New demo
Saturday, February 28, 2009 | Permalink
It's been a while, but I have finally added another demo to my site. Yay!
Those of you wishing for some pretty eyecandy will be disappointed though. This demo features green spheres.
But it's pretty cool though if you're into shader programming. It shows how to emulate a stack and recursive functions in a shader in DX10.

It has been rumored that the PS4 won't have separate GPU/CPU chips, just like how the PS3 where meant to work before they added the RSX chip (the design originally called for at least 4 cell chips working in parallel and at maximum speed, but that proved to be too expensive).
So yea, the CPU is doomed in it's current form.

Sony seems to be going in the opposite direction though, having the CPU do all the work. Wouldn't it be prudent to have focused more heavily on a really advanced gpu doing all the work than four+ processors with a bunch of cores?

Yea, but cell is more like a GPU, each SPU is definitely way more powerful than a processor element in the gpu, it has at least 3 times higher clock speeds (in the case of the original PS3 5 times) and can do a lot of more work per clock.
so 4cells*8cores*3-5times the speed=96-160gpu core equivalent, and that's pretty close to the last gen of graphics chips.
But on the other hand GPUs are moving more towards the the generality of what CPUs can do, so somewhere these will intersect, i think this is the path the ps4 will take.
