Message Text: Intel today took the wraps off its brand new, low-power microarchitecture named Silvermont, based on Intel's 22nm Tri-Gate SoC process and aimed squarely at low-power requirements in market segments from smartphones to the data center.

Silvermont will be the foundation for a range of products beginning to come to market later this year, and will also be manufactured using the company's 22nm Tri-Gate SoC manufacturing process.



"Silvermont is a leap forward and an entirely new technology foundation for the future that will address a broad range of products and market segments," said Dadi Perlmutter, Intel executive vice president and chief product officer. "Early sampling of our 22nm SoCs, including "Bay Trail" and "Avoton" is already garnering positive feedback from our customers. Going forward, we will accelerate future generations of this low-power microarchitecture on a yearly cadence."

Intel claims that the Silvermont microarchitecture delivers industry-leading performance-per-watt efficiency. The design brings increased support for a wider dynamic range and scales up and down in performance and power efficiency. On a variety of standard metrics, Silvermont also enables ~3x peak performance or the same performance at ~5x lower power over the current-generation Intel Atom processor core.

Intel's Silvermont microarchitecture was designed and co-optimized with Intel's 22nm SoC process using 3-D Tri-gate transistors.

Additional highlights of the Silvermont microarchitecture include a new out-of-order execution engine for high, single-threaded performance; a new multi-core and system fabric architecture scalable up to eight cores and enabling greater performance for higher bandwidth, lower latency and more efficient out-of-order support.

In addition, new IA instructions and technologies bring enhanced performance, virtualization and security management capabilities to support a wide range of products. These instructions build on Intel's existing support for 64-bit and the breadth of the IA software installed base.

Power management capabilities include a new intelligent burst technology, low- power C states and a wider dynamic range of operation taking advantage of Intel's 3-D transistors. Intel Burst Technology 2.0 support for single- and multi-core offers great responsiveness scaled for power efficiency.



"Through our design and process technology co-optimization we exceeded our goals for Silvermont," said Belli Kuttanna, Intel Fellow and chief architect. "By taking advantage of our strengths in microarchitecture development and leading-edge process technology, we delivered a technology package that enables significantly improved performance and power efficiency ? all while delivering higher frequencies. We're proud of this accomplishment and believe that Silvermont will offer a strong and flexible foundation for a range of new, low-power Intel SoCs."

Silvermont will serve as the foundation for a breadth of 22nm products expected in market later this year. Intel's quad-core "Bay Trail" SoC is scheduled for holiday 2013 tablets and will more than double the compute performance capability of Intel's current-generation tablet offering. Due to the flexibility of Silvermont, variants of the "Bay Trail" platform will also be used in market segments including entry laptop and desktop computers in innovative form factors.

Intel's "Merrifield" is scheduled to ship to Intel's customers by the end of this year. It will enable increased performance and battery life over current-generation products and brings support for context aware and personal services, ultra-fast connections for Web streaming, and increased data, device and privacy protection.

Intel's "Avoton" will enable leading energy efficiency and performance-per-watt for microservers, storage and scale out workloads in the data center. "Avoton" is Intel's second-generation Intel Atom processor SoC to provide full server product capability that customers require including 64-bit, integrated fabric, error code correction, Intel virtualization technologies and software compatibility. "Rangeley" is aimed at the network and communication infrastructure, specifically for entry-level to mid-range routers, switches and security appliances. Both products are scheduled for the second half of this year.

Concurrently, Intel is delivering advancements on its next-generation, 22nm Haswell microarchitecture for Intel Core processors to enable full-PC performance at lower power levels for innovative "2-in-1" form factors, and other mobile devices available later this year. Intel also plans to refresh its line of Intel Xeon processor families across the data center on 22nm technology, delivering better performance-per-watt and other features.
