Though most powerful capabilities of latest Windows Server 2012 release to my mind are related with its accomplished feature set and new usage scenarios I should admit that we people like to look at numeric metrics and increased figures. Incidentally, some of new things/scenarios available in Windows Server 2012 wouldn’t have been possible without significant scaling up of possible workloads and used resources. So you may find comparative table of scaling for nodes and workloads for WS2008R2 & WS2012RC below (sorry if you are cyrillically challenged, but only Russian version of table was available at my disposal).
