I remember people using PS3 as compute cluster [1] some time ago. Is this still possible with PS5? My general question is: are there and what are some non-gaming purposes of jailbroken PS5?
If I remember correctly, the PS3's CPU is uniquely suited to the kind of work people use clusters for. It provided a halfway point between CPU and GPGPU, and at a price point which couldn't be beaten.
The PS5, on the other hand, basically uses medium-range off-the-shelf computer components. Its most powerful feature is the extremely fast SSD, but that is not very useful for a compute cluster. Nowadays anyone wanting a compute cluster would just fill a server rack with GPUs and be done with it.
The PS3 had a unique CPU design that made it suitable for certain specialized tasks. The PS5 is much closer to an off-the-shelf gaming PC, and so I don't think there's any good reasons to use a PS5 in that way, especially since PS5s are difficult to even buy in the first place.
