The AMD Athlon 64 3400+ was a desktop processor with 1 core, launched in April 2005. It is part of the Athlon 64 lineup, using the Venice architecture with Socket 939. Athlon 64 3400+ has 512 KB of L2 cache and operates at 2.2 GHz. AMD is building the Athlon 64 3400+ on a 90 nm production process using 69 million transistors. The multiplier is locked on Athlon 64 3400+, which limits its overclocking capabilities.
With a TDP of 67 W, the Athlon 64 3400+ consumes typical power levels for a modern PC. AMD's processor supports DDR1 memory with a dual-channel interface. The highest officially supported memory speed is 400 MT/s, but with overclocking (and the right memory modules) you can go even higher. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability.
The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability.
