapdragon 8 gen 2

My snapdragon 8 gen 2 (Samsung S23 Ultra) takes almost 5hours to compute a BRP4 task (single thread), 1/8 the size of BRP4 tasks that goes to regular x86 cpu's.

 

Is this the compute time one should expect? or is it really slow?

Don't know where that

Don't know where that hardware falls out in the ARM generation comparison but my Pi4 takes half that time to compute a BRP4 single thread.

This is it. https://einsteinathome.org/host/12932108/tasks/4/0

How many tasks are you running at once? What else are you running at the same time?

Is the battery getting too hot? It suspends above the threshold you set.

Does it run all the time or suspend when you are active?

Those are the things that effected my android crunching.

Just got my new Raspberry PI

Just got my new Raspberry PI 5!  Thinking of installing boinc on it just to see what it can do, or has someone else beat me to it?
