I like to play a mental game where I try to figure out the year where a current latest Raspberry Pi is equivalent to the total world computing power. Most of the time I fall asleep before I get very far! ;)
Example: The original Cray-1 could process 160MFLOPS, while a Pi Zero 2 can process 5.1GFLOPS. (via http://www.clustered-pi.com/ http://www.clustered-pi.com/ ) The Cray-1 was released in 1975 with over 100 sold: https://en.wikipedia.org/wiki/Cray-1 https://en.wikipedia.org/wiki/Cray-1 -- So the Pi Zero 2 was roughly 300 times more powerful than a Cray-1, and was roughly equivalent to the world's computing power in 1975.
I leave it up to the reader to work out other comparisons :) https://en.wikipedia.org/wiki/Computer_performance_by_orders_of_magnitude https://en.wikipedia.org/wiki/Computer_performance_by_orders... can be useful to help you figure out the equivalent computing power of various devices.
- hyperman1 5y agoIf you see the stuff Feynmann had to work with when creating the first atomic bomb, just about anything is more powerfull. I always wonder if the CPU used to check if I push the power button on my Senseo coffee maker should be considered technology capable of making a nuclear bomb .
- Retric 5y agoThis is a little misleading due to latency issues etc. I like trying to figure out when you would be better off with say 250 Cray-1’s vs the latest Raspberry Pi.
- johnklos 5y agoI think you're making the same mistake as many other modern benchmarks do: GPU compute != general purpose compute. A Pi Zero 2 is easily multiple times faster than a Cray 1, but not 300 times, except for certain very specific workloads. For general code that does lots of math but isn't GPU accelerated, I bet the difference in performance is significantly smaller.
