The AMD Agena and Kuma processors should start sampling next month. The first versions of the Agena FX processor that will reach retail stores are the 2.6GHz and 2.8GHz ones.
The Agena FX will be available in both for socket AM2+ and 1207+, although you'll have to make do with the 2.6GHz version if you don't want to use socket 1207+. This CPU will also be limited to single processor systems, as the AM2+ socket doesn't support multi CPU configurations.
The standard Agena range will initially be available at 2.4 and 2.2GHz, while the entry level Kuma processor will clocked at 2.5GHz.
These are the dates for sampling, mass production will take a couple of months longer.
