The AMD Athlon 64 3400+ was a desktop processor with 1 core, launched in January 2004. It is part of the Athlon 64 lineup, using the ClawHammer 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 89 W, the Athlon 64 3400+ consumes a good deal of power, so decent cooling is needed. AMD's processor supports DDR1 memory with a single-channel interface. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability.
Neither SSE3 nor SSE4 instruction sets are supported, which will lead to problems with games not starting.
