what is not clear to me is how you can exclude ambiental temps from the equation?!
i live in catania, one of the most hotter city in italy during summer (and the rest of the year tbf), the difference between my room and a room in a far colder city it's gonna be around 20+ °celsius or more, how can a system don't take in account such a giant difference in external temps? also majority of people (me for example) never clean their console, isn't accumulated dust during the years have some sort of hit on internal temps?
serious question, not trolling.
I never exclude ambient temps. I only said, either Sony provides a aio cooler or it wont run sustained 2.23ghz.
Anyway in further postings since, it just seems Sony is doing load balancing between CPU and GPU using AMD smart shift and probably Sony's own profile from their large library of old games. Mark Sony sure like to repackage simple things.
So my guess, Sony designates a fix tdp, i expect about 280w (gpu = 250w, cpu 30w), design their cooler for 300w tdp dissipation.
To run 2.23ghz, developers have to assign the full 250w or more to the gpu.
There are rumors of 7nm+ rdna2 gpu can run higher clocks and rdna2 have a 50% perf/watt improvement over rdna1.
So the 5700(PS5 predecessor) can be softmod to run 1.9+ghz at 270w, it hits over 80 celsius.
I am skeptical PS5 gpu can run 2.23ghz constantly just on typical quiet air cooler.
