Apple doesn’t talk about the RAM because the machines have enough. I don’t recall the exact amount from tear downs, but having owned a few different models over time and played graphically complex games etc on them, I can say the performance on iPads is consistently great and however much RAM they have is enough. iOS is a console ecosystem, so any new one is guaranteed to last 5 years or more with excellent performance.
