Say you want to replicate this in 1 month, you need 1320 GPUs for a month. They didn't specify which ones, but say at 1000 bucks per GPU, that's a 1.3M USD investment. And some pocket change for power etc.
There isn't anything new about this result actually, Google just set aside the necessary resources to demonstrate it.
With depreciation over a year, that falls to a USD 100k investment per attack; if realistic to depreciate over 3 years, that falls to USD 30k per replication. Not so expensive on these terms.
