We have to admit to being a little surprised a few weeks ago when AMD emailed us to say our review sample of the new high-end Athlon CPU was on its way. 2006 was the last time we had such an email and since then the Phenom line of processors has been AMDs focus, with a limited number of Sempron models released into the budget marketplace. The model we are testing today is the 7750 Black Edition, quite a jump from the current highest model, the 6400+.
