"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."

So you list the reasons for imprecision: noise, losses, repeatability problems (there are more), but still consider it precise?

Adding two containers of water is only as precise as you can get leakage under control, and can rely on a repeatable shape of the containers. Both is something chip level logic simply does not deliver.
