The AMD Athlon 64 FX-57 was a desktop processor with 1 core, launched in June 2005, at an MSRP of $1031. It is part of the Athlon 64 FX lineup, using the San Diego architecture with Socket 939. Athlon 64 FX-57 has 1 MB of L2 cache and operates at 2.8 GHz. AMD is making the Athlon 64 FX-57 on a 90 nm production node using 114 million transistors. You may freely adjust the unlocked multiplier on Athlon 64 FX-57, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency. With a TDP of 104 W, the Athlon 64 FX-57 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. For communication with other components in the computer, Athlon 64 FX-57 uses a PCI-Express N/A connection. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability. Inside the box you will not only find the processor, but also a Yes cooler. The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability.
