The Intel Atom 330 was a mobile processor with 2 cores, launched in June 2008. It is part of the Atom lineup, using the Diamondville architecture with BGA 437. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 4 threads. Atom 330 has 512 KB of L2 cache per core and operates at 1600 MHz. Intel is making the Atom 330 on a 45 nm production node using 47 million transistors. The multiplier is locked on Atom 330, which limits its overclocking potential.
With a TDP of 8 W, the Atom 330 consumes extremely little energy.
The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability.
