The AMD Athlon 64 3400+ was a mobile processor with 1 core, launched in April 2005. It is part of the Athlon 64 lineup, using the Newark architecture with Socket 754. Athlon 64 3400+ has 1 MB of L2 cache and operates at 2.2 GHz. AMD is making the Athlon 64 3400+ on a 130 nm production node using 105 million transistors. The multiplier is locked on Athlon 64 3400+, which limits its overclocking potential.
With a TDP of 83 W, the Athlon 64 3400+ consumes a good deal of power, so decent cooling is needed.
Neither SSE3 nor SSE4 instruction sets are supported, which will lead to problems with games not starting.
