After working out the equation, they can both support the exact same 1280x720 @60x2 for all color depths (I was almost sure before doing the actual math that 32bit would be to much bandw for HDMI 1.2, but it isnt...barely)

1280x720 (pixels) x 60 (fps) x 2 (both eyes) x 32bit (color) = 3,538,944,000 gigabites/s  (HDMI 1.2 can support 3.95gigabites/s)

Just to be complete: 

1920x1080 (pixels) x 24 (fps) x 2 (both eyes) x 32bit (color) = 3,185,049,600 gigabites/s (HDMI 1.2 COULD support this...atleast it has the bandw to do so)  

1920x1080 (pixels) x 60 (fps) x 2 (both eyes) x 32bit (color) = 7,962,624,000 gigabites/s (HDMI 1.2 COULD not support this...but neither do todays supposed 1.4a HDMI tvs.... tho they do have the bandw)

1920x1080 (pixels) x 60 (fps) x 1 (regular 2D) x 32bit (color) = 3,981,312,000 gigabites/s (HDMI 1.2 COULD not support this, probably why most 1080p games are 24bit anyway)

1080@60x 32bit 2D > 720@60x 32bit 3D.  Interesting isnt it?


Damn, well put.

Yeah I figured that 1080p @ 60 is greater than 2X 720p @ 60 as 720p isn't an accurate half of 1080p.

I think that if you took 1360X768 resolution X 2...that should be as close to 1 X 1080p as humanly possible (while keeping the same aspect ratio. Hence why I think a lot of HDTVs have that as their resolution, over true 720p.


Almost makes you wonder if they did this on purpose (limiting 3D gaming to 720p, as that is as high as 1.2 can support)..... it cannot be that simple can it?  

Sony has almost NOTHING to do with HDMI 1.4a specs (they are part of the council but not enough to control it by any means).  Since the PS3 has the bandwidth to do  2 x 1080@60 at 32bit, but NOT the processing power (lets be honest here, no way in hell it is doing a real game at this level with 32bit color), you think it is possible they did this on purpose?  Why go higher when you A) cannot handle it, and B) more adopters because of the 1.2spec on the 360.

CONSPIRACY! hehe (EDIT)  

and here ya go :)

1360 x 768 x 2 x 60 x 32bit color = 4,010,803,200 (barely over 1.2 HDMI bandwidth) tho it would obviously work at any color depth below 32bit.

 

PS: math is good :)
