PS3 MLAA, u don't want MSAA u want MLAA
http://www.eurogamer.net/articles/digitalfoundry-saboteur-aa-blog-entry

with MLAA the PS3 is actually beating the xbox360 EDRAM, and not by a small bit (look at god of war 3, and the future GT5)
they all use MLAA running on a single SPE.

intel/amd are only intrested in the final production cost, and gpu's are too expensive to produce long-term while simple cell like chips aren't.

the best example of the CPU future is in Ati's GPU where they since the 3000 series they just doubled the transistor count but kept the overall cost-equal to the previous chip.

also eventually with SPE's u could add spe's to spe's, u can make the old PPU's the new SPE's and adding new SPE's to the older PPU unit reducing bus-load.

just look at the price of the PS3, they are now running a profit on the hardware.
meaning the cost to produce the cell is also the future, as u could just add more and more spe's without adding to cost.

the x86 future is completely cell like, if they don't ARM will take over.

the advantage of smaller processing units is that u can disable them, which is ideal for a desktop/server device.

the multi-full-core model will cause a slow-down due to a saturated bus, and thus the future is in a cell-like platform where everything is managed, everything to get the best overall throughput at the lowest possible cost (also lowest energy cost)

this task-managing will be completely transparent like what IBM showed on the cell (which isn't ideal for gaming, and servers are more important than desktops)

I just read your article, thanks for the light indexed deferred rendering link.

I was a bit confused about what you were saying where if looking down a row of street lights that lots of the lights would occupy the same screen area.

I can understand this if you have to light translucent objects, but opaque objects would not be an issue.

Or perhaps you do not do a depth pre-pass? (or did not want to)

Was that the case?

re kyle:
not even close, the itanium doesn't have a multicore architecture (besides those with 2-4 cores) what it does have is multiple sub cores that can do like 3 or so instructions at once, but it can't use them in paralell.
In essence they tried to make the itanium faster by making it to execute large groups of instructions at once, something the newest intel processors solved in a simpler way by combining multiple instructions into a single instruction that is not part of the x86 set.
Either way this makes the itanium large and complicated, perhaps its good for some things, but for most it's better to keep it simple, i bet you can fit like 50 vector cores on the same space as a single itanium core and that has to count for something.

re Overlord:
Something like Itanium?
Imo, we are stuck with x86 forever ...
