HD 7970 Mobile tdp you mentioned not even counted with CPU factor that include with it (PS4 is an APU,  so the tdp are a combination of GPU+CPU) , also please give me the source for this claim. And also factoring the price i don't even see an equal to PS4 apu when it came out in 2013 .

75W TDP. - That's thermal dissipation not power consumption though.

In notebooks you are looking at a total TDP of 135W once you include all other components.

But total power consumption was around 80w~ including all other components including the display.

Not bad, not only does it use less power than the Playstation 4, it also offered substantially better CPU performance, better GPU performance and had more Ram, faster storage (SSD).

You don't need an APU to beat the chip in the PS4.

Did I mention it's also portable?

The reason why it need to be APU is for cost and latency, also many physicist job that should be done on CPU in PS3/Xbox 360 are now done on GPU with HSA and other methods , So yes cost is a factor in building consoles.
