We have all the clarifications we need.

So far, reviews show that all the AMD RX480 cards draw around 160W.

This settles the question how fast the Sony SoC will be. Even the rumoured/leaked 911MHz gpu clock probably is at the high end of what goes.

What is it with people these days? Now its power supply? smh

A discrete GPU recieving power is recieving power for eveerything in the GPU. Chip, memory and fan and any other electrical component in there. I mean memory alone can draw up to 20W!!!! And are you aware that even if the PS4 uses around 90-150W in total poeer right now its PSU is rated at 230-250W?

I don't think you really know what you are trying to say.

Let's take any RX480 5.5TF card. It draws over 160W to achieve this as per all the reviews we see. This wattage is drawn by the mosfets (7phases, apparently) that run the gpu and the 8G memory, and 1-2 fans.

Now move over to the Ps4 Neo. What do we have additionally here that needs power?

a) a motherboard with all interfaces (HDMI, SATA, USB2, IR, etc).

b) a cpu assembly (probably 6-8 cores Zen lite) needing its own mosfets (2-3 phases).

c) all the rest of the good stuff (something like a Soutthbridge/an arm processor with memory, a harddisk, a blu-ray drive, etc).

All this would bring you to way over 200W which is an absolute no-no for a console. You won't believe it but there actually are laws (at least in Europe) that regulate how much power a console is allowed to draw....

And if you are puzzled by the PS4's psu, a generic psu is best operated around 50-60% of its tpu rating, that is well known and you can see that in every data sheet of every generic psu. Unless it is an expensive psu tailor made for running at 90%+. You'll never find such a thing in a console.
