This is the first time that a single system has owned all four categories. The new System p 570 now holds 25 benchmark records across a broad portfolio of business and technical applications (5)."
And before I go on: Click source link, read, click more links.
A record in some absolute number which says nothing about being efficient, and a link to IBM themselves.
The colorful bars is what I read, if you compare the 4.7GHz things to the 2.2 Power5+ I would say it isn't very efficient compared to its older brother. 60% faster, over twice the clockspeed. The Xeons in the list are MP's, which means they are memory starved Netburst processors. In a few months we have Tigerton which will come a lot closer to the Power6 but is a lot cheaper. I'm not impressed by the Power6.
