This has always fascinated me. Sony spout out every time they opened there mouths, but there was a large group of techies who pulled apart the specs and came up with this analysis:

Make sure to read every page. If you're too lazy, the article goes on to prove that the 200 gigaflops of processing power at 100% efficiency Sony say the Ps3 can pull is BS. During testing, a maximum of 75% efficiency was achieved, which severly limits the numbers. Then they announced on 6 of 8 spu's are for gaming, so thats another 25% reduction in power. Real figures end up being closer to 80 gigaflops. Furthermore the 360 uses less system ram for the OS, reads information faster from a disk than the ps3 does with blu-ray and the graphics chip in the 360 makes the Ps3's graphics chip look like a voodoo2 by comparison. The whole article is an excellent read for anyone interested in the truth about the power figures. Feel free to spread the link around a few other forums, get the word out to stop the lies from Sony. A $100 price cut is nothing if there is a more powerful console which is cheaper with better online gaming and more games to play. Wii60 FTW!
