The AMD Athlon 64 FX-76 was a desktop processor with 2 cores, that was never released. It is part of the Athlon 64 FX lineup, using the Windsor architecture with Socket F. To further increase overall system performance, up to two Athlon 64 FX-76 CPUs can work together in a multi-processor (SMP) configuration. Athlon 64 FX-76 has 1 MB of L2 cache and operates at 3.2 GHz. AMD is making the Athlon 64 FX-76 on a 90 nm production node using 227 million transistors. You may freely adjust the unlocked multiplier on Athlon 64 FX-76, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 125 W, the Athlon 64 FX-76 consumes a lot of power, so good cooling is definitely needed. AMD's processor supports DDR2 memory with a dual-channel interface. The highest officially supported memory speed is 667 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-76 uses a PCI-Express N/A connection. This processor does not have integrated graphics, you will need a separate graphics card.
The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability. Hardware virtualization is available on the Athlon 64 FX-76, which greatly improves virtual machine performance.
