I don't know why you think Sony would increase the PS5 power consumption nearly 2 years after release and doing so may break the PS5 chip logic.I don't think Sony cares about your energy bills. I think with the PS5 design their inital target was ~220W for the box + cooling system + PSU. But the dynamic clock system was a completely new feature, never done before in a mass produced item, so they needed time to fully test at ~200W before committing with their initial target.
"With this new paradigm, we're able to run way over that. In fact we have to cap the GPU frequency at 2.23 GHz so that we can guarantee that the on chip logic operates properly."
Not only that, in an interview with Digital Foundry and Mark Cerny.
PlayStation 5 uncovered: the Mark Cerny tech deep dive
Cerny said this,
"There's enough power that both CPU and GPU can potentially run at their limits of 3.5GHz and 2.23GHz, it isn't the case that the developer has to choose to run one of them slower."
So if there was already enough power to run the chip at it's limit, why would Sony increase power draw?
This is why I put Austin's power consumption results into question.
