with the current shortage in RPi availability, I found myself looking for good deals of second hand computers.

Basically, I only want the RPi to perform computation and act as a server, nothing more, nothing related to sensors or anything. Just computations.

I would like to know how to compare computing performances between what I would get from a RPi4B 4G Ram (or equivalent CM4) and a cheap second hand laptop with 4G RAM from 2008 that I was able to setup with Ubuntu after upgrading the 320Go corrupted HDD to a 1TB SSD.

Here are more specs:

  • Intel Core Duo T5850
  • Graphic Card NV86
  • Wifi

Thanks.

I would prefer the Raspberry Pi for the following reasons:

  • The Raspberry Pi is very efficient. With about 5 - 10W load the electricity costs land in about 10-25€/year (In Germany), your laptop should burn much more power.

  • The Raspberry Pi clocks only with 1.5 GHz but has 4 cores. It depends on what you want to calculate. If the calculation can only use one core, the laptop with 2.6 Ghz will be better. If the program can use several cores at the same time, then the Pi has the advantage.

  • The Pi also has WiFi and the graphics should run on the same level.

  • The Pi also manages without active ventilation. (As long as you take a good case).
