Talk about vapor....
It is vapor, but it had a purpose. The announcement was that the quad core parts would be platform compatible, meaning customers considering dual core Opteron today have an easy upgrade in 2007. It makes sense for AMD to brag about this before launching as it affects their customer appeal.
Advanced Micro Devices is promising that no platform change will be required to move to its next-generation quad-core processors. And to prove it, AMD plans to demonstrate the technology in the middle of this year.
