This is a classic and wonderful way to learn and think about the junction of physics and computers. Another one is https://news.ycombinator.com/item?id=702713
Since then the ratios increased (L1 to RAM by quite a bit), SSD became common, and networks got intermingled with everything.
The transatlantic ping is waves traveling at the speed of light in fiber and a large fraction of the speed of light in copper. To send a pixel to a screen you need to wait for the next vsync if you're not using a variable refresh rate display. That alone can be double digit milliseconds. Then you need to wait for the crystals in the screen to physically move in response to applied voltage. Moving things is slow. Movi…

Furthermore, if I’m reading the RTINGS.com source posted below correctly, modern LCDs have smaller latencies than a transatlantic ping. So not only is it not obvious, it’s no longer universally true.
I have always been crying about latency computing for years. My earliest HN comment on the topic was in 2012. And I have been ranting about it for even longer outside I really hope at the later part of this decade we start focusing on latency computing instead of bandwidth. From Display, Input, Output and Network, and down to OS and Software. I had always hoped VR would forced those optimisation due to VR being a lat…

If you have a good condition Trinitron like display these days (Mitsubishi diamondtron, sony pvm, etc) it is presently appreciating in value every year.

VR never happened? Someone needs to let Valve and Oculus know..

Gosh that's a fun read in all sorts of ways. SSDs are relatively new, there are hold-outs, and they cost $300 for 80GB!

That image would be better by having an year tag. Since then the ratios increased (L1 to RAM by quite a bit), SSD became common, and networks got intermingled with everything.
