Low Power by Design

Developed from the ground up for low power operation, the VIA C7 processor is based on the advanced VIA CoolStream Architecture and manufactured using IBM's state-of-the-art 90nm Silicon-on-Insulator (SOI) process, and delivers the greatest performance per watt in the business.

In addition to the world's best random number generator (RNG) and AES Encryption Engine in the previous processor generation, the VIA PadLock Security Engine in the VIA C7 processor adds SHA-1 and SHA-256 hashing for secure message digests, and a hardware based Montgomery Multiplier supporting key sizes up to 32K in length to accelerate public key cryptography, such as RSA. The VIA C7 also provides NX Execute Protection, providing protection from malicious software such as worms and viruses, and is used in Microsoft? Windows? XP with SP2. Integrating security directly onto the processor die ensures speeds and efficiency many times that available in software, yet with negligible impact on processor performance.

The VIA C7 processor heralds an era of practical pervasive security thanks to the , the world's fastest x86 security engine in the world featuring the most comprehensive suite of tools for key cryptographic operations.

Manufactured using IBM's leading 90nm Silicon-on-Insulator (SOI) process technology, the VIA C7 processor sets new standards in integration and performance, and all within an industry-leading thermal profile, making it ideal for a wide range of .

The principal design philosophy behind the VIA C7 processor incorporates the following key objectives:

VIA C7? Processor The new VIA C7? processor is the smallest, lowest power, most efficient and most secure native x86 processor in the world. Built on the advanced VIA CoolStream architecture, the 'Esther'core of the VIA C7 processor is designed to extend the digital lifestyle by combining robust performance of up to 2.0GHz with ultra low power consumption and highly efficient heat dissipation.
