Stan85's question regards the second "chart". |
First one... PPE only is about 0.4*X360. (+SPUs = ?)
And memory bandwidth... Eww... It has very very fast eDRAM being as a very big 'cache', but both GPU & CPU(on X360) are stuck with about the same bandwidth as RSX(GPUs own memory only). And adding together RAM&eDRAM and also adding together CELL&RSX bandwidth like in that picture. *facepalm*
Heres what it looks like:
You can get stuff from ram, but you must do it through GPU everytime. So CPU & GPU 'can't' really access memory at the same time.(You can always get 'all' you need to eDRAM.) And what makes it fast? You can put stuff into eDRAM and do just about all you need in there. Its more than 10 times faster than regular ram and you can access it much faster. That means smaller delays when playing with data. (On parallel computing course I attended it was about 100 cycles to get something from ram in todays comps. When you do that a lot it will be a lot of cycles. Anyway... :) )
And for as a bonus what does PS3 bandwidth chart look like:
Hopefully this was also an answer for Stan85's question...
I like new toys too, but I usually don't like to be forced to use new tools for work. ;P
(Anyway I would love to play around with PS3(Programming mainly, I don't like those games, way too simple for me. :P), but the price is way too salty right now. I might get it later however. X360 meh... it doesn't offer anything new.)
