Actually it does the job better than GPU sometimes with floating point calculations. It really depends on application. Anyway for raster rendering its kind of useless and thats what GPU usually do only.

Several reasons spring to mind

1) The PC has mandatory install for all games, the PS3 only has it for their most graphically challenging ones

2) RAM - the PS3 has 256 mb of mian ram, and a video card with 256 mb of dedicated Ram - most computers have multiple times this. My friend just assembled a gaming rig with 4 GB ram and a 512 mb video card

3) As everyone has said, 7 cores is not useful for gaming, and developers are much more practiced at getting the best out of PCs

Or was that rhetorical?

Certainly not the raw throughput. I've been reading up on the compute shader in the Direct 3d SDK and its looking pretty cool. By the time the PS4 is out we'll probably be looking at the draft spec if not the final result for direct 3d 12. I Was more talking about the future since the software to take advantage of the Cells unique abilities hasn't been written either.

Well, it is shown that CELL can do nicely raytracing when compared to regular CPU or GPU,

(GPU architecture just isn't made for raytracing. :P)

Anyway, theres no really need for raytracing or extra power for floating point operations in todays games so it really doesn't matter from game point of view.

I predict that MikeB will show up soon and start pasting things he doesn't really understand himself.

And ray-tracing isn't made for real time!

First idea was to use Cell for graphics. Sony realize that they overestimate Cell power too late. They have no time and rush to nVidia for GPU. They choose the one that was better then "official 360 GPU specification". If you remember after PS3 came out ATI announce that Xenos is actually better then RSX, but MS lower Xenos specifications to mislead SONY.

I remembered seeing a demo a few months back of a real-time raytracing demo using the CBE. A quick Google search yields all kinds of info on real-time raytracing using the PS3 by developers/programmers.

So, the CBE is not the problem for the PS3. The issue is mainly memory (lack of) and reliance upon GPUs that simply age too quickly to stay on the edge of graphical development.

The RSX is the rough equivalent of a Nvidia G70/7800 GPU commonly used in high end gaming PCs back in 2006. Emphasis: back in 2006. Most of the cards based upon that GPU only shipped with 256MB of VRAM as well.

You'd be hard pressed to find a single serious gamer using a G70 based graphical solution unless they were using an old laptop, or were too poor to afford a cheap G94 or G92 based VGA card for even a $100. Most serious gamers have already moved forward two generations to an R770/4000 series ATI GPU or a GTX200 series Nvidia GPU(s).

So the point is pretty much as an end user, most non-tech savvy individuals are not going to see the merits of the CBE as a developing technology.

The gullible will buy it simply from being overly succeptible to marketing claims and the ability to boast about having something they don't even fully understand.

    So that kinda proves that Killzone 2 can be handled by Xbox 360 as well, since only 5 processors are utilized and the last 2 processors are mostly idle, besides 360 has 3 general cores, each of which is easier to program for and utilize. It is also a much cheaper and more efficient solution.

No, it wouldn't have the same effects as a version running with CBE assisted physics.

You can speculate all you'd like, but the issue is pretty much moot anyway since it's not going to be released on the 360.

When we see a 360 game that uses the same level of effects running on a title, only then could such a claim be made.

Totally non-related, but the other game PS3 fans who like to claim could not run on the 360, even if storage wasn't an issue (MGS4): it not only can, but it does - it's just not going to be released (yet).

well he was made to be teh perfect warriior once he ate a couple of androids then he was going to destroy teh world ...not a real point other then for the z fighters to battle with
