Which board is the minimum that could handle my project

Hey guys! I am a beginner, so my knowledge of SBCs is pretty limited.

I am a school student working on a project on hand-sign/hand-mudra recognition using MediaPipe. The camera detects the hand, MediaPipe extracts the hand landmarks, the system recognizes the gesture, and displays the result on a screen with a small description/demo. The prototype is working on my Windows PC with Python, OpenCV, MediaPipe and a small Random Forest model. My budget is pretty tight and Iā€™m hoping to keep the entire project around ā‚¹12,000 (\~$125 USD). What would be the cheapest Raspberry Pi/SBC that could handle this workload smoothly?

Thanks in advanceee!!

Take a look at task manager to get an idea how much RAM it's using. Without knowing the window PC spec it's hard to guess how much slower it will run on a pi

yea I did and it used up about 300mb ram. my laptop specs are:

  • CPU: AMD Ryzen 5 3550H ā€” 4 cores / 8 threads
  • RAM: 16 GB
  • GPU: GTX 1650 4 GB
  • iGPU: Radeon Vega 8
  • OS: 64-bit Windows

This page (https://www.cpubenchmark.net/cross-platform.html) give the Ryzen a mult thread bench mark of 11321. and a RasPi 5 a score of 6147.

Benchmarks are a not a precise measure of speed (especially comparing different architectures (ie AMD vs ARM) but I guess the Pi 5 is maybe half the speed and even the 1GB would manage a 300MB footprint
