China solves 'century-old problem' with new analog chip that is 1,000 times faster than high-end Nvidia GPUs (www.livescience.com)

"The new device is built from arrays of resistive random-access memory (RRAM) cells.... The team was able to combine the speed of analog computation with the accuracy normally associated with digital processing. Crucially, the chip was manufactured using a commercial production process, meaning it could potentially be mass-produced."

Normal one and zero transistors can hold their state for a while only needing refresh cycles at intervals.
Seems logical to me that it's harder to hold values of greater variance, which is probably also why everything works with binary systems, and not a single vendor has chips that use bits with for instance 3 or 4 states.
What would be most obvious if this wasn't a problem would be to make a decimal based computer. There's a reason we don't have that, except by using 4 bits wasting 6 values, which is very wasteful.
