Intel Penryn CPUs are not available yet, that information about the future CPU generation is already spreading on the web. The Nehalem will be engraved at 45nm and should be available during H2 2008. It will be true native Quad Core CPUs and not dual Dual Core CPU as today for Xeon Penryn. It will also be the first Intel CPU to integrate the memory controller into the chips to boost performance and even further increase the cache size.
the good news is that beside the increased number of transistor, the TDP should be around 130W for the non-Extreme version of Nehalem.
To further decrease the TDP, one will have to wait for 2009, when Intel will transfer engraving technology to 32nm, but at that time clock speed might have increased, and Intel will most likely offer dual Quad Core CPUs
