The speed of light in an optical fiber is still only about 2*10^8 m/s - ddr5 6000's 3ghz clock means it still only travels 6.7cm/clock - so there'll still be difficulties around latency if it's not "close", and that's ignoring any issues of actually getting optical transceivers on the die itself.
- billti 3y agoIt blew my mind when I learned that even if you could hand wire conceptually perfect switches and wires, once your board was over a few inches, the laws of physics (e.g., the speed of light) would mean you still couldn’t beat a modern CPU for clock speed. It really is insane the level at which current hardware works.
- josephg 3y agoYeah. Any time I wait for my computer to do something I think about this. In the 4 seconds discord took to open, my computer could do what, 5 billion operations per second per core? Even single threaded that’s 20 billion steps? And my internet connection could have delivered 600 million bytes of data - enough for a complete copy of windows xp. It’s wild.
