Does my key fob have more computing power than the Lunar lander?
buzzsprout.comThe contactless chip in your credit card is a full computer that powers up via inductive charging when tapped. It then negotiates 2 way public/private key encryption to verify you. These usually run jme which requires a lot more power than the lunar lander.
Another good one is the many little computers on cars such as the TPMS sensor in each tyre valve.
TL/DL: yes, it does, and by significant amount
Key fob has nRF52840l, 64 MHz ARM, 1024 KB Flash, 256 KB RAM
Apollo Guidance Computer was 2MHz, ~72 KB ROM, ~4 KB RAM
The comparison might be up to 10x different due to more efficient architecture and different MIPS/MHz ratio, but it does not change much, since the differences are so dramatic.
(This is based on links in the podcast description, which I assume what they talked about. Those pretty new keyfobs, older ones might have something like nRF24LE01, which is only 16 MHz, 18 KB Flash, 1KB RAM)
That said, the lunar lander still leads the keyfob in peripherals.
I guess even a disposable vape has more computing power than the Lunar lander. (I don't know if that's more or less ridiculous than a key fob, but at least a key is not so disposable.)
Car chargers for usbs, or digital thermometers, or disposable pregnancy tests - it's absurd the amount of compute that ends up even in single use or trivial products.
Never mind the car charger, what about the cable itself?

A keyfob is more analogous though - i.e. a computing device used to control a vehicle.
The keyfob was brought up by someone so they can make a clickbaity title: "A thing in your pocket has more computing power than Apollo guidance computer. And it's not your smartphone"
Here's something to bake your noodle:
Apple makes Lightning to HDMI dongles that contain 400 MHz Samsung ARM SoCs and 256 MiB of RAM onboard.
They run frickin' Darwin.
There is more power in one of those dongles than there was in the OG iMac, and it runs a cut-down macOS. No cap.
And yes, Doom has been ported: https://m.youtube.com/watch?v=4XCkeN0XuqA
This is actually a good example to consider why a better computing model does relatively little to enable some things. Sure, your fob has more computing complexity; the lander had far more of, well, everything else.
The way I first heard this was regarding Voyager.
Something akin to: "Right now, you're carrying more computing power than what's on Voyager. And I'm not talking about your phone, I'm talking about your keyfob."
Isn't the real challenge finding anything made today that has less compute power than the lander? I challenge you to find that.
Another related question: Is there any production software system so inefficient that it would run faster if implemented in machine language on the AGC
You can still find things like an Arduino Micro that has less ROM & RAM than the lunar lander.
But finding something new slower than a 2MHz CPU is probably a challenge nowadays; even the Micro is 16MHz and can probably be overclocked a ways above that without much work or risk.
https://www.amazon.com/dp/B00AFY2S56 - not that that is necessarily the best way to buy such a system, just showing they exist.
That's easy. The challenge would be finding something that has less than the lander, but more than zero.

In fairness, the cryptography backing key fobs is likely more computationally intensive.
Does my key fob have more computing power than the Lunar Lander? In this episode of Runtime Arguments that just dropped today, Wolf and I dive into that question and we reveal some information that might surprise you. We had a lot of fun doing the research and we hope you enjoy it. Find it wherever you get your podcasts. And, if you enjoy it, please tell all of your friends. We'd really appreciate it.
I will give it a listen! :)

Right? And not even a way to get a transcript, that I can see. Who has an hour to listen to some dudes talk about a question that could and has been answered in a few seconds?
Insomniacs.
How long until we can ask that question of USB cables?
You are more than 5 years late.

There are ones that do, they are just... the naughty kind
Low cost ARM M series microcontrollers are ubiquitous, and they're all immensely more powerful than the lunar lander computer.
We have all these amazing technological resources and yet, houses are still out of reach for like half the population.
I’d love to see some disruption of those markets. Let’s see … laws that promote rather than restrict development … search programs that reduce friction identifying maximum buildable area lots for sale … trading platforms for combining lots into larger developments … optimization of actual building technology … innovation in ownership and governance models…. Of course, none of those are strictly dependent on MHz.
Making houses 3 orders of magnitude smaller and cheaper isn't very popular.
But I get your sentiment.
The problem isn't the houses themselves, it's the land to put them on. Technology doesn't help much with that.
