This USB-C Charger's Chip Is More Powerful Than the Apollo 11 Flight Computer:

As we celebrated the 50th anniversary of the moon landing last year, the Apollo Guidance Computer (AGC) became a particularly juicy target. The analysis, of course, showed just how much more powerful the chips used in common smartphones are than the computers that got us to the moon. Not too shocking, but amazing nonetheless.

For fun, Forrest Heller, a software engineer at Apple who previously worked on Occipital's Structure 3D scanner, thought he'd cast around for a different comparison. How would far more basic chips, say, the ones in USB-C chargers, compare to the AGC?

Heller took a deep and detailed look and came to a fairly startling conclusion—even these modest chips can easily go toe-to-toe with the computer that got us to the moon.

[...] Now, this isn't to slander the Apollo Guidance Computer [(AGC)]. Not at all. The AGC was amazing.

Without the AGC, no human pilot could have kept the Apollo spacecraft on course to the moon and back. Probably most incredible was how much it did with how little. You might say a USB-C charger is the opposite: Notable for how little it does with how much.

And that's really the point, isn't it?

      Shielding's been invented. Cosmic rays interact with matter - if you want the matter that matters to not be interacted with, just put more other matter around it. You can attenuate the noise by 5 orders of magnitude just by putting it inside a kilo of shielding (the working part of the chip itself is a hundredth of a gram). Or you could buy a system with the milspec version of the chip: http://mil-embedded.com/articles/armed-ready/ . Or you could have 3 of the systems, and vote on the output (which is what happens inside the memory subsystems of milspec chips typically). These are solved problems.

        Radiation isn't your only enemy in space: since the only way to transfer heat in space is by radiation (a singularly crummy way to do it) high-performance, hot-running circuits are difficult in space applications. I suppose that's another reason why the hardware used in space applications generally tends to be 20-30 years behind the terrestrial state of the art. For example, the CPU of the New Horizons probe is a MIPS R3000 that runs at around a third to half of the clock speed of the original PlayStation's CPU. The ESA Solar Orbiter launched just last week uses CPUs that are comparable in performance to those used by Sun workstations from the late eighties (SPARC V7 and V8). The Cassini–Huygens probe used a MIL-STD-1750A CPU, a 16-bit microprocessor whose design dates to 1980.

          You still have conductance and convection inside of the spacecraft. And in a spacecraft actively expending significant mass of propellant, you can dump heat to the propellant (otherwise chemical rocket engines would be a really bad idea). If you don't have that, then yes, heating the universe via heat radiation is it.

    Almost every new computer is more powerful. Your car has a more powerful computer, likely multiple of them. The crappy PineTime [pine64.org] which is orders of magnitude slower than Apple Watch is more powerful than the AGC.

    Next in line could be nanobots. Trillions of individual disposable injectable nanobots, each more powerful than the Apollo Guidance Computer so they can scan things and zap them with lasers.

    The good news is that computers have improved greatly in the past 50 years—by 7 or 8 orders of magnitude. The original AGC budget was 1 cubic foot, 100 pounds and 100 watts, btw. The bad news is that we now have lunar-mission capable computers in our cables. Another place to hide malware. How can any organization audit all its cables? It’s the computer security version of the coronavirus, easy to spread, hard to diagnose and potentially deadly.

    Aerospace hardware is generally rated for reliability under far harsher conditions than hardware intended for terrestrial use, and as such it's usually several generations behind its terrestrial counterparts. For example, the ESA's Solar Orbiter uses the ERC-32SC [cpushack.com], a radiation-hardened SPARCv7 architecture processor which runs at 25 MHz and fabricated with a 0.8 µm CMOS process. Technology like that was considered state of the art around 1987... That for a space probe that was launched just last week! Too bad that Sun Microsystems is now defunct, as we now have a space probe running on a SPARC microprocessor similar to those they designed and used in their old Unix workstations literally off to study the sun. Reliability is far more important than high performance in such applications, and there's only so much performance you can get when your hardware has to endure the temperature and radiation extremes of space. It's thus not surprising that even the most mundane modern-day hardware is so much more powerful than the hardware used for the Apollo program.
