The AMD Athlon 64 3500+ was a desktop processor with 1 core, launched in June 2004, at an MSRP of $500. It is part of the Athlon 64 lineup, using the ClawHammer architecture with Socket 939. Athlon 64 3500+ has 512 KB of L2 cache and operates at 2.2 GHz. AMD is making the Athlon 64 3500+ on a 130 nm production node using 106 million transistors. The multiplier is locked on Athlon 64 3500+, which limits its overclocking potential.
With a TDP of 89 W, the Athlon 64 3500+ 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.
Neither SSE3 nor SSE4 instruction sets are supported, which will lead to problems with games not starting.
