Lots and lots of wire, yes, with each one cut to a specific length so that all of each gate's input signals arrive at the same time. That's why the backplane looks like a mess of wires hanging down due to seemingly being way too long.
- dragontamer 3y agoNote that modern RAM has length matched traces. Take a look at all the PCB traces near RAM and CPU. You can see them 'squiggle' looking for matching-space at either end of the RAM/CPU connection. PCBs make things like consistent length matching easier. All circuit boards have near identical lengths, controlled impedances and other features that support ... Well... Effectively 6-billion baudrates for DDR5. 6000Mhz DDR5 with 64-bits per half-clock (3000Mhz clock so 6000 transfers per second) has a bit every 5 centimeters or so.
