VIA Nano

VIA mengumumkan procesor paling baru untuk mobile procesor. Core NANO untuk arsitek Isaiah menjanjikan lebih cepat 4X dari model procesor C7 sebelumnya dengan pemakaian power yang sama.

Ada 2 versi yaitu L untuk mainstream desktop, mobile PC, U series yang lebih hemat power.
Kedua seri tersebut dibuat dengan pin yang sama atau kompatibel.

Via mengatakan, NANO menjadi procesor pertama dengan teknologi 64 bit dan superscalar. Walaupun kecil tetapi dapat menjalankan kontain Blu-ray disc. Model paling kecil memiliki kecepatan 1Ghz diseri U dan tertinggi dengan 1.8Ghz untuk seri L
Kemampuan super hemat misalnya pada model U2300, hanya membutuhkan power 5W saja ketika bekerja penuh. Dan idle akan turun sampai 100mW.

VIA saat ini sudah mengirim tipe NANO ke OEM dan produsen mainboard. Perkiraan akan mulai dipasarkan pada kuartal 3 mendatang.

According to the specifications, initial production versions of the 1.0GHz VIA Nano ULV processor will have a maximum Thermal Design Power (TDP) of 5 watts with an idle power of just 100mW. At the other end of the spectrum is the 1.8 GHz VIA Nano processor a 25 watts TDP and 500mW idle power rating.


This high-level block diagram gives a basic architectural overview of the VIA Nano processor. Other features of the design include:

* 64-bit Superscalar Speculative Out-Of-Order MicroArchitecture: 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: The high-speed, low power VIA V4 Front Side Bus starting at 800MHz, plus a high speed floating point unit, support for new SSE instructions, and two 64KB L1 caches and 1MB exclusive L2 cache with 16-way associativity gives a big boost to multimedia performance.

* 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.

* 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.

* Enhanced VIA PadLock Security Engine: Industry-leading on-die hardware cryptographic acceleration and security features, including dual quantum random number generators, an AES Encryption Engine, NX execute protection, and SHA-1 and SHA-256 hashing.


VIA is also quick to make a comparison of the security features offered in the latest x86 processors. As the above chart shows, the Nano has a number of cryptographic acceleration and security features integrated into the CPU die, which Intel and AMD do not.





Please note, the benchmark results posted above comparing the VIA Nano and C7 processor were provided by VIA to show the comparative performance of the two processors when coupled with the new VIA VX800 digital media IGP chipset. A variety of applications were tested, grouped into three main categories - productivity, multimedia, and synthetics.

As the numbers show, the Nano offers about 1.6x to 3.2x the performance of the C7 clock-for-clock while within a similar, albeit somewhat higher, power envelope.


VIA also provided a Performance Per Watt comparison between a 1.6GHz Intel Celeron-M 520 and a 1.6GHz VIA Nano. The test was based on the overall score from an OfficeBench 2007 benchmark run and the TDP for a 1.6GHz Celeron-M (31 watts) versus the TDP of a 1.6GHz VIA Nano (17 watts). As per VIA's results, the Nano offers 1.9x the perf per watt of a similarly clocked Celeron M. We hope to verify these results four ourselves, sometime in the near future.

According to VIA, Nano processors are available now for OEMs and motherboard vendors, and systems featuring VIA Nano processors should hit the market in Q3 2008.
