I just mean that cells in an organism experience much higher noise rates than a CPU, but we still consider them as capable of sophisticated computations. It's hard to peg a number at exactly how much more, but at least for reference many bacteria have a gene transcriptional error rate of like 10^-4. Apparently fiber optic engineers target 10^-12 error rate, and I assume the error rate of transferring data between CPU registers is even lower. So it's probably a decent estimate to think that biological "computations" occur under at least a million times more noise than a computer.
Can you share what you mean by this?
