The Intel Atom Z530P was a mobile processor with 1 core, launched in March 2009. It is part of the Atom lineup, using the Silverthorne architecture with BGA 437. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 2 threads. Atom Z530P has 512 KB of L2 cache per core and operates at 1600 MHz. Intel is making the Atom Z530P on a 45 nm production node using 47 million transistors. The multiplier is locked on Atom Z530P, which limits its overclocking potential.
With a TDP of 2 W, the Atom Z530P 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 Z530P, which greatly improves virtual machine performance.
