using a raspberry pi 2 to make a game emulator on mac

I ran all of the Raspberries through two fairly standard torture tests, all the while connected to a power supply with a 0.100 Ω precision resistor inline, and recorded the voltage drop across the resistor, and thus the current that the computers were drawing. Even if you plan to stay within the comfortable world of the Raspberry Pi computers, you’re looking at the older Pi 3B+, the tiny Pi Zero, the powerhouse Pi 4B in a variety of configurations, and as of last week, the Pi Zero 2 W.

When it comes to picking a tiny Linux computer to embed in your project, you’ve got a lot more choice today than you did a few years ago.

How many milliamps do you think a Raspberry Pi 4B draws, when it’s shut down? You’re not going to believe it. Indeed, the clickbait title for this article could be “We Soldered a Resistor Inline with Raspberry Pis, and You Won’t Believe What Happened Next”, only that wouldn’t really be clickbait. Most of the time, it runs almost like a Raspberry Pi 3B+, but uses significantly less power.Īlong the way, we found some interesting patterns in Raspberry Pi power usage. If you look at mixed CPU-and-memory tasks, the extra efficiency of the RP3A0 lets the Pi Zero 2 W run faster per watt than any of the other Raspberry boards we tested. The answer turns out to be a qualified “yes”. We’ll see some benchmarks, measure the power consumption, and find out how the new board does. Can it pull this trick off? Can it run faster, without burning up the batteries? Raspberry Pi sent Hackaday a review unit that I’ve been running through the paces all weekend. That’s the gap that the Pi Zero 2 W is trying to fill. But the cost was significantly slower computation than its bigger brothers. The old Pi Zero was great for these self-contained, probably headless, embedded projects: sipping the milliamps slowly. When you’re using a Pi Zero, odds are that you’re making a small project, and maybe even one that’s going to run on batteries. But this custom chip has a secret: it lets the board run on reasonably low power.

While 512 MB of memory is not extravagant by today’s standards, it’s workable. One remarkable aspect of the board is the Raspberry-designed RP3A0 system-in-package, which includes the four CPUs and 512 MB of RAM all on the same chip. Last week we saw the announcement of the new Raspberry Pi Zero 2 W, which is basically an improved quad-core version of the Pi Zero - more comparable in speed to the Pi 3B+, but in the smaller Zero form factor.
