Actually, the after spending some more time with the article, it appears that the Cell power CAN NOT be realized, because fully 100% of that article is working around functions of the Cell because they are inefficient. In other words, they're telling you how to 'skip' parts of the chip that should do something but won't, or not very well .http://www.ibm.com/developerworks/power/library/pa-celltips1/
This shows that the cells power hasn't even been FULLY utilized... iamthetruth55
[QUOTE="br0kenrabbit"]The Cell can't branch for crap. 18-19 missed cycles for a wrong prediction? Holy crap! So instead of having nice, neat and compact branching code, it's gotta be done the long-way around per statement. No wonder PS3 games take so long to make.thegoldenpoo
i have no idea what you just said, seriously.
The short of it: The Cell isn't very efficient.[QUOTE="br0kenrabbit"]The Cell can't branch for crap. 18-19 missed cycles for a wrong prediction? Holy crap!

You seem to know your coding and processors. what i have to say to that is The developers were lazy in the beginning and didn't know what to do with the cell's complex power. Now that they have a guideline to figure it out the games will come rolling off the shelves. I'm excited for what could be at store for such a powerhouse as SONY.
It's just funny that Sony and IBM go so far out of the way to make a processor with all these little nooks and crannies that they claim will give it an edge, and then in their own white papers suggest working around these very same nooks and crannies to better performance. But then again, weren't we suppose to be using the Emotion Engine in everything from TVs, Cell Phones to Shoes by now? And wasn't 'The Cell' suppose to follow suit? Yeah, not going to happen. The Cell was a good idea on paper that just doesn't work the same way in practice. Not saying it's a bad chip, it's just not performing as it was hyped to, and it's 'special architecture' in some cases, as above, seems to work against it.
