I'm running BRPS on two

I'm running BRPS on two Amazon Fire TV sticks. A Fire TV stick 3rd Gen, and a Fire TV stick Lite. Both have a 4 core A53 at 1.69mhz. I'm using 2 cores per stick, 100% cpu usage, 90% memory. A task takes a bit over 40k secs. 3 cores at 100% causes throttling and is less effective than 2 cores. I haven't tried 3 cores with less than 100% cpu usage, I assume this might allow for some increase in throughput. I plan to try some sort of cooling. With just two cores, heat seems minimal. 

Setup is simple: sideload Boinc from Fdroid, then use ADB shell to turn off sleep timer. 

Anyone else running Fire TV sticks?

You may want to cool them as much as possible.

I remember someone reporting high burnout rates because they were not designed for 24/7 and got too hot.

Welcome to the ARM brigade. :)

I am running some elderly kindle fires.

I have some related

I have some related questions.

  1. What is the top producing, volunteer priced Arm CPU system?
  2. Is there any Arm CPU system out there compatible with Nvidia RTX 3000 series gpus?
  3. Are there any Arm/Nvidia compatible e@h applications?

While I am sure that with an unlimited budget something could be assembled I don't have an unlimited budget. :)

So?

There are several Pi cluster

There are several Pi cluster systems running.  I doubt they equal the performance of a single RTX 3000 though.

There is the custom BRP application by Gaurav Khana that runs on my Nvidia Jetson Nano device.

It uses a ARM57 processor core but has 128 Maxwell CUDA cores that run the BRP4/4G tasks pretty well.

I am trying to put together a Jetson TX2 NX module with 256 Pascal cores that I hope to have even better results with.

I'm currently running a

I'm currently running a couple of BitScope Edge Cluster 12's. They hold 12 x Pi's each. Pics HERE

I am using a couple of LED transformers to provide the power (24v) to them. The power circuitry in the Edge Cluster drops that down to something the Pi's can use. The EC can take anything from 9v to 24v, but I figured higher volts means lower current needed.

They aren't cheap, but it does package them up into a neat little box that handles the power and cooling. They also make larger rack-style systems if one wants more than 12 per box, but I had 12 Pi4's which is why I went with the first EC12.

That Jetson Orin Nano looks

That Jetson Orin Nano looks appealing at $199.

I got the Jetson TX2-NX up and running to join efforts of my original Jetson Nano.

Basically twice as fast and 50% more cores. Running the BRP4/4G tasks and whatever ARM64 cpu apps I can find on projects.
