Dont know how creditable this is, but the guy seems to know wtf hes talking about. He does a preety damn good job explaining the little details. The conclusion made me laugh.

I find it amazing that by 2020 first world countries will be competing to get immigrants.
I think everyone here knows how to copy and paste.
EDIT: Seems like he knows what he is talking about, but I don't understand half of that
For example the guy goes off that the SpE has no branch predictor... thats because it uses branch hinting instead..
or the guy says the SPE's have no cache... but he doesn't tell you that they each have separate registers...
And the SPE's DO have access to system RAM...
Also the guy equates the RSX to the Nvidia 6800 which is laughable... since its pretty widely accepted that RSX is comporable to the 7800...
The Guy also throws some retarded statistics in there like "Sony's CPU is ideal for an environment where 12.5% of the work is general-purpose computing and 87.5% of the work is DSP calculations"
LOL WTF where the hell did he pull those stats from? I always follow the rule of thumb that 80% of statistics are made up.
Also the specifics of RSX haven't even been released...
Guy also says that multithreading for the PS3 is hard.. but he doesn't touch on the multithreading difficulty on the Xbox360.. take this for example ... The PS3 can handle 8 threads simultaneously.. while the Xbox360 can handle 6... he says PS3 is at a disadvantage because of this ... but Xbox360 is strangley absent...
I would take this article with a LARGE chunk of salt...

Man, you never give up Spath. That article is a word for word copy of a Major nelson blog posted in 2005.
And, a "blog posted in 2005"? In 2005 the technical information on the PS3 was still behind closed doors, so these claims, be it by you or this major nelson person, hold no water.

Major Nelson is one of the spokesmen for the Xbox360... he blogs tonnes of xbox information and gamers tend to go there for the juicy xbox info first... And after that dude said that .. i went and looked... and I actually found it...
Here
Part1
Part2 <- your article starts here
Part3
Part4
The article you linked seems to be almost word for word identical to the Major Nelson article... and this was done in May 2005... which gives me more proof that they had no idea what they were talking about..
por ejemplo
your link:
"CPU
The Xbox 360 processor was designed to give game developers the power that they actually need, in an easy to use form. The Cell processor has impressive streaming floating-point power that is of limited use for games."
Major Nelson's article:

Sony's CPU is ideal for an environment where 12.5% of the work is general-purpose computing and 87.5% of the work is DSP calculations. That sort of mix makes sense for video playback or networked waveform analysis, but not for games. In fact, when analyzing real games one finds almost the opposite distribution of general purpose computing and DSP calculation requirements.

GPU
Even ignoring the bandwidth limitations the PS3's GPU is not as powerful as the Xbox 360's GPU.
Below are the specs from Sony's press release regarding the PS3's GPU.
RSX GPU
550 MHz
Independent vertex/pixel shaders
51 billion dot products per second (total system performance)
300M transistors
136 "shader operations" per clock
The interesting ALU performance numbers are 51 billion dot products per second (total system performance), 300M transistors, and more than twice as powerful as the 6800 Ultra.

I actually think its quite sad that that blogger actually reposted a story from 2005 under his own name and a year later under the guise of new info.. hopefully now you can disregard the whole thing with that chunk of salt i told you to use earlier..GPU

And for the dude that pointed out the majornelson post... good catch.. although it seemed really strange since you never post....

Regardless, this is the only time I will find myself defending the PS3; the origin of the article dates to 2005, which is evidence that it is bullshit. Nobody outside of Sony would know that information, and even then it was a LOOONG shot considering the damn thing wasnt anywhere near being completed.

Given your past fanboy bias of the ps3, I'll take your post with a large chunk of salt as well
good day sir
Your argument is like a two legged dog with an eating disorder...weak and unbalanced.
I guess i'm the spice in your life
