I want to get more than the most possible performance out of my pi 4b. I was looking around, and I saw it was possible to get just the processing unit for the pi 4 without the rest of the pi. I looked on the web, and I found NOTHING even close to "how to add a second processor to a pi 4b". Is it even possible? If so, how would I go about it?

1 Answer 1


It would be extremely difficult if not impossible. There is no provision on the Pi 4b board for a second chip, and the hardware isn't designed to support a second chip.

One reasonable approach to increasing Pi computing power (for certain computations) would be to purchase several Pi4 boards and set them up with HTCondor or a Beowulf-like configuration.

  • I would suggest doing a search to see what others have done. Clustering RPis is usually done as an academic exercise or as a convenient software development system...
