AMD has just released their latest quad-core speed-bump in order to give consumers the option for a little more bang and a little more buck. With the release of the AMD Phenom II X4 975 'Black Edition' processor, AMD has added a new king to their Phenom II X4 quad-core product line. The previous leader in this category was the Phenom II X4 970 at 3.5GHz and 125W TDP. The 975 adds 100MHz for a total of 3.6GHz. This clock speed not only marks the highest quad core, but the highest base factory clock chip in all of AMD's desktop processor lines.  With a price-point of $195, AMD also maintains their sub-$200 barrier in their quad-core processors.
