The AMD Athlon 64 2800+ was a desktop processor with 1 core, launched in April 2004. It is part of the Athlon 64 lineup, using the NewCastle architecture with Socket 754. Athlon 64 2800+ has 512 KB of L2 cache and operates at 1800 MHz. AMD is building the Athlon 64 2800+ on a 130 nm production process using 69 million transistors. The multiplier is locked on Athlon 64 2800+, which limits its overclocking capabilities. With a TDP of 89 W, the Athlon 64 2800+ 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.
