Obviously, Intel and AMD are really not following hardware data transmission technology of multiplexers(frequency modulation) and QAM(amplitude modulation) to achieve multiple channels of dedicated packet transfer from CPU to Internet(microkernel instructions).

The many dedicated channels will speed massive parallel communications by segmented data, fast and furious.

Data compression is now by codecs, and the highest ratio of repeated words is Prml used in hdd. Although we have used brain wave(tabled by location in the brain, using wafer scale computer analysers) transmission, which is even more compressed.

So, hardware design has yet to be thought out. Current thinking is way behind in ways of handling analog/digital mixed signals.

Footnote:
Multiplexers are Wcdma, cdma, tdma on carrier frequency. But we are using sub audio frequency to carry carrier frequency for range and attenuation in small space suppressing unwanted reflections.

QAM using lower frequencies for quadratic amplitude transmission is up to 256 now.

Both analog/digital signals can exist in free space as well as in copper or fiber optics.
