They blew an incredible amount of effort and money on new processes that didn't pan out. The failure rate was too high for production. AMD doesnt fab their own chips so they can piggyback on the progress unlocked by the fabs that build for cellphones (TSMC in this case).
Also, transistor density is a better measure than 5nm/7nm/10nm. That feature detail in nanometers is more or less pure marketing term and doesn't compare accurately. Intels transistor density is still better than the latest Ryzen but it looks like they will be matched or surpassed by the next gen AMD.
