Q2 2010 BY 10th of May AMD Thurban X6 1075 2.8Ghz, 2.4HT, L2 2Mb, L3 6Mb, TDP 125 = Bios update for AMD2+, AMD3 motherboards,
Q1 2010 AMD Deneb X4 975 3.6Ghz, L2 2Mb, L3 6Mb TDP 125 - 140 = AMD does not want to compete itself e.g X4 965 140 TDP - X4 965 125 TDP. Originally X6 1075 was a 140 TDP part and now is 125 TDP. The 125 TDP parts have much grater exposure and market share than 140 TDP parts. Expect AMD CPU'S Phenom 2 X2, X3 and X4 to reach 4 Ghz by the end of 2010 - Q1 2011.
The X2 CPU's technically can already be produced at 4.0 Ghz TDP 140.
e.g X2 555 3.2 GHZ 80 TDP, 565 3.4 GHZ 95 TDP, 575 3.6 GHZ 110 TDP,
585 3.8 GHZ 125 TDP and 595 4.0 GHZ 140 TDP. The technical abilities of AMD Phenom 2 X3 and X4 allow it to be produced at 3.6Ghz 140 TDP.
AMD will hold the fort with Denebs X2, X3, X4 and X6 untill Q1 2011 Bulldozer and Bobcat AM3r2 = AM3+
AMD X2, X3 and X4 are the same Deneb core with disabled cores for X3 and X4 ;-D.
