So basically a PS4 with FX-4150, 4GB GDDR5 + 32MB eDRAM, R9 280x. Uses AMD's answer to a i3-4150 yet still has games doing 1080p60 90% of the time.
The PS4 illustrates the essence of this thread: "How can we offer a more powerful console than the PS4 while costing less?" An all-digital console with 6GB of RAM would allow for a gpu more powerful than the 1.84tf. However, a 1.34tf gpu can also handle 1080p games.
What decision would you make? (think like a manager)
A - 6GB, all-digital, 2.56tf, and a sub-Jaguar cpu, to run PS4 like games in 1440p30fps
$399
remember, 1440p TVs didn't exist in 2013, and the internet was very limited,
a strong marketing campaign would also be needed to encourage console gamers to use DisplayPort monitors
since it only has 6GB and a sub-Jaguar cpu, in some games the PS4 would be able to obtain superior or equal quality.
B - 12GB, Xbox One gpu, sub-Jaguar cpu, no storage like Wii U but many exclusive games in 1080p, such as Forza Horizon 5 and Gears 4, they ran on the Xbox One despite the weak gpu
$349
with no multiplatform games in the first 2 years it would be possible to claim the existence of some secret sauce , a lie but no one would be able to prove otherwise.
