> CPU: Dual-core 300MHz ARM Cortex-M4F

It's absolute bonkers amount of hardware scaling that happened since Doom was released. Yes, this is a tremendous overkill here, but the crazy part here is that this fits into an earpiece.

This is the "little part" of what fits into an earpiece. Each of those cores is maybe 0.04 square millimeters of die on e.g. 28nm process. RAM takes some area, but that's dwarfed by the analog and power components and packaging. The marginal cost of the gates making up the processors is effectively zero.

so 1mm2 peppered by those cores at 300MHz will give you 4 Tflops. And whole 200mm wafer - 100 Petaflops, like 10 B200s, and just at less than $3K/wafer. Giving half area to memory we'll get 50 PFlops with 300Gb RAM. Power draw is like 10-20KW. So, giving these numbers i'd guess Cerebras has tremendous margin and is just printing money :)

I remember playing Doom on a single-core 25MHz 486 laptop. It was, at the time, an amazing machine, hundreds of times more powerful than the flight computer that ran the Apollo space capsule, and now it is outclassed by an earbud.

Can we finally end this Apollo computer comparison forever? It was a real time computer NOT designed for speed but real time operations.1

Why don't you compare it to let's say pdp11, vax780/11 or Cray 1 supercomputer?

NASA used a lot of supercomputers here on earth pior to mission start.

And perhaps more fittingly, that PC couldn't decode and play an MP3 in real time.

And by an order of magnitude or more, too!

Yes but also Doom is very very old.

I bought a kodak camera in 2000 (640x480 resolution) and even that could run Doom on it. Way back when. Actually playable with sounds and everything.

Here's an even older one running it: https://m.youtube.com/watch?v=k-AnvqiKzjY
