Today VIA Technologies announced the new VIA Nano processor family based on the VIA Isaiah Architecture. The VIA Nano is aimed to compete with the Intel Atom CPUs.

The VIA Nano processor family offers as much as four times the performance within the same power range of the VIA C7. The VIA Nano is pin compatibility with VIA C7 processors, which will ensure a smooth transition for OEMs and motherboard vendors, and provides them with an easy upgrade path for current system or board designs.
The first 64-bit, superscalar, speculative out-of-order processors in VIA's x86 platform portfolio, VIA Nano processors have been specifically designed to revitalize traditional desktop and notebook PC markets, delivering truly optimized performance for the most demanding computing, entertainment and connectivity applications, including Blu-ray Disc HD video playback and the latest PC games, such as Crysis.

The VIA Nano processor family leverages Fujitsu's advanced 65 nanometer process technology for enhanced power efficiency, and augments that with aggressive power and thermal management features within the compact 21mm x 21mm nanoBGA2 package for an idle power as low as 100mW (0.1W), extending the reach of power efficient green and silent PCs, thin and light notebooks and mini-notes around the world.

The first available VIA Nano CPUs include VIA Nano L2100 processor 1.8GHz, VIA Nano L2200 processor 1.6Ghz, VIA Nano U2400 processor 1.3Ghz, VIA Nano U2500 processor 1.2Ghz, and VIA Nano U2300 processor 1.0Ghz.

VIA Nano processors are available now for OEMs and motherboard vendors, while systems featuring VIA Nano processors are expected to market in Q3 2008.
