Today we will be looking at one of AMD's latest weapon in winning back the faithful who had lost their way and have been debating stepping into Intel's camp. The weapon that we are referring to is the bug fixed X4; or to be more precise the 2.4ghz 9750 X4 in its B3 revision. In this review we are going to put the X4 through its paces, both in Windows XP and Vista to see what this new processor is made of and compare it against the venerable Q6600.
