It's also strange that this only mentions an upgraded GPU. You'd need more than just a GPU upgrade to hit 4K, PS4 CPU is kind of on the weak side. Pretty sure you'd need at least 4 more GB of RAM as well.

Isn't the RAM inside the GPU?

No, the RAM are seperate chips on the motherboard. However the CPU and GPU are combined into one APU chip.
