Reducing security risks from open source software

Review The first two models of AMD’s Phenom II processor showed that the move from 65nm to 45nm was thoroughly good news. It reduced power draw and waste heat while allowing AMD to increase clock speeds, which is very jubbly indeed.

Now it’s time for the other half of the story, as AMD unveils Socket AM3 with its support for 1333MHz DDR3 system memory.

AMD's Phenom II: now with DDR 3 support

AMD has launched five new models of Socket AM3 Phenom II, with three models in both retail and tray packaging, and two models that are only available in trays for system builders. The retail parts are:

  • AMD Phenom II X4 810 (2.6GHz, quad core, 4MB L3)
    Available in PIB at AMD's suggested 1KU price of $175 each (£160 retail)
  • AMD Phenom II X3 720 Black Edition (2.8GHz, triple core, 6MB L3)
    Available in PIB at AMD's suggested 1KU price of $145 each (£131 retail)
  • AMD Phenom II X3 710 (2.6GHz, triple core, 6MB L3)
    Available in PIB at AMD's suggested 1KU price of $125 each (£113 retail)

While the two tray parts are:

  • AMD Phenom II X4 910 (2.6GHz, quad core, 6MB L3)
  • AMD Phenom II X4 805 (2.5GHz, quad core, 4MB L3)

Because these are tray parts we do not have prices. But here are AMD's official specs for the parts:
