AMD will unveil new Sempron, Athlon 64 and Athlon 64 X2 processors with reduced power consumption. There will be two Socket AM2 processors for SFF systems with a 35W and 65W TDP.
The initial family AMD Sempron with 35W TDP will include models 3400+, 3200+ and 3000+, but by Q4 the company is expected to add model 3500+ as well. AMD will not put a lot of effort into creating a lineup of energy efficient single-core Athlon 64 chips: there will be only one model available: 3500+ with 35W thermal guideline, which will be supplied for quite a while. All Sempron processors today have 62W TDP, whereas the Athlon 64 3500+ may have thermal guideline of either 67W or 89W, depending on the stepping. Typical single-core chips for future socket AM2 platforms will have 62W thermal envelope.But AMD's new high-end Athlon 64 FX-62 will have an expected power consumption of 125W, whereas the Extreme Edition of Intel's Conroe will only use 95W.

The Energy Efficient family of dual-core Athlon 64 X2 processors will include Athlon 64 X2 3800+ with 35W TDP, which will remain single dual-core offering with such a low power consumption till Q2 2007, as well as models 3800+, 4000+, 4200+, 4400+ and 4600+ with thermal guideline of 65W. In Q3 2006 AMD is expected to introduce the model 4800+, which is expected to remain the top energy efficient offering till the Q2 2007, with similar thermal specs. Depending on the speed bin, the dual-core desktop chips from AMD now have 110W or 89W TDP. Typical dual-core chips for socket AM2 will have TDP of 89W.
