The AMD Athlon 650 was a desktop processor with 1 core, launched in June 2000. It is part of the Athlon Model 4 lineup, using the Thunderbird architecture with Socket A. Athlon 650 has 256 KB of L2 cache and operates at 650 MHz. AMD is building the Athlon 650 on a 180 nm production process using 37 million transistors. The multiplier is locked on Athlon 650, which limits its overclocking capabilities.
With a TDP of 38 W, the Athlon 650 consumes only little energy. AMD's processor supports DDR1 memory. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability.
A lot of games will not work on this processor, because they require the SSE instruction set, which is not supported.
