Intel Atom Processor Family

The Intel Atom processor family's modest power requirements provide very long battery life, making it a perfect choice for the growing netbook market. Although its small cache size and modest clock speed ranges make it less powerful than most notebook processors, the Atom family includes models with more advanced features such as hyperthreading, dual processor cores, 64-bit support, and VT-x hardware virtualization. Atom processors are available in five series: Z500, D500, N400, D400, and N200, 300, and 200.

Atom D500 Series

The dual-core D500 series is currently the most advanced member of the Atom family. It has the following features:

  • Two processor cores
  • 1MB cache
  • Integrated graphics
  • Hyperthreading technology
  • Supports 64-bit operating systems and applications
  • DMI connection between CPU and chipset
  • DDR2 memory support
  • 13 watts max TDP
  • Based on "Pineview" architecture

Atom D400 Series

The D400 series is a reduced performance version of the D500 series. It has the following features:

  • Two processor cores
  • 512KB cache
  • Integrated graphics
  • Hyperthreading technology
  • Supports 64-bit operating systems and applications
  • DMI connection between CPU and chipset
  • DDR2 memory support
  • 10 watts max TDP
  • Based on "Pineview" architecture

Atom N400 Series

The N400 series is a single-core version of the D400 series. It has the following features:

  • One processor core
  • 512KB cache
  • Integrated graphics
  • Hyperthreading technology
  • Supports 64-bit operating systems and applications
  • DMI connection between CPU and chipset
  • DDR2 memory support
  • 5.5 watts max TDP
  • Based on "Pineview" architecture

Atom Z500 Series

The Z500 series includes a wide range of clock speeds and feature sets. It has the following features:

  • One processor core
  • 512KB cache
  • Hyperthreading technology (all except Z510)
  • Intel VT-x hardware virtualization (Z520 and higher models)
  • Supports 64-bit operating systems and applications
  • 533MHz or 400MHz front side bus (varies by model)
