SmallPops,

I did a quick comparison between the old XT3 and the new XT4. Seems like Cray starting using the new Rev F socket with DDR2 and decided that was enough to warrant the model number change. What a joke.

There is a little more to it. It incorporates ideas from Octigabay acquisition (XD1 line) into XT3. XD1 had a FPGA coprocessors incorporated in a custom way. The new line incorporates them in a more standard way, in direction of Torrenza, such as either having the coprocessor in an Opteron socket, or possibly on a board that would connect to their SeaStar interconnect (not quite sure about the 2nd part).
