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.
