VIA officially announced today the legendary dual-core Nano processor VIA Nano X2, known as the "mainstream PC" market, can be used for desktop computers, one machine and notebook. However, from the previous preview test, the main competitors of this low-power processor are still Intel Atom, AMD Fusion APU and so on. The Nano series is based on Centaur, an American processor design company acquired by VIA, and is focused on energy efficiency and low power consumption. At the end of May 2008, VIA released the Nano 2000 series of processors (internal code CNA), based on the new "Isaiah" microarchitecture, for the first time using 64-bit superscalar execution of the design. In early November 2009, VIA introduced an upgraded version of the Nano 3000 series (internal codenamed CNB), adding compatibility support for the SSE4 multimedia instruction set and virtualization technology. The new dual-core version released today, the internal code-named CNC, is based on the Nano 3000 series in architecture and technology, but it integrates two Isaiah cores in a single chip and upgrades the production process from Fujitsu's 65nm to TSMC's 40nm.
The VIA Nano X2's built-in dual core can undoubtedly greatly increase processor multithreading performance. While retaining the Nano architecture's low power consumption features, it also supports the SSE4 multimedia instruction set, native 64-bit computing, VT virtualization technology, VIA PadLock Hardware encryption technology, etc., and pin compatibility with the old VIA Nano, VIA C7-M, and VIA Eden processors, supporting chip sets such as the VX900 and VN1000. However, information on the specific models and specifications of the VIA Nano X2 processor has not yet been released.
The VIA Nano X2 processor is currently sampling to OEMs and motherboard manufacturers, and models equipped with this processor are expected to be available for sale during the quarter.
