The Intel Atom Z560 was a mobile processor with 1 core, launched in June 2010. It is part of the Atom lineup, using the Silverthorne architecture with BGA 441. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 2 threads. Atom Z560 has 512 KB of L2 cache per core and operates at 2.133 GHz. Intel is building the Atom Z560 on a 45 nm production process using 47 million transistors. The multiplier is locked on Atom Z560, which limits its overclocking capabilities.
With a TDP of 2 W, the Atom Z560 consumes extremely little energy.
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 Atom Z560, which greatly improves virtual machine performance.
