REAL -TIME raytracing was never done before......RAYCASTING was done.
CELL is 1000x more powerful than conventional pc cores.IF u havent looked at CELL benchmarks i could provide you with 100s of link.
you wd need atleast 50 quad cores to do that.
CELL on average is around 23x more powerful than a quad core amd/intel.

NOTE :- with a mdified octopiler,EDGE and irt the performance boost could exceed 1000 in all case.

Here's a fresh demo of my Arauna raytracer:
http://www.bik5.com/arauna_demo2.zip
Instructions:
1. Unzip and run arauna_supersampling.exe to measure peak performance (~11M on my machine);
2. Open scene.txt and add '//' to the fifth line (speedtest);
3. Run arauna.exe to walk around the scene. Keys:
A, S, D, W to walk forward/backward and strafe;
cursor keys to rotate the camera;
R and F to move down and up (reversed, sorry, forgot to fix).
That's the basic stuff; there's more to try out using scene.txt, have a look at the file to see what's possible.
washimul do you ever know what you're talking about?
Edit: BTW, that demo runs on my Athlon 64 X2 3800+ and is far more complex than the demo I saw running on a Pentium 3 ...
If the Cell really was 1,000 times as powerful as conventional CPUs we should be seeing Resistance: Fall of Man being raytraced ...
the Aurana demo runs at 1 fps ......u are comparing that to CELL...............what a shame.
did you read the links i provided????
atleast know something before posting.
This is what Barry said regarding raytacing
http://gametomorrow.com/blog/index.php/2007/03/07/cell-power-at-gdc-2007/To put this render job in perspective I just ran one frame of this scene through 3dsMax’s default ray-tracer an it took my Centrino Duo (dual core x86) machine one hour eight minutes to render what Cell and the iRT renders in less than one half of a second.
do u get an idea of how powerful the CELL is :
1 hour 8 minutes on DUAL CORE CENTRINO translates to just half a second on CELL
MODS :- i just posted valid links and still u have people arguing unnecessarily.
SQUIRREL..........u wd be seeing full fledged RAYTRACING in ps3 games by the end of JUNE..............fingers crossed
