More information has been released on AMD's transition to 65nm process for developing their chips, as well as new technology support. Along with smaller frequency steppings for released processors, AMD is looking to include DDR2-800 support for all their 65nm CPUs, including the budget-class Sempron. Being that the memory controller is on the CPU with AMD processors, the CPU itself dictates what sort of memory it can support. It's good to see AMD pushing for higher class parts.
AMD is a bit slower off the starting block with 65nm, and we shouldn't expect these parts to hit the streets before the end of this year. However, AM2 boards are just beginning to emerge, and it's probably a good idea to let them mature. By the time December rolls around, DDR2-800 and an AM2 board should fit nicely together.
