I thought this was supposed to be a stage demo, not a replay of the same video they showed off in the conference.

@Auction_Sniper While this is true, remember that the PS3's system RAM is clocked at 3.2 GHz. At that time, even the best desktop RAM cards were 1/3 that speed. So essentially, what you don't have in memory space you make up for in bus speed, as you can access the data much faster. By 2006 standards, it's not as underpowered as you might think.
