The PS4 Pro launches next month and it will be the most powerful games console on the market, with twice the graphical horsepower of the original PS4. But that comes with a steep price in energy consumption: the PS4 Pro consumes almost twice as much electricity as the updated PS4 “Slim”, despite having the same CPU, RAM, hard drive and other components.

The only upgrade is the GPU, which features twice as many cores as the regular PS4. But is that enough to explain the massive increase in power consumption that comes with the PS4 Pro?

The PS4 Pro is rated at 310W, while the updated smaller PS4 consumes just 165W. By comparison, the original PS4 consumes 240W.

Granted, the PS4 Pro is quite a bit more powerful: the graphics are 2.4x as powerful and the CPU has a slight increase in clock speed. But neither of those should double the power consumption. None of the other components have an increased power draw: the RAM is the same, the harddrive is the same, the motherboard is the same.

The real reason the PS4 Pro uses so much power: old process technology

There’s only one logical reason to the massive increase in Wattage: the updated PS4 “slim” has a CPU built on AMD’s new 16nm process, while the PS4 Pro’s chip is built on the old 28nm.

This would make sense as the PS4 Pro’s chip has been in development before AMD introduced its new 16nm process, and they simply didn’t have time to move the new chip to the new process and meet the launch date for November.

The old PS4 console used 240W of power and was built on the same 28nm process. The increase in power usage in the PS4 Pro compared to the old PS4 seems reasonable considering the new GPU.

Which means that those who purchase the new PS4 Pro this Fall won’t be getting the latest and greatest technology, at least when it comes to efficiency. It also means the console will be quite hot compared to the other two versions.

We’re sure that in the future, Sony will update the PS4 Pro once AMD can make the CPU/GPU in 16nm. But if you’re planing to buy one this Fall, get ready for an increased electricity bill if you game as much as we do.
