AMD wants to finish up with the DDR-only 939 CPUs. They will probably be sloshing around in the channel for a bit longer but the plan is to kill them for New Year's Eve. Socket 754 will get to live one more quarter and after that it will start to fade our as well. It's already had its death sentence.
In Q3 2006, Socket 939 and 754 amounted to sixty percent of all CPUs shipped and by the end of Q4. Now socket 939 CPUs are set to disappear and the 754 parts will drop to less then a 10 percent of whole CPU shipment.
AM2 is the socket to stick with. By the end of Q1, it will be dominant, with more than 90 percent of overall CPUs using that socket's revision F and five per cent of the rest will go to Quad FX socket 1207. Socket AM2 supports AMD virtualisation and of course all accepted DDR2.
The new AM2 revision G CPUs are the same AM2 CPUs with DDR 2 support but built of 65 nanometre SOI design. They are planned for this year's release so there's less than five weeks to go. µ
