Not really.

It's the XsX that is actually designed to run always at the highest frequencies possible, that's why it has fixed frequencies. And if it has to increase its power consumption to achieve that, it will do it.

On the other side, the PS5 is designed with a maximum power consumption limit in mind, even if that means lowering the frequencies to not trespass that limit.

I'm just repeating what Mark Cerny said. Instead of letting the load dictate the power. They have a constant power and worst case scenario they've designed to. So the system can handle being at full frequency without the cooling or power supply being under stress. The frequency goes down i less demanding games but you can utilise 100% frequency for a game. 

I'm just repeating what he said.

And I'm not saying that Cerni lied, but he did some PR talk to make it look great while hiding some of the shadows.

The Digital Foundry article that has been posted several times on the thread explains it a bit better:

Put simply, the PlayStation 5 is given a set power budget tied to the thermal limits of the cooling assembly. "It's a completely different paradigm," says Cerny. "Rather than running at constant frequency and letting the power vary based on the workload, we run at essentially constant power and let the frequency vary based on the workload."

(...)

It's a fascinating idea - and entirely at odds with Microsoft's design decisions for Xbox Series X - and what this likely means is that developers will need to be mindful of potential power consumption spikes that could impact clocks and lower performance.

Also, no, it doesn't mean that it will frequencies in less demanding games. It means that if both the CPU and GPU have to run at 100% capacity and they reach the thermal limit, one of the two parts (likely the GPU) will have to lower their frequency until the spike is gone and can go up again.
