AMD's newest roadmap reveals many more Phenom processors for 2008, but tops off at 2.6 GHz

AMD's latest corporate guidance reveals a flurry of changes to the company's line of desktop processors. Most importantly, the new roadmaps indicate the arrival of AMD's higher-end Phenom processors.

AMD's first update to its performance segment will take place later in Q2 2008; the company will unveil two new Phenom processors: the AMD Phenom 9750 and the Phenom 9850. The Phenom 9850 features a 125 Watt thermal envelope and runs at 2.5 GHz, while the Phenom 9750 runs at 2.4 GHz and features a 125 Watt TDP. Around this time another configuration of the Phenom 9750 will be released, but this processor will feature a lower 95W TDP. 

In Q3 2008 AMD will release its AMD Phenom 9950 clocked at 2.6 GHz.  The Phenom 9950 is one of AMD's last high-end 65nm chips and features 140W TDP, the highest of any Phenom processor. Roadmaps indicate that there will be another processor released after the AMD Phenom 9950 though this is likely a lower TDP version of the same frequency. 

Next month AMD plans to launch two new chips for its upper mainstream market, the AMD Phenom 9550 and Phenom 9650. AMD guidance says the 9650 runs at 2.3GHz, whereas the 9550 runs at a slightly lower 2.2 GHz.

Halfway through Q2 2008 the company will release three more Toliman triple-core processors for its lower-mainstream segment: the AMD Phenom 8450, Phenom 8650 and Phenom 8750. They feature an operating frequency of 2.1GHz, 2.3GHz and 2.4GHz, respectively. All three chips feature a 95W TDP.

AMD guidance suggests all of these processors are based on the B3 stepping.  There are no more scheduled revisions to the 65nm architecture. 

AMD finally makes the jump to 45nm halfway into Q4 2008 with its Deneb and Propus-based chips.  Both feature quad-core architectures and 2MB of L2 cache. However, the major difference between the two is that Deneb features an L3 cache pool shared amongst the processor cores, Propus does not. Deneb will be targeted at AMD's performance segment, while Propus will be for AMD's mainstream chips.

Both of these 45nm processors are described as 95W TDP processors. 

As indicated in December, the company will not announce DDR3 support with the initial Deneb and Propus processors.  The initial 45nm Phenom processors will stick with DDR2-1066 until early 2009, where another revision will include DDR3 support.
