VIA Unveils Next-Generation Isaiah x86 Processor Architecture

VIA Technologies, Inc, a leading innovator of x86 silicon and platform technologies, today announced details of the VIA Isaiah Architecture, a new x86 processor architecture that will deliver significant boosts to the functionality and performance of desktop, mobile and ultra mobile PCs while minimizing power requirements, saving on battery life and enabling ultra compact system designs.

Designed from the ground up by the company's US-based processor design subsidiary, Centaur Technology Inc., the VIA Isaiah Architecture combines all the latest advances in x86 processor technology, including a 64-bit superscalar speculative out-of-order microarchitecture, high-performance multimedia computation, and a new virtual machine architecture. The first generation of Isaiah-based products will be pin-compatible with the VIA C7 processor family, enabling a smooth transition for system builders and providing them with an easy upgrade path for current designs.

The first processors implementing the VIA Isaiah Architecture will use proven 65 nanometer technology for greater power efficiency, which, combined with new enhanced power and thermal management capabilities, will ensure the best performance per watt on the market and help drive the rapidly emerging categories of green, silent and small form factor desktop PCs and home media centers, and ultra thin and light notebooks and mini-notes.

"Today is an exciting day for everyone at Centaur," commented Glenn Henry, President, Centaur Technology Inc. "With a team of less than one hundred first-class engineers, we have created from scratch the world's most power-efficient x86 processor architecture with state of the art features, outstanding performance, and flexible scalability for the future."

"The introduction of the new VIA Isaiah Architecture is an extremely significant milestone in VIA's processor business," commented Wenchi Chen, President and CEO, VIA Technologies, Inc. "In achieving these new levels of functionality and performance, it provides the ideal complement to our industry-leading family of low power VIA C7 processors and will enable us to further extend our growing presence in the global x86 processor market."

Optimized for a World of "Small is Beautiful" Devices
With its unique blend of high performance and low power consumption, the VIA Isaiah Architecture has been specifically optimized to meet the rapidly growing demand for smaller, more functional, and more stylish mobile and desktop computing and personal electronics devices that will allow people to fully enjoy the rich media content and interactivity of the broadband Internet lifestyle.

These devices range from easily portable slim and light notebooks and pocket-sized Ultra Mobile PCs and Ultra Mobile Devices with rich multimedia and wireless broadband capabilities to Small Form Factor Green PCs and Digital Entertainment Centers that combine space saving designs with minimal energy consumption.

VIA Isaiah Architecture Highlights
The VIA Isaiah Architecture has been specifically designed to deliver all the performance and features necessary for running the most demanding computing, entertainment, and connectivity applications on today's and tomorrow's Internet, including high-definition video, 3D games, imaging, and virtual worlds, within a very low power and thermal envelope that makes it ideal for small form factor mobile devices such as Mini-Notebooks and Ultra Mobile Devices. Its key highlights include the following:
  • 64-bit Superscalar Speculative Out-Of-Order MicroArchitecture

  • The VIA Isaiah Architecture comprises a host of advanced architectural features, including a superscalar and out of order architecture, macro-fusion and micro-fusion functionality, and sophisticated branch prediction, that significantly improve processor efficiency and performance. In addition, it also features a full and unrestricted 64-bit instruction set with plenty of headroom to support 64-bit operating systems and applications as they become available, and a new virtual machine architecture for running systems more securely and efficiently in virtual environments.

  • High-Performance Computation and Media Processing

  • As well as support for clock speeds of up to 2GHz in initial products and a high-speed, low power Front Side Bus scalable from 800MHz up to 1333MHz, the VIA Isaiah Architecture also has a highly-efficient cache subsystem with two 64KB L1 caches and 1MB exclusive L2 cache with 16-way associativity for more effective memory optimization.

    For further enhanced multimedia performance, the VIA Isaiah Architecture also integrates the world’s fastest x86 processor Floating Point Unit (FPU) with the ability to execute four floating point adds and four multiplies per clock and also featuring a new algorithm that minimizes latency. Support for new SSE instructions and a 128-bit wide integer data path further boost multimedia performance.

  • Advanced Power and Thermal Management

  • To minimize energy consumption and reduce heat, the VIA Isaiah Architecture utilizes new low power circuit techniques and in addition to aggressive management of active power includes support for the new "C6" power state, in which power is turned off to the caches.

    Extensive Adaptive PowerSaver Technology features further reduce power consumption and improve thermal management, including the unique TwinTurbo dual-PLL implementation, which acts like automatic transmission in permitting smooth transitions between activity states within one clock cycle, ensuring always-on service and minimize latency, as well as new mechanisms for managing the die temperature.

  • Scalable Upgrade to VIA C7 Processor

  • The VIA Isaiah Architecture is pin-to-pin compatible with the current VIA C7 processor family, enabling OEMs and motherboard makers to transition to the new architecture smoothly, and to fulfill a wider range of market segments with a single board or system design.

  • VIA PadLock Hardware Security Features-

  • To enhance the confidentiality, integrity, and authenticity of electronic data, the VIA Isaiah Architecture incorporates industry-leading on-die hardware cryptographic acceleration features within the VIA PadLock Security Engine, including the world's best random number generator (RNG), an AES Encryption Engine, SHA-1 and SHA-256 hashing for secure message digests for data integrity, and a new specialized “secure execution mode” that includes features such as a secure on-chip memory area and encrypted instruction fetching.

Is it going to be embedded BGA or is there a CPU socket in the making? There is a market for VIA embedded solutions/ CPUs here in Asia let's hope this eats into the $50~$100 CPU market.

So is this just a single core cpu or multi core?

If it was a multi-core CPU, that would've been the first thing VIA would've bragged about.

Well this is good news. I always like to be diversity in any market. I just hope they make a good and successful chip. I was never impressed by their chipsets.

its basically a conroe-L celeron isnt it

some of the specs they mention do seem very similar to intel - 800-1333 MHz FSB, 1MB cache, 65nm...

Also it says 2x64KB L1 cache, so it appears to be dual core.

Most VIA chips did have a close resemblance to AMD K7 in the past which had 64 K L1 code and 64K L1 data caches

Probably not. Data and instruction (trace) caches are often separate.

If it was 2 x L2 cache... that would indicate dual core.

At last something from VIA with 64bits, it was about time.

well with AMD going down hill, its about time another hero turned up to take up the fight & take it to Intels doorstep. good going VIA (even though you are more to do with industry & chipsets/IGPs then CPU's) VIA should really seize this opportunity to gain back some of their market share & also profits after Intel ripped VIA's license to make Chipsets for them (intel supported motherboards)

intel have the performance crown again - i'd love to see via take over the low power segment.

You gotta admit, a laptop with these things would be sweet, and i dont meen macbook air style (normal sized laptop with 8+ hours of battery...)
