Atom 330 is an ultra-low power 32-bit x86 dual-core microprocessor introduced by Intel in late 2008. The 330 is specifically designed for nettops and various other mobile internet connected devices. This processors, which was fabricated on Intel's 45 nm process, was based on the Bonnell microarchitecture. The Atom 330 operates at 1.6 GHz with a TDP of 8 W with an average power consumption of 1.2 W. The MPU features a legacy 533 MT/s front-side bus capable of communicating with the Poulsbo chipset in both low-power CMOS mode as well as normal GTL mode (which also works with other chipsets).

The Atom 330 is actually two identical Atom 230 dies packaged together to form a dual-core Atom processor; it thus has exactly twice as many transistors, occupy twice the die size, and consume twice as much power.
