Raspberry Pi 4 Memory

Raspberry Pi 4: Chronicling the Desktop Experience – Memory Usage – Week 14

Last Updated on August 20, 2020


Wolfram Mathematica

One of the unique plus points of Raspbian over other distributions that support the RPI4 is that you’re given a (free to use for non-commercial purposes) license for Wolfram’s Mathematica.

Mathematica is a symbolic mathematical computation program, sometimes called a computer algebra program, used in many scientific, engineering, mathematical, and computing fields. I’ve only used this software infrequently over the years, as I prefer not using proprietary software unless there’s no open source equivalent, or if the proprietary program is far superior. Mathematica has been available for previous series of the Raspberry Pi. But the RPI4 is the first to  offer a 4GB RAM model.

I’ve only tested Mathematica briefly. Running the Benchmark Report uses 91MB for the Mathematica process, and 291MB for the Wolfram Kernel. In total, about 382MB of RAM running a fairly simple set of 15 tests.

For your interest, the RPI4 scored 0.17 in the Benchmark Result. That’s very slow compared to any desktop processor I’ve ever used in the past decade.

The chart below compares that result with a variety of popular processors. The Benchmark only uses 1 of the RPI4’s 4 cores.

If you want a copy of the full report notebook (WolframMark-Report.nb) let me know.

I prefer the open source RStudio powered by R. Sadly, Raspbian doesn’t provide a RPI4 package for RStudio. While the source code for RStudio is available, I’ve not been able to compile it. And from my research, no one else has.
