This summer AMD will launch a new lineup of Energy Efficient processors. The CPUs will arrive as early as in June or July, coincident with the launch of Intel's Conroe.
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.
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.
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. More details over at X-bit Labs
