    Geerling also demonstrated that the 2GB Pi 5 comes with a couple of unexpected benefits that Upton didn’t mention in his announcement—that the 2GB Pi 5 runs a little cooler and uses a little less power than the 4GB and 8GB editions. The 2GB Pi used just 2.4 W or power at idle and 8.9 W during a CPU stress test, compared to 3.3 W and 9.8 W in the 4GB version. The SoC of the 2GB Pi measured 30° Celsius at idle and 59° under load, compared to 32° and 63° for the 2GB version. Those are all small but significant differences, given that nothing has changed other than the SoC.

    As to the exact functionality that was removed from the chip for the 2GB version of the Pi, the company hasn’t gotten specific. But Geerling speculates that it’s mostly related to functionality that’s being handled by the custom RP1 I/O chip—RP1 handles the Ethernet and USB controllers, display interfaces, and GPIO, among other things.


    So is it worth stepping down to a 2 GB Pi 5 just to get the simpler D0 chip? No. But is it cool to have a cheaper 2 gig option exist? Yes. Just make sure you have a use case for it that doesn’t need a ton of RAM.[1]

    This process should work on any Intel Mac pre 2018 (without T2 security chip & secure boot). Thanks for the suggestion to install Linux on this old MacBook Air! It has brought new life to this old computer and I am really enjoying getting to know Linux, as I have never really used Linux in this capacity. Let me know if you would like a more in depth video of how I set up my Linux environment!

    Oh, thanks for the link!


    Edit: added a bit of information below for those interested

    A/B testing (also known as split testing or bucket testing) is a methodology for comparing two versions of a webpage or app against each other to determine which one performs better. A/B testing is essentially an experiment where two or more variants of a page are shown to users at random, and statistical analysis is used to determine which variation performs better for a given conversion goal

    In an A/B test, you take a webpage or app screen and modify it to create a second version of the same page. This change can be as simple as a single headline, button or be a complete redesign of the page. Then, half of your traffic is shown the original version of the page (known as control or A) and half are shown the modified version of the page (the variation or B).

    The following is an A/B testing framework you can use to start running tests:

    1. Collect data:
    2. Identify goals:
    3. Generate test hypothesis:
    4. Create different variations:
    5. Run experiment:
    6. Wait for the test results:
    7. Analyze results:
