The AMD Athlon 64 X2 3600+ EE was a desktop processor with 2 cores, launched in August 2006. It is part of the Athlon 64 X2 lineup, using the Windsor architecture with Socket AM2. Athlon 64 X2 3600+ EE has 256 KB of L2 cache and operates at 2000 MHz. AMD is building the Athlon 64 X2 3600+ EE on a 90 nm production process using 154 million transistors. The multiplier is locked on Athlon 64 X2 3600+ EE, which limits its overclocking capabilities. With a TDP of 65 W, the Athlon 64 X2 3600+ EE consumes typical power levels for a modern PC. For communication with other components in the system, Athlon 64 X2 3600+ EE uses a PCI-Express Gen 2 connection. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability. 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 X2 3600+ EE, which greatly improves virtual machine performance.
