Last week AMD confirmed that it would postpone the release of its Phenom 9700 and 9900 CPUs in order to focus on launching its triple-core Phenom processors in the first quarter of 2008, along with a low-power quad-core variant. Today, DigiTimes reports that it has managed to obtain the chips’ specifications along with those of three upcoming dual-core Athlon processors.

According to DigiTimes, the low-power quad-core Phenom 9100e is scheduled for release in February or March this year and will come with a core frequency of 1.8GHz, DDR2 1066 memory controller and TDP of 65W. In the second quarter, AMD will phase out the 9100e and replace it with a Phenom 9150e based on the TLB erratum-free B3 stepping.

In addition, the company will launch three dual-core low-power Athlon processors: a 2.5GHz Athlon 4850e, a 2.3GHz Athlon 4450e, and a 2.1GHz Athlon 4050e. All three chips will have 1MB of L2 cache and support for DDR2-800 memory.
