Those parts are also heavily binned. They only need to make tens of thousands of them. Not millions. The ones that don't pass that strict binning become 7850's. The ones that don't pass ps4 binning go in the trash. They can't afford to bin it like that. Not comparable.
Do you realize that the top end single card GPU TDPs have doubled since the Xbox 360 launch? Go compare a X1900 to a Titan or 7970. That's why consoles can't fit top end GPUs anymore, it's because the GPUs have ballooned to 200 to 250W by themselves. It's simply not possible.
Indeed.
They use an underclocked, partly disabled chip , that in its full ungimped form in a laptop uses 65watts of peak power, not 100+watts (let alone 200+watts as you love to imply)
They don't need to bin these parts for ps4 because they underclock them to begin with. (and disable 2 cus)
Your argument doesn't hold up at all since this gpu is not a 200 or even 150+W high end desktop gpu , that is the whole frigging point, and that is why it isn't impressive.
These baseless comparisons to geforce titans and gtx 580s etc are really annoying, it's the same useless argument that was made before we got the first spec leaks for ps4/xb-one for why we supposedly couldn't have anything equivalent to a gtx 580 in the console boxes.
Because people just went hurrrrrrrrrrrr gtx 580 300w chip durrrrr, ignoring that it's a high clocked 40nm based chip.
A low voltage low clockspeed 28nm smaller die gpu does not use much power, that's why it's used in laptops...
Anyhow, back to the original point: if they couldn't easily cool a <100W gpu and a low clocked laptop cpu (both frigging designed to be cooled inside a laptop shell at higher clocks) in a box that is 4x the volume then something would be very very wrong.
