here is information about the bottleneck.

in essence, everything with higher bus speeds such as RAM are communicating directly with the controller, not the G4. DDR memory costs more for the PowerMac with absolutely no benefits.
Apple does this because people think, ooooooh! DDR, oooooooooh! faster Macs!
...a Dual Mac > 1GHz with SDRAM? Hmmmmm... Nowhere! You only saw a Dual 1GHz running a single app at a time at barefeats or anywhere for that matter and you decide to spread the word that indeed a DDR Dual is slower than SDRAM, eh?
Excuse me, but under heavy conditions the DDR (including the 1GHz Dual) Macs fare MUCH better than the previous SDRAM models... But hey: What Apple knows and exchanged the SDRAM with DDR? It costs more hah? And how come they keep pushing their prices down?

And let the people who actually used the new DDR Duals to decide if their Macs are fast or not! As for DDR, in case you CANNOT get it, let me put this way: With this new underlying technology not only the Macs are able to perform MUCH better than the previous SDRAM ones but also lets them scale upwards better... Even on the Wintels, DDR lets them use more busses, more peripherals, more stuff at the same time... If one doesn't understand something, he should check things first THEN decide! And I know for 100% that most people here that iWhine about PowerMacs NEVER used the high-end Duals cause if they actually used them, they should know this:
-NOTHING CAN TOUCH THEM UNDER HEAVY LOAD IN THIS PRICE RANGE OR BELOW
And this comes from a guy who can back things he says IF and WHEN that forces that be around here will let him post a video or two just to clear things out because charts and stuff are nice but Audio & Video rules
Slow Duals I read you say? Never truly you used ones I get... At least I did use and always continue to do so because Dark Side has nothing over me
