Apollo Guidance Computer
Reading about the Apollo Guidance Computer. Compare that to the US$3.23 ATtiny85.
| Spec | AGC | ATtiny85 |
|---|---|---|
| Word size | 16-bit | 8-bit |
| Clock | 2 MHz | 20 MHz |
| ROM | 72 KiB | 8 KiB |
| RAM | 4,096 B | 512 B |
The values in the above table are approximate, see the sources listed above for actual figures. Basically the $3 chip is ten times faster than the AGC but with less storage. Call it a draw?
