PS3 has more powerful CPU than PS4 - 8th cell not even unlocked
Xbox One has more powerful CPU also than PS4 but PS4 doubles GPU power on Xbox One a
[QUOTE]The previous generation – Microsoft’s Xbox 360, and Sony’s Playstation 3 had very robust CPU’s. Naughty Dog (along with many other developers) have often highly praised the PS3′s SPU’s (Synergistic Processing Unit) as they were in effect vector processors Read more on the PS3′s cell processor here. They were in some ways a precursor to the Playstation 4′s GPGPU structure. So, the Jaguar’s lag behind, running the cloth simulation is too expensive.
You’ll notice the Playstation 4′s CPU performs slightly inferior if compared to the Xbox One’s; clearly this difference can be attributed to the raw clock speed difference between the two machines. Microsoft, as you might recall, bumped up the clock speed of their CPU (using the AMD Jaguar, in the same configuration as Sony, that is four cores per module, two modules total) from 1.6GHZ to 1.75GHZ. Sony didn’t do this, and despite tons of speculation as to the actual clock speed of the PS4′s CPU clock frequency, it was eventually confirmed by Sony to have been left at 1.6GHZ, thus providing Microsoft a slight advantage.
The CPU’s in both machines are relatively weak compared to their GPU’s, and thus offloading work load to the GPU’s remains the only logical choice. Ubisoft (like many other developers) are starting off loading a lot of work to the GPU. It’s high shader count allows for SIMD (Single Intruction Multi Data) nirvana. Quite simply put, multiple of the processors inside the systems GPU can be assigned to the task, and they’ll work at this task until it’s complete.[/QUOTE]
