IDF: Intel to change chip performance measures

Overall performance rather than clock speed

Intel plans in future to measure processor performance on the basis of processor performance by watt.

Intel CEO Paul Otellini is expected to explain the company's new benchmarks when he launches this year's Intel Developer Forum on 23 August in San Francisco, at the Moscone Center.

The move reflects the shift to powerful portable devices. Intel has been promoting clock speed as a performance measure for years, but will in future stress overall performance and power-efficiency.

Intel is also expected to create more chips that contain multiple processing cores, and deliver performance gains.

"It's not even so much performance per watt as it is fitting higher-performance computing into more constrained environments, either constrained by power, heat, noise or size," Dean McCarron, principal analyst at Mercury Research, told eWeek.

The move is very similar to Apple CEO Steve Jobs' presentation at this year's Worldwide Developer Conference, when he explained the move to Intel processors.

Intel has already promised to reveal a major change in the architecture used to build its chips at the event.
