Apollo 11 vs USB-C Chargers

I think it is healthy to compare historical and modern computing. Let's see how the CPUs contained in recent USB-C wall chargers compare to the power of the Apollo 11 Guidance Computer (AGC). The Apollo 11 spacecraft carried 3 humans to the moon and back in 1969.

"The CYPD4225 is definitely not rated for space. I have no idea if it would work in space."

This is fun, but also detailed. USB-PD chargers need a microcontroller to do power negotiation. So how powerful is a USB-C PD charger compared to, say, the Apollo 11 guidance computer? Forrest Heller goes into some detail - not just comparing clock speed, but also looking at memory, and clock-cycles per operation.

Favorite tweet:

Sure everyone knows their phones have more computer power than the computers used to land people on the moon. But did you know your phone's *Charger* probably has more CPU power than the computers that controlled Apollohttps://t.co/n5FsfvLcN6 pic.twitter.com/UvpRvVemfV

Reminder that the USB-C spec is an eldritch horror as well.

All the computers on Apollo 11 are less powerful and have less memory than an Anker PowerPort Atom PD 2. I'm going to assume that the LVDC and the AGS do not use any exciting instructions that would be difficult for a Cortex-M0 to perform - besides division. I will hand-wave this away by saying that division probably takes longer than multiplication. And I have listed the multiplication times above. The CYPD4225 can comfortably execute thousands of arithmetic instructions in the time it takes any Apollo 11 computer to execute a single multiply.

It's very tempting to claim that the Anker PowerPort Atom PD 2 could fly me to the moon. But we need more analysis. What if the Apollo 11 Guidance Computer contains dedicated hardware which missing in the CYPD4225 and cannot be replicated in software? Let's compare the CYPD4225 to the Apollo 11 Guidance Computer. I'll be using the excellent Virtual AGC documentation as a reference.

"I claim that we would only need the compute power of 4 Anker PowerPort Atom PD 2 USB-C chargers to get to the moon with the following caveats:
- The CYPD4225 is definitely not rated for space. I have no idea if it would work in space.
- I did not examine the peripherals used by the Apollo 11 computers. The CYPD4225 has 30 GPIO signals and talks UART, I2C, and SPI. However, how many peripherals did the Apollo 11 Guidance Computer support? 100? 10? More Googling is needed. And probably the voltage levels from the 1960s are too high to connect to a CYPD4225."
