VIA Nano™ Processor

VIA Nano™ Processor The first 64-bit, superscalar 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. Building on the market-leading energy efficiency of the VIA C7® processor family, the VIA Nano processor family offers as much as four times the performance within the same power range to extend VIA's performance per watt leadership, while pin compatibility with VIA C7 processors will ensure a smooth transition for OEMs and motherboard vendors, providing them with an easy upgrade path for current system or board designs. The VIA Nano processor family leverages advanced 65 nanometer process technology for the ideal blend of powerful performance and energy efficiency. Underscoring VIA's leadership in processor miniaturization, the VIA Nano processor comes with ultra compact dimensions, enabling a new generation of small form factor designs and new, smaller applications for the x86 platform.

Key Architectural Features 64-bit Next Generation Architecture The superscalar, speculative out-of-order 'Isaiah, architecture of the VIA Nano processor family supports a full 64-bit instruction set and provides for macro-fusion and micro-fusion functionality, and sophisticated branch prediction for greater processor efficiency and performance. High-Performance Computation and Media Processing VIA Nano processors utilize the high-speed, low power VIA V4 Front Side Bus up to 800MHz, while support for new SSE instructions and two 64KB L1 caches and 1MB exclusive L2 cache with 16-way associativity give a big boost to multimedia performance. In particular, the VIA Nano processor places significant emphasis on high-performance floating-point execution, using a completely new algorithm for floating-point adds that results in the lowest floating-point add latency of any x86 processor. Similarly, the floating-point multiplier has the lowest latency of any x86 processor. In practical terms, this means the VIA Nano processor provides exceptionally smooth play back of Blu-ray Disc™ and other HD video formats, which can have encrypted media streams of up to 40Mbps, and low latency rendering of 3D images for an excellent PC gaming experience. The following chart shows the VIA Nano processor's computational benefits over the popular VIA C7 processor: Advanced Power and Thermal Management Aggressive management of active power includes support for the new "C6" power state, Adaptive PowerSaver™ Technology, new circuit techniques and mechanisms for managing the die temperature, reducing power draw and improving thermal management. Through the above innovations in processor architecture, the VIA Nano processor is able to offer the significant performance improvements that come with the new superscalar architecture, within the same low power envelope of the VIA C7 processor. Initial production versions of the 1.0 GHz VIA Nano ULV processor will have a maximum Thermal Design Power (TDP) of just 5 watts (and an idle power of just 100mW), scaling up to 25 watts for the 1.8 GHz VIA Nano processor (500mW idle power). An increase in computational performance, coupled with maintenance of the power envelope has naturally resulted in a greatly improved performance per watt. The VIA Nano processor is easily the leading processor in terms of performance per watt on the market. Performance statistic based on overall score on OfficeBench 2007 TDP for 1.6GHz Celeron-M = 31 watts; TDP for 1.6GHz VIA Nano = 17 watts OS = Windows Vista Enterprise To find out more about the advanced thermal management of the VIA Nano processor, you can view an architectural overview here. Scalable Upgrade to VIA C7® Processor Pin-to-pin compatibility with current VIA C7 processors enables a smooth transition for OEMs and mainboard vendors, enabling them to offer a wider range of products for different markets with a single board or system design. Greener Technology In addition to full compliance with RoHS and WEEE regulations, product manufacturing will be halogen-free and lead-free at launch, helping to promote a cleaner environment and more sustainable computing.
