The AMD Athlon 64 X2 3600+ was a desktop processor with 2 cores, launched in May 2005. It is part of the Athlon 64 X2 lineup, using the Manchester architecture with Socket 939. Athlon 64 X2 3600+ has 256 KB of L2 cache per core and operates at 2000 MHz. AMD is building the Athlon 64 X2 3600+ on a 90 nm production process using 154 million transistors. The multiplier is locked on Athlon 64 X2 3600+, which limits its overclocking capabilities.
With a TDP of 89 W, the Athlon 64 X2 3600+ consumes a good deal of power, so decent cooling is needed. 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.
