Nordic Hardware claims AMD will introduce its first 45nm processors in the fourth quarter:
In the fourth quarter, AMD will unleash its two first 45nm processors in the form of two new Phenom X4 models based on the Deneb core, which will be followed by Propus-based CPUs in Q1 2009. Indicated by previous roadmaps, Propus lacks the shared L3 cache. AMD hopes to get retail Deneb up to 2.8GHz, while Propus models should land at 2.6GHz at best. Both of these are AM2+ (DDR2), but should be upgraded to AM3 and DDR3 in 2009.
The site also reports products with AMD's cheap ultramobile processors should be available in Q1 2009:
Beside the retail models, AMD is planning to unveil its cheap CPU targeted for ultramobiles we mentioned a few days ago. The CPU is based on a slightly stripped down version of the K8 core and is targeted for the fast growing ultramobile market. The advantages of AMD's processor is of course that the northbridge is more or less on-die, which results in an overall lower power consumption and simpler design than CPU plus chipset.
