Do you think the PS4 and XB1 can be prejudiced for be based in a PC hardware?

[Squall]

Let's say that a console lives for 8 years.
During the first two years, an equivalent PC is way expensive and the game must be played on Ultra.
After two years, then buyable PC that can play games of the generation will appear.
During the last two years, the console version will be like the PC version on the Lowest settings.


PS4 has the new AMD accelerated processing units (APU) which is very efficient for graphics, because it has shared memory. It is superior to the PC architecture.

New important technologies are being developed for PC. They will make PC as efficient as consoles. In 2017, NVidia will release Pascal architecture and it will include the NVLink technology. It will make shared memory possible.
Mantle will make PC games more efficient too, because it will reduce the OS overhead.
