I would call the difference between PS3 and PS4 just a bump in CPU/GPU there is a huge difference. The PS3 cpu architecture is completely different from the PS4. The PS3 uses a custom PowerPC architecture. The PS3 can be used to make super computers.
At the same time, gaming consoles were simplifying, making them less useful to science. The PlayStation 4 outsold both the original PlayStation and the Wii nearing the best-selling status currently held by the PS2. But for researchers, it was nearly useless. Like the slimmer version of the PlayStation 3 released before it, the PS4 can’t easily be turned into a cog for a supercomputing machine. “There’s nothing novel about the PlayStation 4, it’s just a regular old PC,” Khanna says. “We weren’t really motivated to do anything with the PlayStation 4.”
