Client Platform Considerations/Challenges

• Off power will be limiting in 2013 (0.5W – ErP Lot 6)– Enable supply of 80 PLUS* Bronze/Silver PSUs for desktop

– Spec improvement needed for 5VSTB efficiency at S5/S3 loads

• Discrete Graphics systems will have difficulty with idle power (ErP Lot 3)– Optimize power delivery, advocate component vendors for

good idle performance

• Auto Low Power State requirement in ErP Lot 3 (WIP)– Systems may have to support hibernate after 4 hours,

including desktops (not set-up today)

• High-end systems will have difficulty with idle/off power without targeted exemptions

1. Need to Converge on a consistent set of methodologies 2. Intel/Industry driving the global convergence framework

Summary/Call to Action• Global product energy regulations are trending toward

mandatory programs– Worldwide programs are adapting ENERGY STAR* as a basis for

energy efficiency regulations

– Use of voluntary ENERGY STAR criteria as market access requirement and a lack of single EE standard and metric will likely impact product cost and consumer choice

• Work with your industry association and standards bodies to harmonize to consistent methodologies with global applicability (Ecma/IEC/SPEC*/TGG/CSCI)

• Work with your suppliers to enable 80 PLUS* Bronze and Silver PSU for ErP Lot 3 regulation, and improve 5VSB PSU efficiency for S5/S3 loads for ErP Lot 6

• Develop Test Plans at an ENERGY STAR Test Facility to comply with changes in the enhanced qualification and verification programs by EOY2010

• Support Intel/Industry to drive global convergence on IT Energy Efficiency requirements & Specs

Risk Factors

26

The above statements and any others in this document that refer to plans and expectations for the second quarter, the year and the future are forward-looking statements that involve a number of risks and uncertainties. Many factors could affect Intel’s actualresults, and variances from Intel’s current expectations regarding such factors could cause actual results to differ materially from those expressed in these forward-looking statements. Intel presently considers the following to be the important factors that could cause actual results to differ materially from the corporation’s expectations. Demand could be different from Intel's expectations due to factors including changes in business and economic conditions; customer acceptance of Intel’s and competitors’ products; changes in customer order patterns including order cancellations; and changes in the level of inventory at customers. Intel operates in intensely competitive industries that are characterized by a high percentage of costs that are fixed or difficult to reduce in the short term and product demand that is highly variable and difficult to forecast. Additionally, Intel is in the process of transitioning to its next generation of products on 32nm process technology, and there could be execution issues associated with these changes, including product defects and errata along with lower than anticipated manufacturing yields. Revenue and the gross margin percentage are affected by the timing of new Intel product introductions and the demand for and market acceptance of Intel's products; actions taken by Intel's competitors, including product offerings and introductions, marketing programs and pricingpressures and Intel’s response to such actions; defects or disruptions in the supply of materials or resources; and Intel’s ability to respond quickly to technological developments and to incorporate new features into its products. The gross margin percentage could vary significantly from expectations based on changes in revenue levels; product mix and pricing; start-up costs, including costs associated with the new 32nm process technology; variations in inventory valuation, including variations related to the timing of qualifying products for sale; excess or obsolete inventory; manufacturing yields; changes in unit costs; impairments of long-lived assets, including manufacturing, assembly/test and intangible assets; the timing and execution of the manufacturing ramp and associated costs; and capacity utilization. Expenses, particularly certain marketing and compensation expenses, as well as restructuring and asset impairment charges, vary depending on the level of demand for Intel's products and the level of revenue and profits. The majority of our non-marketable equity investment portfolio balance is concentrated in the flash memory market segment, and declines in this market segment or changes in management’s plans with respect to our investment in this market segment couldresult in significant impairment charges, impacting restructuring charges as well as gains/losses on equity investments and interest and other. Intel's results could be impacted by adverse economic, social, political and physical/infrastructure conditions in countries where Intel, its customers or its suppliers operate, including military conflict and other security risks, natural disasters, infrastructure disruptions, health concerns and fluctuations in currency exchange rates. Intel’s results could be affected by the timing of closing of acquisitions and divestitures. Intel's results could be affected by adverse effects associated with product defects and errata (deviations from published specifications), and by litigation or regulatory matters involving intellectual property, stockholder, consumer, antitrust and other issues, such as the litigation and regulatory matters described in Intel's SEC reports. An unfavorable ruling could include monetary damages or an injunction prohibiting us from manufacturing or selling one or more products, precluding particular business practices, impacting our ability to design our products, or requiring other remedies such as compulsory licensing of intellectual property. A detailed discussion of these and other factors that could affect Intel’s results is included in Intel’s SEC filings, including the report on Form 10-Q for the quarter ended March 27, 2010.
