Inside Intel's Core Architecture?What Makes It Better?

By midyear, the new Core architecture introduced at Intel's Developer Forum this week in San Francisco will provide a single framework that will extend across virtually all of the company's future processor offerings, from desktops to mobile computers to servers. The introduction of Core is one of the most important technology developments for Intel in years and may determine its success for the rest of the decade and beyond.

Core becomes Intel's single architecture for all of the company's mainstream processor offerings, with the exception of Itanium. It will let software developers more easily create applications that will easily port across both client and server implementations.

Intel promises Core will provide increased performance while maintaining or reducing power requirements for running its processors. It's a promise the company must keep if it expects to counter gains made by rival Advanced Micro Devices in the server market with its more efficient Opteron processors.

The advances in Core are tied to five specific innovations: wide dynamic execution, intelligent power capability, advanced smart cache, smart memory access, and advanced digital media boost.

While much of Core is based on the low-power Yonah processor architecture used in Intel's recent Core Duo processors for mobile computers, Stephen Pawlowski, chief technical officer for Intel's digital enterprise group and manager of architecture and planning, says Core is "a new design from the ground up, and not simply a re-do of Yonah."
