They say 4C and a Model 3 battery pack is apparently 60kWh so that would be 240kW. That's ignoring inefficiency though, so we're talking significant fractions of a megawatt to charge one car.
250 to 350kW chargers are already in common use. And batteries that charge this fast too. What's news here is that they've done it on an LFP battery which is the cheaper kind of lithium chemistry.
Lipo chemistries used in hobby applications are often rated at 5C charging for example versus 4C here.
To get a good comparison in a car we need a manufacturer to actually do the development work and release a car that can be tested in real world conditions. There are the temperature limitations the press release already mentions and also limits to avoid range loss from fast charging over the life of the car.
