| The VIA Isaiah Architecture.... |
VIA Technologies Inc. started shipping its current family of x86 processors in early 2000. Seven major versions—culminating in the VIA C7 processor—have shipped through the end of 2007. While compatible with the x86 instruction-set architecture, the internal architecture of these processors is very different from other x86 processor designs. This unique internal architecture yields processors that are significantly smaller (lower cost) and use significantly less power than other x86 processors from AMD™ and Intel®.
While the current VIA C7 processors are a perfect fit for many users and applications, a new architecture was needed to keep pace with the rapid introduction of new functions and improved performance from Intel. Accordingly, over the last four years, VIA made a major investment in its U.S.-based processor design subsidiary—Centaur Technology Inc.—to develop a completely new x86 processor architecture. The result is a new architecture, codenamed the VIA Isaiah Architecture, that complements current VIA products by offering significantly more function and performance within the same low-power envelope.
The initial products implementing the new VIA Isaiah Architecture will start shipping in the spring of 2008. These processors are built in 65nm technology and provide two to four times the performance of current VIA processors (at the same GHz) without a commensurate increase in cost and with little—if any—increase in power consumption.
This article summarizes the new VIA Isaiah Architecture with emphasis on the major underlying concepts and some of the unique features. |
