The Intel Atom Z530 was a mobile processor with 1 core, launched in April 2008. 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 Z530 has 512 KB of L2 cache per core and operates at 1600 MHz. Intel is building the Atom Z530 on a 45 nm production process using 47 million transistors. The multiplier is locked on Atom Z530, which limits its overclocking capabilities.
With a TDP of 2 W, the Atom Z530 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 Z530, which greatly improves virtual machine performance.
